Vaccines for Travelers

Vaccines protect travelers from serious diseases. Depending on where you travel, you may come into contact with diseases that are rare in the United States, like yellow fever. Some vaccines may also be required for you to travel to certain places.

Getting vaccinated will help keep you safe and healthy while you’re traveling. It will also help make sure that you don’t bring any serious diseases home to your family, friends, and community.

On this page, you'll find answers to common questions about vaccines for travelers.

Which vaccines do I need before traveling?

The vaccines you need to get before traveling will depend on few things, including:

• Where you plan to travel . Some countries require proof of vaccination for certain diseases, like yellow fever or polio. And traveling in developing countries and rural areas may bring you into contact with more diseases, which means you might need more vaccines before you visit.
• Your health . If you’re pregnant or have an ongoing illness or weakened immune system, you may need additional vaccines.
• The vaccinations you’ve already had . It’s important to be up to date on your routine vaccinations. While diseases like measles are rare in the United States, they are more common in other countries. Learn more about routine vaccines for specific age groups .

How far in advance should I get vaccinated before traveling?

It’s important to get vaccinated at least 4 to 6 weeks before you travel. This will give the vaccines time to start working, so you’re protected while you’re traveling. It will also usually make sure there’s enough time for you to get vaccines that require more than 1 dose.

Where can I go to get travel vaccines?

Start by finding a:

• Travel clinic
• Health department
• Yellow fever vaccination clinic

What resources can I use to prepare for my trip?

Here are some resources that may come in handy as you’re planning your trip:

• Visit CDC’s travel website to find out which vaccines you may need based on where you plan to travel, what you’ll be doing, and any health conditions you have.
• Download CDC's TravWell app to get recommended vaccines, a checklist to help prepare for travel, and a personalized packing list. You can also use it to store travel documents and keep a record of your medicines and vaccinations.
• Read the current travel notices to learn about any new disease outbreaks in or vaccine recommendations for the areas where you plan to travel.
• Visit the State Department’s website to learn about vaccinations, insurance, and medical emergencies while traveling.

Traveling with a child? Make sure they get the measles vaccine.

Measles is still common in some countries. Getting your child vaccinated will protect them from getting measles — and from bringing it back to the United States where it can spread to others. Learn more about the measles vaccine.

Which Vaccinations Are Required for Travel?

By Cassie Shortsleeve

A trip abroad requires you to be up-to-date on a whole checklist of things these days: travel insurance, airline policies, visas, passports , and, as far as your health is concerned, vaccines. Yet while the COVID-19 pandemic has made us acutely aware of the importance of staying healthy on the road, travel vaccines have always been a mainstay of safe travel—a crucial tool in avoiding the (often expensive) headaches of getting sick , and treating sicknesses, abroad.

Whether you have travel on the horizon or want to be prepared for 2023 trips and beyond, this guide will get you up to speed on the vaccinations required for travel depending on your destination, itinerary, and health status. Follow the below steps to protect your immune system in another country.

Make sure you’re current with routine vaccines

The Centers for Disease Control and Prevention (CDC) recommends all travelers be up to date on routine vaccines before travel. Routine vaccines include shots like COVID-19; chickenpox; Hepatitis A and B; Influenza; Measles, Mumps, Rubella (MMR); Polio; and more. The CDC has a full list of routine vaccines here .

“‘Routinely recommended vaccines’ are vaccines that have been considered very important to prevent common diseases in the population to start,” says Lin H. Chen , M.D. director of the Travel Medicine Center at Mount Auburn Hospital in Cambridge, Massachusetts, and the former president of the International Society of Travel Medicine (ISTM).

Routine vaccines protect against disease that exists at low levels (chickenpox) or barely exists at all (measles) in the U.S. They also protect against severe disease from diseases that are still present in the United States (influenza or COVID-19). Generally, they’re given in childhood or adolescence—though some are given through adulthood—so it’s always a good idea to double-check your vaccination records.

When traveling, routine shots are especially important because international travel increases your chances of both contracting and spreading diseases that aren’t common in the U.S. A good example of this is measles. While it’s practically non-existent in the U.S., international travel increases your risk of exposure and popular destinations including Europe still have measles outbreaks.

It’s worth double checking your status even if you think you’re up to date: “During the pandemic, some routine vaccination programs may have suffered lapses, so there is concern that diseases may become more common,” says Dr. Chen.

The routine vaccination recommendations have also changed over the years (the addition of the COVID-19 vaccine to the list is an example) and it’s easy to let vaccines like tetanus ( generally needed every 10 years ) lapse.

“It is even recommended at this time that certain adults who are traveling who have not had a polio vaccine for many years and are traveling to a risk area get an additional dose of the polio vaccine,” says Elizabeth D. Barnett , M.D., a professor at Boston University Medical School and a leader in the field of travel and tropical Medicine.

If you’re traveling with a child , talk to your pediatrician: Rules around vaccination can be different for babies traveling internationally. A baby who is not leaving the U.S., for example, gets their first dose of the MMR vaccine at 12 months; if they will be leaving the country, they get the first dose at six months .

Utilize official resources to learn more about vaccination recommendations around the world

“Understanding the epidemiology of where diseases are circulating is really important,” says Dr. Chen.

That’s why, generally, she sends travelers to the CDC’s website , which outlines exactly what additional vaccines you may need for essentially every country in the world. All you have to do is plug in your destination and you’ll find information about vaccines and medications, health travel notices, COVID-19 travel information, and more.

Start a conversation with your primary care doctor—then consider seeing a travel medicine specialist

It’s always good to start a conversation with your primary care doctor about vaccines before you travel, but if your itinerary is complex, involving multiple countries, being in rural areas, areas without good hygiene, or areas where you may not be able to protect yourself from mosquito- or food-borne illnesses, or if you have questions based on what you found on the CDC website or your own personal health history, consider asking your physician for a referral to a travel medicine specialist or travel clinic.

After all, when it comes to vaccinations required for travel, it’s not just about where you travel, but how you travel.

“The art of travel medicine is listening to where the person is going, what they're going to be doing, and making a decision based on the risk-benefit ratio,” says Dr. Barnett. A travel medicine doctor will be able to analyze disease trends and trip details such as how long you’ll be traveling or how well you’ll be able to protect yourself against mosquitoes. “You have to really dig into those things,” she says.

