Pfizer now hopes to tell U.S. regulators how well its COVID-19 vaccine works in the littlest kids by late May or early June. Pfizer is testing three extra-small doses of its vaccine in children under 5 after two shots didn’t prove quite strong enough.
Pfizer and its partner BioNTech asked U.S. regulators Tuesday to authorize an additional booster dose of their COVID-19 vaccine for seniors, saying data from Israel suggests older adults would benefit.
Pfizer on Tuesday asked the U.S. to authorize extra-low doses of its COVID-19 vaccine for children under 5, potentially opening the way for the very youngest Americans to start receiving shots as early as March.
U.S. health regulators on Wednesday authorized the first pill against COVID-19, a Pfizer drug that Americans will be able to take at home to head off the worst effects of the virus.
Most Americans should be given the Pfizer or Moderna vaccines instead of the Johnson & Johnson shot that can cause rare but serious blood clots, U.S. health officials said Thursday.
