Third (Additional) Vaccine Doses

Third vaccine doses are available only for those who received Moderna or Pfizer vaccine, and whose last shot was at least 28 days ago.

Third vaccine doses are available for those six months and older who have a weakened immune system.

You can schedule an additional vaccination dose at a county health department or through your doctor or regular health care provider.