Take a vaccine called the Japanese encephalitis vaccine, which prevents a type of encephalitis (inflammation of the brain). “We can't just say the risk is present in a specific country, because the risk depends on the time of year, whether the disease is being transmitted at that time, the exact location—rural areas, especially farming regions are associated with much higher risk — whether there's a local outbreak situation going on, and more.”

You may not be able to get every shot you need at your primary care doctor’s office either. The yellow fever vaccine, for example (which you may need if you’re traveling somewhere like Sub-Saharan Africa or specific parts of South America), is only available at special travel clinics or public health settings, says Dr. Barnett. You can find a list of travel medicine clinics on the CDC’s website.

Your health background (what diseases you’ve had in the past, whether or not you’re immune-suppressed, and if you’re more predisposed to a certain condition) also play a role in what vaccines to consider. (A very small subset of people vaccinated against yellow fever, for example, experience severe adverse events, says Dr. Barnett.)

The bottom line

For many people and many trips, discussing travel plans with your primary care doctor and using the CDC’s destination feature for vaccine guidance will suffice. Other, more complex trips require a visit to a travel clinic. If you’re aiming to get into one, start the process at least a month before your departure date—appointments can be hard to get and your body needs time to build up immunity from any additional vaccines you may require.

Frequently Asked Questions: Guidance for Travelers to Enter the U.S.

Updated Date: April 21, 2022

Since January 22, 2022, DHS has required non-U.S. individuals seeking to enter the United States via land ports of entry and ferry terminals at the U.S.-Mexico and U.S.-Canada borders to be fully vaccinated for COVID-19 and provide proof of vaccination upon request.  On April 21, 2022, DHS announced that it would extend these requirements. In determining whether and when to rescind this order, DHS anticipates that it will take account of whether the vaccination requirement for non-U.S. air travelers remains in place.

These requirements apply to non-U.S. individuals who are traveling for essential or non-essential reasons. They do not apply to U.S. citizens, Lawful Permanent Residents, or U.S. nationals.

Effective November 8, 2021, new air travel requirements applied to many noncitizens who are visiting the United States temporarily. These travelers are also required to show proof of COVID-19 vaccination. All air travelers, including U.S. persons, must test negative for COVID-19 prior to departure. Limited exceptions apply. See  CDC guidance  for more details regarding air travel requirements.

Below is more information about what to know before you go, and answers to Frequently Asked Questions about cross-border travel.

Entering the U.S. Through a Land Port of Entry or Ferry Terminal

Q. what are the requirements for travelers entering the united states through land poes.

A:  Before embarking on a trip to the United States, non-U.S. travelers should be prepared for the following:

• Possess proof of an approved COVID-19 vaccination as outlined on the  CDC  website.
• During border inspection, verbally attest to their COVID-19 vaccination status. 
• Bring a  Western Hemisphere Travel Initiative  compliant border crossing document, such as a valid passport (and visa if required), Trusted Traveler Program card, a Department of State-issued Border Crossing Card, Enhanced Driver’s License or Enhanced Tribal Card when entering the country. Travelers (including U.S. citizens) should be prepared to present the WHTI-compliant document and any other documents requested by the CBP officer.

 Q. What are the requirements to enter the United States for children under the age of 18 who can't be vaccinated?

A:  Children under 18 years of age are excepted from the vaccination requirement at land and ferry POEs.

Q: Which vaccines/combination of vaccines will be accepted?

A:  Per CDC guidelines, all Food and Drug Administration (FDA) approved and authorized vaccines, as well as all vaccines that have an Emergency Use Listing (EUL) from the World Health Organization (WHO), will be accepted.

Accepted Vaccines:

• More details are available in CDC guidance  here .
• 2 weeks (14 days) after your dose of an accepted single-dose COVID-19 vaccine;
• 2 weeks (14 days) after your second dose of an accepted 2-dose series;
• 2 weeks (14 days) after you received the full series of an accepted COVID-19 vaccine (not placebo) in a clinical trial;
• 2 weeks (14 days) after you received 2 doses of any “mix-and-match” combination of accepted COVID-19 vaccines administered at least 17 days apart.

Q. Is the United States requiring travelers to have a booster dose to be considered fully vaccinated for border entry purposes?

A:  No. The CDC guidance for “full vaccination” can be found here.

Q: Do U.S. citizens or lawful permanent residents need proof of vaccination to return to the United States via land POEs and ferry terminals?

A:  No. Vaccination requirements do not apply to U.S. citizens, U.S. nationals, or Lawful Permanent Residents (LPRs). Travelers that exhibit signs or symptoms of illness will be referred to CDC for additional medical evaluation.

Q: Is pre- or at-arrival COVID testing required to enter the United States via land POEs or ferry terminals?

A: No, there is no COVID testing requirement to enter the United States via land POE or ferry terminals. In this respect, the requirement for entering by a land POE or ferry terminal differs from arrival via air, where there is a requirement to have a negative test result before departure.

Processing Changes Announced on January 22, 2022 

Q: new changes were recently announced. what changed on january 22.

A:  Since January 22, 2022, non-citizens who are not U.S. nationals or Lawful Permanent Residents have been required to be vaccinated against COVID-19 to enter the United States at land ports of entry and ferry terminals, whether for essential or nonessential purposes. Previously, DHS required that non-U.S. persons be vaccinated against COVID-19 to enter the United States for nonessential purposes.  Effective January 22, all non-U.S. individuals, to include essential travelers, must be prepared to attest to vaccination status and present proof of vaccination to a CBP officer upon request. DHS announced an extension of this policy on April 21, 2022.

Q: Who is affected by the changes announced on January 22?

A: This requirement does not apply to U.S. citizens, U.S. nationals, or U.S. Lawful Permanent Residents. It applies to other noncitizens, such as a citizen of Mexico, Canada, or any other country seeking to enter the United States through a land port of entry or ferry terminal.

Q: Do U.S. citizens need proof of vaccination to return to the United States via land port of entry or ferry terminals?

