CDC recommends third Covid-19 vaccine dose for certain immunocompromised people

Vaccine advisers to the US Centers for Disease Control and Prevention voted unanimously on Friday to recommend an extra dose of Covid-19 vaccine for some immunocompromised people, and the CDC director signed off on the recommendation almost immediately.

The US Food and Drug Administration gave emergency use authorization Thursday night for a third dose in certain patients who are likely to have had a poor immune response to two doses of either Pfizer's or Moderna's vaccine. There's not enough data to discuss the possibility for an extra dose of Johnson & Johnson's one-shot Covid-19 vaccine, the FDA said.
