COVID-19 booster dose recommendations

Aug 18, 2021

On August 16, the CDC recommended a booster dose of mRNA vaccine (Pfizer or Moderna) for moderately to severely immunocompromised people, which includes people who are undergoing certain medical treatments or taking medications that reduce their immune response. For patients who fall in this group, the recommendation is to get an additional dose at least 28 days after the second dose is administered. 

Beginning this fall, the CDC expects to recommend a booster dose for all people who completed an initial series of Pfizer or Moderna vaccine, eight months following the second dose. 

Any booster dose received should be the same brand that was received initially. Your vaccination card includes the type and date of vaccine received, or you can get personal vaccination records through the Washington State Immunization Information System (WAIIS) at

A physician's order is not needed for COVID-19 vaccine or a booster dose. Use the Department of Health Vaccine Locator for more information on vaccine locations. 

At this time, the booster dose recommendation does not apply to the Janssen (Johnson & Johnson) vaccine.