A: Vaccination requirements do not apply to U.S. Citizens, U.S. nationals or U.S. Lawful Permanent Residents. Travelers that exhibit signs or symptoms of illness will be referred to CDC for additional medical evaluation. 

Q: What is essential travel?

A:  Under the prior policy, there was an exception from temporary travel restrictions for “essential travel.” Essential travel included travel to attend educational institutions, travel to work in the United States, travel for emergency response and public health purposes, and travel for lawful cross-border trade (e.g., commercial truckers). Under current policy, there is no exception for essential travel.

Q: Will there be any exemptions? 

A: While most non-U.S. individuals seeking to enter the United States will need to be vaccinated, there is a narrow list of exemptions consistent with the Centers for Disease Control and Prevention (CDC) Order in the air travel context.

• Certain categories of individuals on diplomatic or official foreign government travel as specified in the CDC Order
• Children under 18 years of age;
• Certain participants in certain COVID-19 vaccine trials as specified in the CDC Order;   
• Individuals with medical contraindications to receiving a COVID-19 vaccine as specified in the CDC Order;
• Individuals issued a humanitarian or emergency exception by the Secretary of Homeland Security;
• Individuals with valid nonimmigrant visas (excluding B-1 [business] or B-2 [tourism] visas) who are citizens of a country with limited COVID-19 vaccine availability, as specified in the CDC Order
• Members of the U.S. Armed Forces or their spouses or children (under 18 years of age) as specified in the CDC Order; and
• Individuals whose entry would be in the U.S. national interest, as determined by the Secretary of Homeland Security.

Q: What documentation will be required to show vaccination status?

A:  Non-U.S. individuals are required to be prepared to attest to vaccination status and present proof of vaccination to a CBP officer upon request regardless of the purpose of travel.

The current documentation requirement remains the same and is available on the CDC website . Documentation requirements for entry at land ports of entry and ferry terminals mirror those for entry by air.

Q: What happens if someone doesn’t have proof of vaccine status?

A: If non-U.S. individuals cannot present proof of vaccination upon request, they will not be admitted into the United States and will either be subject to removal or be allowed to withdraw their application for entry.

Q: Will incoming travelers be required to present COVID-19 test results?

A: There is no COVID-19 testing requirement for travelers at land border ports of entry, including ferry terminals.

Q: What does this mean for those who can't be vaccinated, either due to age or other health considerations? 

A: See CDC guidance for additional information on this topic. Note that the vaccine requirement does not apply to children under 18 years of age.

Q: Does this requirement apply to amateur and professional athletes?

A: Yes, unless they qualify for one of the narrow CDC exemptions.

Q: Are commercial truckers required to be vaccinated?

A: Yes, unless they qualify for one of the narrow CDC exemptions. These requirements also apply to bus drivers as well as rail and ferry operators.

Q. Do you expect border wait times to increase?

A:  As travelers navigate these new travel requirements, wait times may increase. Travelers should account for the possibility of longer than normal wait times and lines at U.S. land border crossings when planning their trip and are kindly encouraged to exercise patience.

To help reduce wait times and long lines, travelers can take advantage of innovative technology, such as facial biometrics and the CBP OneTM mobile application, which serves as a single portal for individuals to access CBP mobile applications and services.

Q: How is Customs and Border Protection staffing the ports of entry? 

A: CBP’s current staffing levels at ports of entry throughout the United States are commensurate with pre-pandemic levels. CBP has continued to hire and train new employees throughout the pandemic. CBP expects some travelers to be non-compliant with the proof of vaccination requirements, which may at times lead to an increase in border wait times. Although trade and travel facilitation remain a priority, we cannot compromise national security, which is our primary mission. CBP Office of Field Operations will continue to dedicate its finite resources to the processing of arriving traffic with emphasis on trade facilitation to ensure economic recovery.

Q: What happens if a vaccinated individual is traveling with an unvaccinated individual?  

A:  The unvaccinated individual (if 18 or over) would not be eligible for admission.

Q: If I am traveling for an essential reason but am not vaccinated can I still enter?

A:  No, if you are a non-U.S. individual. The policy announced on January 22, 2022 applies to both essential and non-essential travel by non-U.S. individual travelers. Since January 22, DHS has required that all inbound non-U.S. individuals crossing U.S. land or ferry POEs – whether for essential or non-essential reasons – be fully vaccinated for COVID-19 and provide related proof of vaccination upon request.

Q: Are sea crew members on vessels required to have a COVID vaccine to disembark?

A:  Sea crew members traveling pursuant to a C-1 or D nonimmigrant visa are not excepted from COVID-19 vaccine requirements at the land border. This is a difference from the international air transportation context.

Entering the U.S. via Air Travel

Q: what are the covid vaccination requirements for air passengers to the united states  .

A:  According to CDC requirements [www.cdc.gov/coronavirus/2019-ncov/travelers/noncitizens-US-air-travel.html | Link no longer valid], most noncitizens who are visiting the United States temporarily must be fully vaccinated prior to boarding a flight to the United States. These travelers are required to show proof of vaccination. A list of covered individuals is available on the CDC website.  

Q: What are the COVID testing requirements for air passengers to the United States?  

A:  Effective Sunday, June 12 at 12:01 a.m. ET, CDC will no longer require pre-departure COVID-19 testing for U.S.-bound air travelers.

What to Know About Testing and Vaccine Requirements for Travel

Do you need to be vaccinated or have a negative Covid-19 test for your next trip? Check this guide before traveling domestically or abroad.

By Concepción de León

As vaccinations ramp up and regulations loosen for people in the United States, many are planning travel for summer and beyond, with experts predicting that July 4 will be the biggest travel weekend since the beginning of the pandemic.

But with regulations shifting, people might have questions about testing or vaccination requirements for their trips. The Centers for Disease Control and Prevention recently eased travel recommendations to more than 100 countries. On June 18, the European Union added the United States to its “safe list” of countries , meaning that both vaccinated and unvaccinated American travelers should now be able to visit the 27 member countries, but these member states are allowed to set their own requirements and restrictions for travelers.

In the United States, the C.D.C. has advised that vaccinated people no longer need to wear masks in most places and released new travel guidelines that said domestic travel is safe for them. But travelers must take note of local advice and regulations, as these can vary state by state.

