Updated travel guidance

Dear Academic and Administrative Deans,

Earlier this month, the CDC changed its COVID rating levels for several countries and updated its guidance for Level 3 countries from “avoid nonessential travel to these countries” to “make sure you are fully vaccinated before traveling to these countries.” 

Following this guidance, Harvard is updating its own travel guidance: For travel beginning July 1 or later, Harvard-affiliated persons who are fully vaccinated may engage in Harvard-related travel, without a petition, to countries rated Level 1, 2, or 3 for COVID by the CDC. 

As before, persons are considered “fully vaccinated” two weeks after their final dose of a vaccine authorized by the US FDA or the World Health Organization. Travelers who are not vaccinated, or who wish to visit a country with CDC COVID Risk Assessment Level 4, must submit a petition to the Vice Provost for International Affairs seeking permission to travel. 

Please note that:

  • Vaccinated members of the Harvard community should submit proof of their vaccination to HUHS as soon as possible;
  • All travelers are urged to register their travel information with International SOS so that the University may contact them and provide assistance in case of emergency; and
  • Harvard’s normal travel policies for students continue to apply. 

We will forward this message to Deans of Students, the International Emergency Management Team, and various other administrators who have regular contact with student, faculty, and staff travelers. We encourage you to share it with department chairs, center directors, and others.
