CDC releases new guidelines for those fully vaccinated

The COVID-19 pandemic has spread throughout the world. Individuals who travel may be at risk for exposure to SARS-CoV-2, the virus that causes COVID-19, before, during, or after travel. This could result in travelers’ spreading the virus to others at their destinations or upon returning home.

As part of a broader strategy aimed to limit continued new introduction of SARS-CoV-2 into U.S. communities, and emergence of new SARS-CoV-2 variants, all travelers should remain vigilant for signs and symptoms of COVID-19, and take recommended precautions to limit community spread after traveling from one location to another. CDC has issued requirements and recommendations to prevent travel-associated exposure to and transmission of SARS-CoV-2.

As vaccination efforts continue across the United States, the proportion of travelers who are fully vaccinated will continue to increase. Travel-associated transmission risk is likely to be substantially reduced among those fully vaccinated with an effective vaccine, although global circulation of SARS-CoV-2 variants of concern and vaccine performance against emerging variants, and global vaccination coverage remain a concern. As such, CDC has updated its guidance for fully vaccinated travelers to account for these considerations. The guidance is also updated to align with existing guidance for people who have recovered from COVID-19 in the previous 3 months.

Of note, in this guidance, “fully vaccinated” refers to individuals who are ≥14 days following receipt of the second dose in 2-dose series of a U.S. Food and Drug Administration (FDA)-authorized vaccine (mRNA vaccines), or ≥14 days following receipt of a single-dose FDA-authorized vaccine (Janssen).