Here’s everything you need to consider about testing and vaccinations before you travel within the U.S. or internationally.

Are there testing and vaccination requirements for domestic travel?

For most places, no. You do not need to be vaccinated for any domestic travel. Hawaii is the only state that requires a negative test for travel.

In Hawaii, the test must be administered within 72 hours of arrival and the results uploaded to its Safe Travel platform to avoid a mandatory quarantine when entering the state.

Alternatively in Hawaii, you can also provide proof that you’ve recovered from Covid-19 in the past 90 days, including both a positive test result and a letter from a doctor clearing you to travel.

The state’s governor, David Ige, said this month that people who received their vaccination in the state of Hawaii may bypass testing and quarantine requirements starting on June 15, and that anyone vaccinated in the U.S. will be able to enter Hawaii without testing once the state has reached a 60 percent vaccination rate.

If you are unvaccinated, you should continue to adhere to social distancing and mask-wearing protocols while traveling domestically, the C.D.C. said . You can use the C.D.C.’s Travel Planner to check guidelines by state.

What are the testing and vaccination rules for international travel?

While testing and vaccination requirements vary by destination country, everyone arriving in the U.S. — even vaccinated Americans — must present a negative test result upon entry .

Many nations are still closed to American travelers. Those that are open may require a negative test, proof of vaccination or evidence of recovery (or a combination of these) to enter.

The United Kingdom , for instance, requires that American travelers, regardless of vaccination status, provide proof of a negative test taken within 72 hours of departure, quarantine upon arrival and take two additional tests during their stay. Children under 11 are exempt from these requirements, as are some other people depending on their reason for travel.

Some European countries have been allowing in Americans who are vaccinated or who can show a negative test. Americans are on the European Union’s “safe list” of countries, but while the bloc aims to take a coordinated approach to travel this summer, member states will be allowed to set their own requirements for travelers from individual countries, which could include testing and vaccination.

The E.U. “safe list” also applies to Europe’s border-free Schengen Zone, which includes non-E.U. countries such as Norway, Switzerland, Iceland and Lichtenstein.

Canada is still closed to Americans , with few exceptions, and will remain so until at least early July, said Patty Hajdu, the country’s minister of health, in a news conference in June.

The U.S.-Mexico land border is closed for nonessential travel until at least June 21, but air travel is allowed and the country does not require a negative test for entry. Because of its high risk level, the C.D.C. recommends that travelers be fully vaccinated before traveling to Mexico.

Consult the C.D.C.’s inventory of international travel health notices for more information on regulations by country.

“Travelers should always check with their airline and the embassy of the country they are visiting to ensure they have the proper documentation required to enter the country,” said Perry Flint, a spokesman for The International Air Transport Association, a global airline industry group.

What test should I take, and where and when?

To enter the U.S., travelers must show a negative result to a nucleic acid amplification test (NAAT) — PCR is a type of NAAT test — or an antigen test, also known as a rapid test, taken in the three days before departure, according to the C.D.C .

Some airports offer on-site testing, such as Heathrow Airport in England, or Rome’s Fiumicino International Airport in Italy.

Josh Alexander, a New York-based luxury travel agent for Protravel International, said that many international hotels, including most Four Seasons hotels and resorts , are offering on-site rapid tests for free or at a nominal cost.

Testing at local clinics is also available in many places, though you should check availability at your destination ahead of time and book if you can. It may also come at a high cost. Mr. Alexander said that PCR tests abroad can range from $50 to $150.

The C.D.C. said that it allows for a three-day time frame rather than 72 hours to allow flexibility in the time of day the test can be taken. For instance, if you are flying out on a Friday, the test may be taken at any time on Tuesday.

But, when it comes to international destinations, Mr. Alexander recommends erring on the side of caution when timing your test by calculating it based on time of arrival at your destination.

“Rules are constantly changing,” he said, “so we’re just trying to always tell people they should always be as conservative as possible to eliminate any gray area.”

What are the requirements for minors?

The C.D.C. testing recommendations apply to all children 2 years and older, which means your toddler also needs to deliver a negative Covid-19 test to enter the U.S. from abroad. When traveling, children should wear masks, practice social distancing and wash hands often, the C.D.C. said .

“If the kids are age 12 and older, get ’em vaccinated,” said William Schaffner, an infectious disease expert at Vanderbilt University, in an email.

If you’re traveling to a country within the European Union that is open to travelers from the U.S., children who cannot be vaccinated should have a negative PCR test taken no more than 72 hours before arrival at your destination, and additional testing may be required upon arrival.

Travelers should check with their airline or destination country website for relevant requirements.

What if I want to go on a cruise?

Rules vary from one cruise line to another, with some planning to require that all passengers and crew be vaccinated, and others adopting a hybrid model.

But recent laws passed in Florida and Texas banning businesses from requiring proof of vaccination to use their services may complicate this plan.

Celebrity Cruises, set to be the first U.S. cruise ship to restart operations on June 26 from Fort Lauderdale, Fla., said it’s optimistic that a resolution would be reached in time . It is requiring that guests 16 years and older be vaccinated, while children will be tested at the terminal.

Carnival Cruises said on Monday that its first ship would set sail from the Port of Galveston, in Texas, on July 3 and would be available only for vaccinated passengers. Norwegian, which will begin to operate cruises from Miami in August, said it will require the same through October 31 and has threatened to skip Florida ports if the state does not allow cruise lines an exemption from the law banning vaccine requirements.

Christine Duffy, the president of Carnival Cruise Line, said in a statement on June 7 that “the current CDC requirements for cruising with a guest base that is unvaccinated will make it very difficult to deliver the experience our guests expect, especially given the large number of families with younger children who sail with us.”

“As a result, our alternative is to operate our ships from the U.S. during the month of July with vaccinated guests,” she said.

But even if you are vaccinated, you must also consider the requirements of the country where the cruise is disembarking. The Caribbean island of St. Maarten, for instance, where Celebrity Cruises started sailing on June 5, requires a negative test in addition to proof of vaccination.

What documents should I bring with me if I travel?

This will also depend on where you’re going, but a good rule of thumb is to carry your physical vaccine card, if you have it, and proof of a negative test, if it is required.

