Travel Guidelines


MBL Sponsored Travel

The MBL continues to permit MBL-sponsored international and domestic travel, as well as non-essential personal travel. Any member of the MBL community who chooses to travel must follow Massachusetts travel guidelines for quarantining and other COVID-19 measures at the destination and upon their return to Massachusetts.

Returning from Travel

Members of the MBL community who travel out of state should abide by the Commonwealth of Massachusetts COVID-19 Travel Guidelines to identify states with varying levels of COVID-19 risk and associated requirements for quarantine, testing, masking, and social distance that may apply based on where individuals travel to/from and on vaccination status.

Visit the Centers for Disease Control and Prevention (CDC) Travel guidelines for information on domestic and international travel guidelines and restrictions. According to the CDC guidance for domestic travel, individuals who are fully vaccinated with an FDA-authorized vaccine can travel within the United States and do not need to get tested before or after travel unless their destination requires it and do not need to self-quarantine. The CDC has also issued guidance for international travel. Note that travel requirements to enter the United States changed on December 6, 2021. All air passengers, regardless of vaccination status, must show a negative COVID-19 test taken no more than 1 day before travel to the United States.

Please refer to the CDC for appropriate guidance at the time of your travel. Even vaccinated individuals can occasionally catch COVID-19, and international travel increases the risk of importing new variants, so please take extra care regardless of vaccination status and be sure to get tested if you develop any symptoms of COVID. Unvaccinated individuals should avoid nonessential international travel and must follow testing and quarantine rules based on your itinerary.
