Guam is offering COVID-19 vaccinations to American expats in Japan and other Asian countries, where vaccine rollouts are lagging behind the U.S. and most developed nations.

But if they are expecting a relaxing vacation that comes with vaccination, they may be disappointed. Travelers to the Pacific island, which has travel alerts in place and a rising number of coronavirus cases, will face challenges including quarantine protocols.

Launched earlier this month, the vaccination program — called “Air V&V,” using the initials of vaccination and vacation — aims to encourage Americans in Asia who may not have the same access to vaccines as those back home to visit Guam to get their COVID-19 shots.
