The Centers for Disease Control and Prevention (CDC) has released updated mask guidance for individuals who have been fully vaccinated against COVID-19.

Individuals are considered fully vaccinated at least 2 weeks after they have received the second dose of a 2-dose series of the Pfizer-BioNTech or Moderna COVID-19 vaccine, or at least 2 weeks after receiving a single-dose of the Janssen COVID-19 vaccine.  

Fully vaccinated individuals no longer need to wear a mask outdoors, except in certain crowded settings and venues such as sporting events or live performances. Specifically, the CDC states that fully vaccinated people can go unmasked when:

  • Walking, running or biking outdoors with members of their household.
  • Attending a small outdoor gathering with fully vaccinated family and friends, as well as with unvaccinated individuals.
  • Dining at an outdoor restaurant with friends from multiple households.

The CDC continues to recommend fully vaccinated individuals take precautions in indoor public settings by wearing a well-fitted mask. Additionally, masks should continue to be worn when visiting indoors with unvaccinated individuals who are at increased risk for severe COVID-19 or with unvaccinated individuals from multiple households.

The full guidance can be found on the CDC website.
