An individual is only considered “fully vaccinated” if one of the following three scenarios applies to them:  

1) It has been more than two weeks but less than six months since they received the second dose of their primary Pfizer or Moderna vaccination series
2) It has been more than two weeks but less than two months since they received their primary Johnson & Johnson vaccine.
3) They have received their booster for Pfizer, Moderna, or J&J (no wait time). 

For individuals not currently eligible for a booster, they retain their fully vaccinated status even after the six month timeframe (two months for J&J) has passed. 

Individuals under the age of 18 are not required to receive a booster in order to retain their fully vaccinated status, even if they are eligible.
