Dr. Anthony Fauci, infectious diseases expert and head of the National Institute of Allergy and Infectious Diseases, now says that people should remain masked in all indoor settings unless they are confident that the people around them have been fully vaccinated.
Fauci also advised people eligible for a COVID-19 vaccine booster shot to get one before holiday celebrations.
During Thursday’s MSNBC broadcast of “All In with Chris Hayes,” Fauci said that Americans should remain masked unless they know for sure that people they are around have been fully vaccinated.
