Rochelle Walensky, the director of the Centers for Disease Control and Prevention, has signed off on a Food and Drug Administration recommendation that those who received the Moderna vaccine get a booster five months after their second shot instead of six, a CDC spokesperson said Friday.

Driving the news: The move comes just days after the FDA and the CDC made a similar recommendation for Pfizer-BioNTech vaccine recipients.

What they're saying: "Vaccination is our best defense against COVID-19, including the circulating variants, and shortening the length of time between completion of a primary series and a booster dose may help reduce waning immunity," said Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research.

  • "Today’s action also brings consistency in the timing for administration of a booster dose among the available mRNA vaccines. We encourage everyone to get vaccinated — it’s never too late to get your COVID-19 vaccine or booster."