Mr. Alexander, the travel agent, recommends people bring the original documents. While a number of digital health certificates — which show vaccine status and test results — are in the works, he said, they are not yet widely accepted. You should check, also, that your document is in the correct language. The United Kingdom , for instance, requires that test results be in English, Spanish or French.

CommonPass , from the Geneva-based nonprofit the Commons Project Foundation, and the I.A.T.A. Travel Pass are two apps providing digital access to vaccine and testing records for travel. The European Union will be releasing its own digital Covid certificate for E.U. citizens by July 1, though it is unclear whether Americans will be able to use it.

You should check with your airline to see if the app you want to use will be accepted at your destination. Both the CommonPass and I.A.T.A. websites list destinations and airline partners accepting the digital health certificates.

Mr. Alexander added that some countries, such as Croatia, may also require proof of a return flight or confirmation of your hotel booking or other accommodation, though this is rare. In South Africa, which has implemented a curfew, travelers may need to show their flight ticket to law enforcement officers to show they are allowed to be in transit.

But these shifting regulations should not dissuade people from traveling, Mr. Alexander said.

“If you’re vaccinated and you’re following safe precautions, you can still have a great experience,” he said.

INTRODUCTION

Immunization needs are based on the traveler's prior immunizations, health conditions, and likely exposures while traveling ( table 1 ). Those exposures depend upon the countries and regions to be visited and on the nature of potential exposures to infectious agents. For example, travelers with short-term tourism itineraries may have different requirements from those with longer-term occupational exposures. A pretravel consultation enables updating of routine immunizations to protect against illness due to infections for which there is an increased risk of exposure during travel (such as diphtheria, measles, mumps, and varicella) [ 3 ].

Issues related to immunizations for travelers are reviewed here. Other travel-related medical issues and measures to prevent malaria are discussed separately. (See "Travel advice" and "Prevention of malaria infection in travelers" .)

WEBSITES FOR ADDITIONAL GUIDANCE

● United States Centers for Disease Control and Prevention (CDC) – Information on the indications, dosing, side effects, timing, and contraindications for immunizations in travelers are provided by the CDC in a biennial, Health Information for International Travel [ 4 ], with ongoing updates in an online version.

● World Health Organization (WHO) – The WHO also has online information that includes vaccines or dosing regimens approved outside the United States [ 5 ]. Information may be found on the CDC website and the WHO website . Guidance may also be found via GlobalTravEpiNet (GTEN), which has web-based tools for providers and patients based on CDC recommendations.

From vaccines to testing: What travelers need to know before the new US travel system on Nov. 8

• The U.S. is launching a new travel system on Nov. 8.
• Vaccinated foreign air travelers will need to show proof of full vaccination and test for COVID-19.
• The new travel system also adds more stringent testing requirements for unvaccinated U.S. travelers.

The United States is about to make it much easier for vaccinated international travelers to visit.  

The White House announced that a new air travel system will take effect Nov. 8, allowing entry for fully vaccinated foreign tourists .  The system is set to launch nearly two years after the U.S. began imposing travel restrictions to prevent the spread of COVID-19 . 

The move by the White House will essentially have the U.S. drop its travel ban on dozens of countries while also making entry more challenging for the unvaccinated. The new system will allow entry for foreign nationals only with vaccinations approved for emergency use by the World Health Organization and would add testing requirements for unvaccinated Americans.

Here’s what we know about the new travel requirements:

What are the entry requirements for foreign nationals?

Starting Nov. 8, non-citizen, non-immigrant air travelers   will need to show proof of full vaccination as well as a pre-departure negative coronavirus test taken within three days of travel before they can board a plane to the U.S.

Acceptable forms of proof of vaccination include:

• Digital or paper verifiable record, such as a vaccination certificate or a digital pass with a QR code.  
• Nonverifiable paper record, such as a printout of a COVID-19 vaccination record or COVID-19 vaccination certificate.
• Nonverifiable digital record, such as a digital photo of a vaccination card or record, downloaded vaccine record, downloaded vaccination certificate or a mobile phone application without a QR code.  

The U.S. will accept nucleic acid amplification tests, including PCR tests, and antigen tests. The rules will go into effect for passengers on planes leaving for the U.S. at or after 12:01 a.m. ET on Nov. 8.  

Airlines will collect basic personal contact information   from all U.S.-bound travelers for contact tracing. Airlines are required to keep the information on hand so the Centers for Disease Control and Prevention   can reach out to travelers who may have been infected or exposed to COVID-19.

Masking will be required, but there will be no quarantine mandate for vaccinated travelers or unvaccinated children .

► US  travel bans: How COVID-19 travel restrictions have impacted families and couples

The change will make entering the U.S. possible for travelers from countries now listed on the U.S. travel ban, which prohibits entry for travelers who have been in any of the regions within the past 14 days. The travel ban  took effect in early 2020 and includes :

• United Kingdom
• Republic of Ireland
• South Africa
• The European Schengen area (Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland, Monaco, San Marino and Vatican City)

Currently, the U.S. asks international air passengers only to get tested within three days of their flight to the U.S. and show either the negative test result or proof of recovery  from COVID-19 before boarding. 

What about the land borders with Mexico and Canada?

New travel rules will also take effect for foreign nationals arriving by land or passenger ferry.

Starting Nov. 8, fully vaccinated foreign nationals can cross the land borders for nonessential reasons such as tourism or visiting friends and family . These travelers will need to verbally attest to their reason for travel and vaccination status and be prepared to show proof of vaccination  upon request. U.S. Customs and Border Protection will accept both digital and paper records showing proof of vaccination, including documents not in English.   Foreign nationals will also need appropriate travel documentation to enter the country.  

CBP will spot-check travelers' vaccination documents, and those without documented proof of vaccination can be denied entry. Travelers under 18 will be exempt from the vaccination requirement as long as they are traveling with a fully vaccinated adult, according to Matthew Davies, CBP's executive director of admissibility and passenger programs.  

The new travel rules will go into effect as soon as a port of entry opens on Nov. 8, or at midnight for ports that operate 24 hours a day changes will go into effect at midnight on Nov. 8 for ports that operation 24 hours a day.  

