Following the Centers for Disease Control and Prevention’s approval of booster doses of Pfizer-BioNtech vaccinations for select populations, King County and the City of Seattle are ramping-up vaccination services to ensure free booster doses are available to everyone eligible, as well as continuing to serve those who are not yet fully vaccinated.

To help meet anticipated demand, King County, in conjunction with its vaccination partners, have already reopened or have expanded capacity at seventeen vaccination sites across King County. In addition, the City of Seattle will be opening three additional vaccination sites beginning in October to provide booster doses, as well as prime series vaccinations to those who are not yet fully vaccinated.

The CDC now recommends booster doses of Pfizer vaccine for people who have completed two doses of Pfizer at least six months ago and are:

65 years or older

Residents in long-term care facilities

50-64 years old who are at high-risk because of underlying medical conditions

The following people may also receive a booster shot of Pfizer vaccine at least 6 months after receiving two doses of Pfizer vaccine based on their individual benefits and risks:

18-49 years old who are at high-risk because of underlying medical conditions

18-64 years old in occupational or institutional settings that put them at high risk for COVID-19 (healthcare, schools, child care, homeless shelter, correctional facility)

King County’s comprehensive network of reopened and expanded partnership vaccination locations include sites in Auburn, Kent, Federal Way, Renton, Capitol Hill, Montlake, Harborview, downtown Seattle, Northwest Hospital, Shoreline, Redmond, Bellevue, Eastgate and Snoqualmie. These are in addition to community health centers, primary care clinics and pharmacies across the county that are also providing vaccinations, including booster doses. All COVID-19 vaccinations are free of charge, and all King County vaccination partnership sites are Americans with Disabilities Act accessible and open to the public.

The City of Seattle will be opening three additional vaccination sites beginning in October that will host weekly clinics to increase access to vaccinations. Sites are expected to serve West Seattle, South Seattle and Central Seattle with partners, locations and hours announced in early October. The City of Seattle will also relaunch mobile teams to focus on delivering boosters to older adults.

The city and county currently have sufficient vaccine doses and vaccination supplies to serve everyone who is eligible.

Public Health is also working to ensure those eligible for booster doses who cannot access traditional vaccination clinics are able to receive them. Many long-term care facilities are partnering with pharmacies to provide booster doses to eligible residents. Public Health will work closely with facilities that may not have a pharmacy partner to connect them with vaccination services. Mobile vaccination teams will provide booster doses to people in-need who are homebound.

At this time, only the Pfizer vaccine has been authorized by the Food and Drug Administration and recommended by CDC for booster shots, and the current recommendation only applies to people who received the Pfizer vaccine as their primary vaccine series. Moderna and Johnson & Johnson vaccines are anticipated to be approved for booster doses, after the manufacturers submit data to FDA for review.
