Do You Need a Covid-19 Vaccine Booster to Travel?

Two Covid-19 shots aren’t enough for some travelers anymore. Destinations are now increasingly requiring boosters for easy entry.

Spain, the Netherlands and Singapore are among several places that have mandated or will soon mandate that US travelers who had their last vaccine dose 270 days or more ago show proof of a booster shot or face additional testing requirements.


How do Covid-19 requirements influence your travel planning? Join the conversation below.

As of Monday, 88 million Americans had received a booster, or 41.5% of the country’s fully vaccinated population, according to data from the Centers for Disease Control and Prevention.

Boosters are the latest X-factor for travelers, who have had to negotiate flight delays, closed borders and other issues in the past two years as the world adjusted to a deadly virus. Whether it is getting on an airplane or trying to get into venues such as restaurants and museums, those traveling should expect the rules of entrance to continue to move for the foreseeable future, says Myron S. Cohen, director of the Institute for Global Health and Infectious Diseases at the University of North Carolina at Chapel Hill.

“We’re building an airplane while we’re flying,” Dr. Cohen says. “Different countries are going to do different things. If I felt I had to travel, I would do my very best to have as many doses of the vaccine as was permissible.”

Amid a surge in cases, some countries are handing out second booster shots. In Israel, early data suggest a fourth vaccine dose can increase antibodies against Covid-19, but not enough to prevent infections from Omicron. WSJ explains. Photo composite: Eve Hartley/WSJ

On boosters, travelers should expect increased requirements to be the norm in 2022, says Marc Casto, a president of travel agency Flight Center Travel Group.

“Those that do not will likely be subject to quarantine along with more rigid and frequent testing,” he says. He says his clients in the Americas have been more likely to book trips to destinations where a higher percentage of the population is vaccinated and boosted.

The American Society of Travel Advisors is seeing people who would otherwise travel abroad modifying their plans in significant numbers and choosing to travel within the continental US instead because of impending booster requirements, Chief Executive Zane Kerby says.

“Requiring boosters adds to the hassle factor, and people are just tired of the paperwork. They’re tired of the waiting. They’re tired of not knowing if they’re actually going to go on the trip until 12 to 24 hours before the trip happens,” Mr. Kerby says.

For those still looking to travel, here are some popular destinations with booster requirements:
