The Alexandria Health Department and other COVID-19 vaccine providers in the city are now offering booster shots to all adults. The Centers for Disease Control and Prevention expanded booster eligibility to everyone 18 and older for the Pfizer and Moderna COVID-19 vaccines on Nov. 19. A booster dose or Pfizer or Moderna should be at least six months after the second dose. "Mix and matching" of different COVID-19 vaccines are allowed, but residents may first consult with their health care provider. All COVID-19 vaccine doses are free. According to patch.com, "Previously, Pfizer and Moderna boosters were recommended for anyone 65 and older, adults living in long-term care facilities, adults with underlying health conditions, or adults at higher risk for COVID-19 exposure due to their work setting. Booster doses of the Johnson & Johnson COVID-19 vaccine were already recommended for all adults at least two months after the initial dose." As per patch.com, "The CDC recommended the boosters after scientific evaluation of safety data, vaccine effectiveness and the current state of the pandemic. In Alexandria, residents can find appointments with providers at vaccines.gov or sign up for Alexandria Health Department clinics. Booster appointments at health department clinics may be limited in the coming weeks due to a focus on newly eligible children ages 5 to 11."
