FDA approves second COVID-19 booster for seniors.

The FDA has authorized an additional booster dose of the Pfizer or Moderna COVID-19 vaccines for older Americans and people with weak immune systems. The FDA also announced that anyone getting a Pfizer or Moderna dose, whether it’s a booster or their first-ever vaccination, will get the newest formula, not the original shots. Those 65 or older can opt to roll up their sleeves again for another booster as long as it’s been at least four months since their first dose of the so-called bivalent vaccine that targets omicron strains. Most people who are immune-compromised can also choose that extra spring booster at least two months after their first, with additional doses in the future at the discretion of their physician.
