US opens Covid-19 booster doses to all adults
The U.S. is moving to open up COVID-19 booster shots to all adults, letting them choose another dose of either the Pfizer or Moderna vaccine. Regulators authorized broader use of the shots Friday, seeking to simplify what has been a confusing list of who's eligible. At an immunization practices meeting, Dr. Nirav Shah urged the Centers for Disease Control and Prevention panel to broaden their guidance.
