What to Know About the C.D.C. Guidelines on Vaccinated Travel

In updated recommendations, the federal health agency said both domestic and international travel was low risk for fully vaccinated Americans. But travel remains far from simple.

The Centers for Disease Control and Prevention updated its guidance for fully vaccinated Americans in April, saying that traveling both domestically and internationally was low risk.

The long-awaited recommendations were issued by federal health officials after a series of studies found that vaccines administered in the United States were robustly effective in preventing infections in real-life conditions.

One is considered fully vaccinated two weeks after receiving the single dose of the Johnson & Johnson vaccine, or two weeks after receiving the second dose of the Pfizer-BioNTech or Moderna shots.

If you decide to travel, you might still have some questions. Here are the answers.

Will I still need to wear a mask and socially distance while traveling?

Yes. Under federal law, masks must be worn at airports in the United States, onboard domestic flights and in all transport hubs. The C.D.C. says that as long as coronavirus measures are taken in these scenarios, including mask wearing, fully vaccinated Americans can travel domestically without having to take a test or quarantine, although the agency warns that some states and territories may keep their local travel restrictions and recommendations in place.

For those wishing to travel internationally, a coronavirus test will not be required before departure from the United States unless mandated by the government of their destination. Vaccinated travelers are still required to get tested three days before travel by air into the United States, and are advised to take a test three to five days after their return, but will not need to self-quarantine.

Can I go abroad?

Yes, but only to countries that will have you.

More than half the world’s countries have reopened to tourists from the United States, including the countries of the European Union , which on June 18 added the United States to its “safe list” of countries, meaning that American travelers can now visit. While the European Union 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 based on their own epidemiological criteria, which means they may require testing or vaccination.

Some places like Turkey, Croatia and Montenegro had already been welcoming Americans with negative test results. Greece joined that growing list in May, ahead of most European countries, opening to fully vaccinated tourists and other foreigners with a negative test.

Many Caribbean nations have reopened to American tourists, but each has its own coronavirus protocols and entry requirements.

Here’s a full list of countries Americans can currently travel to.

What about domestic travel? Is it free and clear to cross state borders?

If you are fully vaccinated, the C.D.C. says you can travel freely within the United States and that you do not need to get tested, or self-quarantine, before or after traveling. But some states and local governments may choose to keep travel restrictions in place, including testing, quarantine and stay-at-home orders. Hawaii , for instance, still has travel restrictions in place.

Before you travel across state lines, check the current rules at your destination.

How are they going to check that I’m fully vaccinated?

Right now, the best way to prove that you have been vaccinated is to show your vaccine card .

Digital vaccine and health certificates showing that people have been vaccinated or tested are in various stages of development around the world and are expected, eventually, to be widely used to speed up travel.

The subject of “ vaccine passports ” is currently one of the most hotly debated topics within the travel industry, with questions over the equity of their use and concerns over health and data privacy.

In early April, Gov. Ron DeSantis of Florida issued an executive order that would ban local governments and state businesses from requiring proof of vaccination for services.

And in March, the European Union endorsed its own vaccine certificate , which some countries are already using, with more expected to adopt it by July 1.

But what about my kids? What’s the guidance on traveling with unvaccinated people?

The C.D.C. advises people against travel unless they have been vaccinated. If you must travel, the agency recommends testing one to three days before a trip and following all coronavirus guidance at your destination.

In May, the F.D.A. expanded its emergency use authorization of the Pfizer-BioNTech coronavirus vaccine to include adolescents between 12 and 15 years of age.

All air passengers aged two and older coming into the United States, including fully vaccinated people, are required to have a negative Covid-19 test result taken no more than three days before they board their flight.

What is my moral obligation to the places I visit where most people are not vaccinated?

The United States inoculation rollout has been among the fastest in the world, but there is a stark gap between its rapid rollout and the vaccination programs in different countries. Some nations have yet to report a single dose being administered.

Many countries are currently seeing a surge in new cases and are implementing strict coronavirus protocols, including mask mandates in public spaces, capacity limits at restaurants and tourist sites and other lockdown restrictions.

It is important to check coronavirus case rates, measures and medical infrastructure before traveling to your destination and not to let your guard down when you get there. Even though you are fully vaccinated, you may still be able to transmit the disease to local communities who have not yet been inoculated.

CDC drops all countries from its highest-risk covid category

The agency overhauled its advisory system and will now reserve Level 4 for special circumstances

The Centers for Disease Control and Prevention updated its international covid-19 travel advisory system Monday, designating its highest-risk category for extreme scenarios.

As of Monday, the CDC dropped all countries from its “Level 4” category, now labeled “Special Circumstances/Do Not Travel.” About 120 destinations now have a Level 3 advisory — including Australia, the United Kingdom, Italy and many other popular European destinations — for “high” levels of the coronavirus, while 12 destinations sit at Level 2. Another 55 are designated Level 1, its lowest-risk level.

“To help the public understand when the highest level of concern is most urgent, this new system will reserve Level 4 travel health notices for special circumstances, such as rapidly escalating case trajectory or extremely high case counts, emergence of a new variant of concern, or healthcare infrastructure collapse,” the agency said in a statement last week.

The three lower-level warnings will continue to be determined mainly by 28-day coronavirus incidence or case counts. “With this new configuration, travelers will have a more actionable alert for when they should not travel to a certain destination (Level 4), regardless of vaccination status, until we have a clearer understanding of the COVID-19 situation at that destination,” the statement continued.

The CDC's do not travel list, explained

During the pandemic, the CDC has updated weekly its list of countries travelers should avoid because of the coronavirus, with its “Level 4” warning indicating very high levels of the coronavirus and instructing all travelers to avoid the area.

Before this last update , about 90 countries were in the Level 4 category.

The State Department also shares its own advisories . Those include threats such as terrorism and natural disasters, while factoring in CDC recommendations.

We asked: Should I avoid travel to a Level 4 country?

Last month, in a letter to new White House coronavirus response coordinator Ashish Jha, the U.S. Travel Association called for an end to “avoid travel” advisories, among other pandemic travel practices.

“The CDC should ensure that Americans are not dissuaded from traveling to any place with COVID-19 case rates that are equal to, or less than, the case rates prevailing in the U.S.,” the letter read. “As conditions continue to improve, the CDC should end all ‘avoid travel’ advisories for vaccinated individuals.”

However, the advisory system still has a useful function.

“The U.S. State Department and CDC’s travel advisories are accurate and up to date,” Abinash Virk, the former head of the travel clinic at the Mayo Clinic in Minnesota and an infectious-disease specialist, previously told The Washington Post by email. “They are reliable resources and extremely helpful to determine if travel to a certain location will be safe from a COVID-19 perspective or not.”

Last month, the CDC dropped cruises from its list of travel warnings. It had included notices for cruise ships since March 2020, when cruise lines stopped sailing from U.S. waters for more than a year.
