People fully vaccinated against covid-19 can travel again if they take precautions such as wearing a mask and respecting social distancing, US health authorities said on Friday.

To travel within the country, those who have received the vaccines they will not have to quarantine or undergo a covid-19 test after traveling, said the Centers for Disease Control and Prevention (CDC).

Nevertheless, International travelers heading to the United States must test negative for COVID-19 before boarding the plane and undergo a test after arrival.

Additionally, they will need to be quarantined if required by local authorities, the CDC said in a statement.

Meanwhile, vaccinated travelers traveling abroad may leave the country without a negative test, unless requested by the authorities of the destination country.

These new recommendations from the CDC come at a time when travel has recovered strongly in the United States, encouraged in particular by the Easter holidays and spring break.

A person is considered fully vaccinated two weeks after the last recommended dose of the vaccine. For two-dose vaccines, this occurs after the second.

“More than one in five adults is already fully vaccinated” in the United States, said Rochelle Walensky, director of the CDC.
