(Salem, OR) -- The Western States Scientific Safety Review Workgroup is recommending older and at-risk individuals receive the Pfizer COVID-19 vaccine booster shot six months after getting fully vaccinated. The workgroup released the recommendation late last week, allowing the booster to be given in Oregon, Washington, California, and Nevada. It's recommended that people older than 65, people in long-term care facilities, and people 50 to 64 years old with underlying medical conditions get a third dose of the Pfizer vaccine. A booster shot will also be available to people between 18 and 64 if they have underlying medical conditions or work in a job where they're at higher risk of getting COVID-19.
