People who are fully vaccinated against the coronavirus do not need a booster shot at this time, the Food and Drug Administration and the Centers for Disease Control and Prevention said in a joint statement released Thursday evening.
The big picture: Pfizer is expected to seek authorization from the FDA to administer a third dose of the Pfizer-BioNTech vaccine after releasing initial results of a study that found that an additional shot was five to 10 times more effective at neutralizing the virus.
