"These booster shots are free," President Biden said in remarks Wednesday afternoon encouraging people in the U.S. to get the shots when it's their turn. "It will be easy. Just show your vaccination card, get a booster. ... It will make you safer and for longer. And it will help us end the pandemic faster."
The timing of the move comes as something of a surprise. It was just a few days ago that the FDA and CDC recommended a third shot of the Pfizer or Moderna vaccine for a more limited population — people who are moderately to severely immunocompromised. The agencies made no mention then of imminently expanding this recommendation to the wider population.
