The Centers for Disease Control and Prevention (CDC) released guidance for fully vaccinated people, noting that they can gather indoors in small groups without masks or physically distance with other fully vaccinated people. The CDC says you’re considered fully vaccinated if it has been at least two weeks since you had the second shot in a two-shot series (i.e., the Pfizer-BioNTech or Moderna vaccines) or if it has been at least two weeks since you received the Johnson & Johnson vaccine. If you want to be really safe after getting the Johnson & Johnson vaccine, you’ll wait four weeks to consider yourself fully vaccinated, says Thomas A. Russo, MD, professor of medicine and chief of the Division of Infectious Diseases.
