The Washington State Department of Health says it will immediately start offering booster doses of the Pfizer-BioNTech Covid-19 vaccine to certain people after recommendations from the US Food and Drug Administration and other groups, reports AP.

State health officials said that at least six months after completing the primary Pfizer vaccine series, people age 65 and older; people age 18 and older living in a long-term care setting; and people age 50 to 64 with underlying medical conditions or at increased risk of social inequities, should receive a booster dose of the Pfizer vaccine.

Officials say there are not yet recommendations for people who received the Moderna or Johnson & Johnson Covid-19 vaccines.
