The CDC just released its guidelines for those who have been fully vaccinated.
“For the purposes of this guidance, people are considered fully vaccinated for COVID-19 ≥2 weeks after they have received the second dose in a 2-dose series (Pfizer-BioNTech or Moderna), or ≥2 weeks after they have received a single-dose vaccine (Johnson and Johnson (J&J)/Janssen).”
The CDC has put out these guidelines for currently authorized vaccines for emergency use by the U.S. Food and Drug Administration. These are the Pfizer-BioNTech, Moderna, and Johnson and Johnson (J&J)/Janssen vaccines.
These guidelines will also apply to vaccines that have been authorized by the World Health Organization (e.g., AstraZeneca/Oxford).
