People who are immunocompromised should follow current prevention measures (including wearing a mask, staying 6 feet apart from others they don’t live with, and avoiding crowds and poorly ventilated indoor spaces) regardless of their vaccination status.
If someone who has been fully vaccinated suspects that they may have been exposed to someone who is suspected to have COVID-19, or has been confirmed to have it, to get tested 3-5 days after exposure, and to wear a mask in public indoor settings for 14 days or until they receive a negative test result.
At the educational level, the CDC recommends universal indoor masking for all teachers, staff, students, and visitors to schools, regardless of what their vaccination status is.
While COVID-19 infections generally happen only to a small proportion of people who have been fully vaccinated, preliminary evidence suggests that those who do become infected with the Delta variant may be fending off the coronavirus fairly well, but they can also spread the virus to others.
