The Centers for Disease Control and Prevention updated its guidance for fully vaccinated Americans on Friday, 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.
Still, the C.D.C. is not recommending travel at this time because of the rising number of cases of the coronavirus, both at home and abroad.
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.
Most of Europe is still off-limits to American citizens, although some countries such as Iceland are allowing in vaccinated visitors from the United States and elsewhere. Other places like Turkey, Croatia and Montenegro and have been welcoming Americans with negative test results, while Greece plans to open up to fully vaccinated tourists and other foreigners with a negative test in May.
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 travel to.
What about domestic travel? Is it free and clear to cross state borders?
Domestic travel has been complicated this past year, with the states and territories instituting their own travel restrictions and recommendations throughout the pandemic (and frequently updating them).
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.
Before you travel across state lines, check the current rules at your destination and whether the state is waiving testing and quarantines for vaccinated people. You can find a list of current restrictions here.
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.
On Friday, Gov. Ron DeSantis of Florida issued an executive order that would ban local governments and state businesses from requiring proof of vaccination for services.
Last month, the European Union endorsed its own vaccine certificate, but individual European countries are still expected to set their own rules for travel requirements this summer.
