The Biden administration may scrap plans to expand eligibility for second boosters to younger adults. Instead, it's trying to speed up the next generation of boosters targeting the omicron variant.
Federal health officials are convening with outside advisers April 6 to talk about a vaccine plan, whether that's another booster in the fall, an omicron shot or one that targets more than one strain.
Health officials argue the protection of the COVID vaccine booster wanes over time and say some people need a second booster. But other infectious disease experts say three shots are enough for now.
People aged 50 and over could soon be eligible for a second Pfizer-BioNTech or Moderna COVID vaccine booster. The administration wants to offer the shots as immunity from the first booster is waning.