U.S. citizens reentering the country should also bring a Western Hemisphere Travel Initiative document, such as a valid passport, trusted traveler program card, enhanced driver's license or enhanced tribal card. 

Entry rules along the border will change again in early January, with all travelers – including those traveling for essential purposes – required to show proof of full vaccination.

Which vaccines does the US accept for travel?

The CDC has announced that vaccines approved for emergency use by the U.S. Food and Drug Administration and World Health Organization will be accepted for air travel. White House officials expect the CDC to approve the same vaccines for travelers entering the U.S. by land or ferry.  

The FDA has authorized three COVID-19 vaccines for emergency use during the pandemic: Moderna, Johnson & Johnson and Pfizer-BioNTech, the last of which has received the FDA's full stamp of approval.

Vaccines with WHO approval for emergency use include:

• Johnson & Johnson
• Pfizer-BioNTech
• Oxford-AstraZeneca/Covishield 

The CDC confirmed that it would accept a mix-and-match approach to vaccinations. Travelers who have any combination of FDA- or WHO-approved vaccines will be considered fully vaccinated.

The new travel policy does not accept foreign travelers who have had COVID and received just one shot in a two-dose series. White House press secretary Jen Psaki said Tuesday that the administration will "continue to review" its entry requirements.  

► Covaxin gets WHO emergency approval: Travelers vaccinated with Covaxin can enter US   

► 'You feel lonely and left out': These fully vaccinated travelers want to visit the US. They may not be allowed in.

How do the new rules affect kids? 

Foreign nationals under 18 are exempt from the vaccination requirement. Children under two will not need to take a pre-departure COVID test.

Kids 2 and older traveling with a fully vaccinated adult can test three days prior to departure, while children traveling alone or with unvaccinated adults will need to get tested within one day of departure. 

Currently, all air passengers 2 or older, including U.S. citizens and permanent residents, need to show a negative coronavirus test to fly to the U.S.

What are the entry requirements for Americans?

The new travel system adds more stringent testing requirements for unvaccinated U.S. travelers.

Starting Nov. 8, unvaccinated U.S. citizens and permanent residents will need to take a test one day before departure and test again upon arrival in the U.S. 

► New travel rules: What US travelers need to know about the new COVID rules for international flights

Entry requirements will not change for vaccinated Americans. They will still need to show proof of a negative coronavirus test taken no more than three days before departure. 

Americans will not need to be fully vaccinated to board international flights to the U.S.

Are there any exemptions?

There is a limited set of travelers who are exempt from the vaccine requirement for entry.

Children under 18, certain COVID-19 vaccine clinical trial participants and travelers with adverse reactions to the vaccines – such as people who have had severe anaphylactic allergic reactions to a prior COVID-19 vaccine –  will be exempt.

People traveling on non-tourist visas from countries with less than 10% of its population vaccinated who need to enter the U.S. for emergency or humanitarian reasons are also exempt from the vaccine requirement. There are about 50 countries considered to have low vaccine availability at this time.

These exempt travelers will generally need to show that they will comply with public health mandates, including a requirement to be vaccinated in the U.S. if they plan to stay more than 60 days.  

Unless they have recovered from COVID-19 within the last 90 days, unvaccinated travelers  must agree to be tested with a COVID-19 viral test three to five days after their arrival and quarantine for seven days, even if their post-arrival test comes back negative. 

Unvaccinated travelers who are not U.S. citizens or permanent residents must also agree to self-isolate if their post-arrival test is positive or if they develop COVID-19 symptoms. 

Unvaccinated children under 18 will not need to quarantine but will still need to take a post-arrival test. 

► Who is exempt?: These select groups of unvaccinated foreign travelers can enter the US

The CDC will not give exemptions  to people who object to the vaccinations due to religious or moral convictions. 

There will also be testing accommodations for travelers who can prove they recently recovered from the coronavirus. These travelers will need to show a positive COVID-19 viral test result on a sample taken no more than 90 days before their flight's departure and a letter from a licensed healthcare provider or public health official saying they are cleared for travel.

Important notice to immigrant visa applicants concerning vaccination requirements.

United States immigration law requires immigrant visa applicants to obtain certain vaccinations (listed below) prior to the issuance of an immigrant visa. Panel physicians who conduct medical examinations of immigrant visa applicants are required to verify that immigrant visa applicants have met the vaccination requirements, or that it is medically inappropriate for the visa applicant to receive one or more of the listed vaccinations:

• Hepatitis A
• Hepatitis B
• Influenza type b (Hib)
• Meningococcal
• Pneumococcal
• Tetanus and diphtheria toxoids

In order to assist the panel physican, and to avoid delays in the processing of an immigrant visa, all immigrant visa applicants should have their vaccination records available for the panel physician's review at the time of the immigrant medical examination. Visa applicants should consult with their regular health care provider to obtain a copy of their immunization record, if one is available. If you do not have a vaccination record, the panel physician will work with you to determine which vaccinations you may need to meet the requirement. Certain waivers of the vaccination requirement are available upon the recommendation of the panel physician.

Only a physician can determine which of the listed vaccinations are medically appropriate for you, given your age, medical history and current medical condition. For more detailed information, please visit the Centers for Disease Control and Prevention, Panel Physician Technical Instructions for Vaccination .

Malaria information for Mexico.

Cases of measles are on the rise worldwide. Travelers are at risk of measles if they have not been fully vaccinated at least two weeks prior to departure, or have not had measles in the past, and travel internationally to areas where measles is spreading.

All international travelers should be fully vaccinated against measles with the measles-mumps-rubella (MMR) vaccine, including an early dose for infants 6–11 months, according to  CDC’s measles vaccination recommendations for international travel .

Measles (Rubeola) - CDC Yellow Book

Rabid dogs are commonly found in Mexico. However, if you are bitten or scratched by a dog or other mammal while in Mexico, rabies treatment is often available. 

Consider rabies vaccination before your trip if your activities mean you will be around dogs or wildlife.

Travelers more likely to encounter rabid animals include

• Campers, adventure travelers, or cave explorers (spelunkers)
• Veterinarians, animal handlers, field biologists, or laboratory workers handling animal specimens
• Visitors to rural areas

Since children are more likely to be bitten or scratched by a dog or other animals, consider rabies vaccination for children traveling to Mexico. 

