FDA Panel Backs First RSV Vaccine Given in Pregnancy

May 18, 2023


The first vaccine designed to protect infants against respiratory syncytial virus (RSV) by vaccinating their mothers during pregnancy has been backed by a panel of advisers to the U.S. Food and Drug Administration.

On Thursday the independent committee of experts voted unanimously that the Pfizer-made vaccine was effective, and 10-4 that there was adequate data on safety to move the vaccine to approval, the Associated Press reported.

The shot would be given to pregnant women at 24 to 36 weeks gestation. This should stimulate the production of maternal antibodies to RSV that would then pass through the placenta to the fetus.
