The director of the Centers for Disease Control and Prevention (CDC) on Friday suggested that the definition of what constitutes being “fully vaccinated” may change as boosters become more commonplace, echoing a move handed down several weeks ago by Israeli officials.

For now, in order to meet the CDC’s criteria for being “fully vaccinated,” one has to have two shots of either the Moderna or Pfizer COVID-19 vaccine, or one dose of Johnson & Johnson’s.
