The US Centers for Disease Control and Prevention (CDC) updated its travel guidance for fully vaccinated people on Friday, recommending that fully vaccinated people can travel at low risk to themselves.
The CDC said COVID-19 tests are won't be required for fully vaccinated people before or after they travel within the US - as long as those travelling wear masks on planes, buses, and trains.
Officials consider people fully vaccinated two weeks after they receive the last dose of their vaccine.
The United States continues to make progress in Covid-19 vaccinations, with 50 percent of Americans 65 and older fully vaccinated. "Vaccines can help us return to the things we love about life, so we encourage every American to get vaccinated as soon as they have the opportunity".
Vaccinated travelers can go overseas without getting a Covid-19 test before travel unless it is required by the worldwide destination, the new guidelines say.
Since early March, people have been allowed to gather with small groups from other households without wearing masks or physically distancing measures in place.
Meanwhile, fully vaccinated people do not need to self-quarantine after returning to the United States.
In its updated guidance, the agency still "recommends delaying travel until you are fully vaccinated, because travel increases your chance of getting and spreading COVID-19".
According to the state's travel advisory, all travelers should get tested one to three days before starting their journeys, and nonessential travelers should get tested three to five days upon arrival into California and self-quarantine for a full seven days after travel, even if their test is negative. Unvaccinated travelers should still get tested 1-3 days before domestic travel and again 3-5 days after travel.