Rabies - CDC Yellow Book

Recommended for most travelers, especially those staying with friends or relatives or visiting smaller cities or rural areas.

Typhoid - CDC Yellow Book

Dosing info - Typhoid

Learn actions you can take to stay healthy and safe on your trip. Vaccines cannot protect you from many diseases in Mexico, so your behaviors are important.

Eat and drink safely

Food and water standards around the world vary based on the destination. Standards may also differ within a country and risk may change depending on activity type (e.g., hiking versus business trip). You can learn more about safe food and drink choices when traveling by accessing the resources below.

• Choose Safe Food and Drinks When Traveling
• Water Treatment Options When Hiking, Camping or Traveling
• Global Water, Sanitation and Hygiene | Healthy Water
• Avoid Contaminated Water During Travel

You can also visit the Department of State Country Information Pages for additional information about food and water safety.

Prevent bug bites

Bugs (like mosquitoes, ticks, and fleas) can spread a number of diseases in Mexico. Many of these diseases cannot be prevented with a vaccine or medicine. You can reduce your risk by taking steps to prevent bug bites.

What can I do to prevent bug bites?

• Cover exposed skin by wearing long-sleeved shirts, long pants, and hats.
• Use an appropriate insect repellent (see below).
• Use permethrin-treated clothing and gear (such as boots, pants, socks, and tents). Do not use permethrin directly on skin.
• Stay and sleep in air-conditioned or screened rooms.
• Use a bed net if the area where you are sleeping is exposed to the outdoors.

What type of insect repellent should I use?

• FOR PROTECTION AGAINST TICKS AND MOSQUITOES: Use a repellent that contains 20% or more DEET for protection that lasts up to several hours.
• Picaridin (also known as KBR 3023, Bayrepel, and icaridin)
• Oil of lemon eucalyptus (OLE) or para-menthane-diol (PMD)
• 2-undecanone
• Always use insect repellent as directed.

What should I do if I am bitten by bugs?

• Avoid scratching bug bites, and apply hydrocortisone cream or calamine lotion to reduce the itching.
• Check your entire body for ticks after outdoor activity. Be sure to remove ticks properly.

What can I do to avoid bed bugs?

Although bed bugs do not carry disease, they are an annoyance. See our information page about avoiding bug bites for some easy tips to avoid them. For more information on bed bugs, see Bed Bugs .

For more detailed information on avoiding bug bites, see Avoid Bug Bites .

Some diseases in Mexico—such as dengue, Zika, leishmaniasis, and Chagas disease—are spread by bugs and cannot be prevented with a vaccine. Follow the insect avoidance measures described above to prevent these and other illnesses.

Stay safe outdoors

If your travel plans in Mexico include outdoor activities, take these steps to stay safe and healthy during your trip.

• Stay alert to changing weather conditions and adjust your plans if conditions become unsafe.
• Prepare for activities by wearing the right clothes and packing protective items, such as bug spray, sunscreen, and a basic first aid kit.
• Consider learning basic first aid and CPR before travel. Bring a travel health kit with items appropriate for your activities.
• If you are outside for many hours in heat, eat salty snacks and drink water to stay hydrated and replace salt lost through sweating.
• Protect yourself from UV radiation : use sunscreen with an SPF of at least 15, wear protective clothing, and seek shade during the hottest time of day (10 a.m.–4 p.m.).
• Be especially careful during summer months and at high elevation. Because sunlight reflects off snow, sand, and water, sun exposure may be increased during activities like skiing, swimming, and sailing.
• Very cold temperatures can be dangerous. Dress in layers and cover heads, hands, and feet properly if you are visiting a cold location.

Stay safe around water

• Swim only in designated swimming areas. Obey lifeguards and warning flags on beaches.
• Practice safe boating—follow all boating safety laws, do not drink alcohol if driving a boat, and always wear a life jacket.
• Do not dive into shallow water.
• Do not swim in freshwater in developing areas or where sanitation is poor.
• Avoid swallowing water when swimming. Untreated water can carry germs that make you sick.
• To prevent infections, wear shoes on beaches where there may be animal waste.

Leptospirosis, a bacterial infection that can be spread in fresh water, is found in Mexico. Avoid swimming in fresh, unchlorinated water, such as lakes, ponds, or rivers.

Keep away from animals

Most animals avoid people, but they may attack if they feel threatened, are protecting their young or territory, or if they are injured or ill. Animal bites and scratches can lead to serious diseases such as rabies.

Follow these tips to protect yourself:

• Do not touch or feed any animals you do not know.
• Do not allow animals to lick open wounds, and do not get animal saliva in your eyes or mouth.
• Avoid rodents and their urine and feces.
• Traveling pets should be supervised closely and not allowed to come in contact with local animals.
• If you wake in a room with a bat, seek medical care immediately. Bat bites may be hard to see.

All animals can pose a threat, but be extra careful around dogs, bats, monkeys, sea animals such as jellyfish, and snakes. If you are bitten or scratched by an animal, immediately:

• Wash the wound with soap and clean water.
• Go to a doctor right away.
• Tell your doctor about your injury when you get back to the United States.

Consider buying medical evacuation insurance. Rabies is a deadly disease that must be treated quickly, and treatment may not be available in some countries.

Reduce your exposure to germs

Follow these tips to avoid getting sick or spreading illness to others while traveling:

• Wash your hands often, especially before eating.
• If soap and water aren’t available, clean hands with hand sanitizer (containing at least 60% alcohol).
• Don’t touch your eyes, nose, or mouth. If you need to touch your face, make sure your hands are clean.
• Cover your mouth and nose with a tissue or your sleeve (not your hands) when coughing or sneezing.
• Try to avoid contact with people who are sick.
• If you are sick, stay home or in your hotel room, unless you need medical care.

Avoid sharing body fluids

Diseases can be spread through body fluids, such as saliva, blood, vomit, and semen.

Protect yourself:

• Use latex condoms correctly.
• Do not inject drugs.
• Limit alcohol consumption. People take more risks when intoxicated.
• Do not share needles or any devices that can break the skin. That includes needles for tattoos, piercings, and acupuncture.
• If you receive medical or dental care, make sure the equipment is disinfected or sanitized.

Know how to get medical care while traveling

Plan for how you will get health care during your trip, should the need arise:

• Carry a list of local doctors and hospitals at your destination.
• Review your health insurance plan to determine what medical services it would cover during your trip. Consider purchasing travel health and medical evacuation insurance.
• Carry a card that identifies, in the local language, your blood type, chronic conditions or serious allergies, and the generic names of any medications you take.
• Some prescription drugs may be illegal in other countries. Call Mexico’s embassy to verify that all of your prescription(s) are legal to bring with you.
• Bring all the medicines (including over-the-counter medicines) you think you might need during your trip, including extra in case of travel delays. Ask your doctor to help you get prescriptions filled early if you need to.

Many foreign hospitals and clinics are accredited by the Joint Commission International. A list of accredited facilities is available at their website ( www.jointcommissioninternational.org ).

In some countries, medicine (prescription and over-the-counter) may be substandard or counterfeit. Bring the medicines you will need from the United States to avoid having to buy them at your destination.

Malaria is a risk in some parts of Mexico. If you are going to a risk area, fill your malaria prescription before you leave, and take enough with you for the entire length of your trip. Follow your doctor’s instructions for taking the pills; some need to be started before you leave.

Select safe transportation

Motor vehicle crashes are the #1 killer of healthy US citizens in foreign countries.

In many places cars, buses, large trucks, rickshaws, bikes, people on foot, and even animals share the same lanes of traffic, increasing the risk for crashes.

Be smart when you are traveling on foot.

• Use sidewalks and marked crosswalks.
• Pay attention to the traffic around you, especially in crowded areas.
• Remember, people on foot do not always have the right of way in other countries.

Riding/Driving

Choose a safe vehicle.

• Choose official taxis or public transportation, such as trains and buses.
• Ride only in cars that have seatbelts.
• Avoid overcrowded, overloaded, top-heavy buses and minivans.
• Avoid riding on motorcycles or motorbikes, especially motorbike taxis. (Many crashes are caused by inexperienced motorbike drivers.)
• Choose newer vehicles—they may have more safety features, such as airbags, and be more reliable.
• Choose larger vehicles, which may provide more protection in crashes.

Think about the driver.

• Do not drive after drinking alcohol or ride with someone who has been drinking.
• Consider hiring a licensed, trained driver familiar with the area.
• Arrange payment before departing.

Follow basic safety tips.

• Wear a seatbelt at all times.
• Sit in the back seat of cars and taxis.
• When on motorbikes or bicycles, always wear a helmet. (Bring a helmet from home, if needed.)
• Avoid driving at night; street lighting in certain parts of Mexico may be poor.
• Do not use a cell phone or text while driving (illegal in many countries).
• Travel during daylight hours only, especially in rural areas.
• If you choose to drive a vehicle in Mexico, learn the local traffic laws and have the proper paperwork.
• Get any driving permits and insurance you may need. Get an International Driving Permit (IDP). Carry the IDP and a US-issued driver's license at all times.
• Check with your auto insurance policy's international coverage, and get more coverage if needed. Make sure you have liability insurance.
• Avoid using local, unscheduled aircraft.
• If possible, fly on larger planes (more than 30 seats); larger airplanes are more likely to have regular safety inspections.
• Try to schedule flights during daylight hours and in good weather.

Medical Evacuation Insurance

If you are seriously injured, emergency care may not be available or may not meet US standards. Trauma care centers are uncommon outside urban areas. Having medical evacuation insurance can be helpful for these reasons.

Maintain personal security

Use the same common sense traveling overseas that you would at home, and always stay alert and aware of your surroundings.

Before you leave

• Research your destination(s), including local laws, customs, and culture.
• Monitor travel advisories and alerts and read travel tips from the US Department of State.
• Enroll in the Smart Traveler Enrollment Program (STEP) .
• Leave a copy of your itinerary, contact information, credit cards, and passport with someone at home.
• Pack as light as possible, and leave at home any item you could not replace.

While at your destination(s)

• Carry contact information for the nearest US embassy or consulate .
• Carry a photocopy of your passport and entry stamp; leave the actual passport securely in your hotel.
• Follow all local laws and social customs.
• Do not wear expensive clothing or jewelry.
• Always keep hotel doors locked, and store valuables in secure areas.
• If possible, choose hotel rooms between the 2nd and 6th floors.

To call for emergency services while in Mexico, dial 066, 060, or 080. Write these numbers down to carry with you during your trip.

Learn as much as you can about Mexico before you travel there. A good place to start is the country-specific information on Mexico from the US Department of State.

Americans in Mexico have been arrested for purchasing souvenirs that were, or looked like, antiques and that local customs authorities believed were national treasures. Familiarize yourself with any local regulations for antiques and follow these tips:

• When you are considering purchasing an authentic antique or a reproduction, ask if you are allowed to export these items before you purchase them.
• If you buy a reproduction, document on the customs form that it is a reproduction.
• If you buy an authentic antique, obtain the necessary export permit (often from the national museum).

Healthy Travel Packing List

Use the Healthy Travel Packing List for Mexico for a list of health-related items to consider packing for your trip. Talk to your doctor about which items are most important for you.

Why does CDC recommend packing these health-related items?

It’s best to be prepared to prevent and treat common illnesses and injuries. Some supplies and medicines may be difficult to find at your destination, may have different names, or may have different ingredients than what you normally use.

If you are not feeling well after your trip, you may need to see a doctor. If you need help finding a travel medicine specialist, see Find a Clinic . Be sure to tell your doctor about your travel, including where you went and what you did on your trip. Also tell your doctor if you were bitten or scratched by an animal while traveling.

If your doctor prescribed antimalarial medicine for your trip, keep taking the rest of your pills after you return home. If you stop taking your medicine too soon, you could still get sick.

Malaria is always a serious disease and may be a deadly illness. If you become ill with a fever either while traveling in a malaria-risk area or after you return home (for up to 1 year), you should seek immediate medical attention and should tell the doctor about your travel history.
