There is a safe vaccine for pregnant women. It protects babies

The FDA has just approved a vaccine that can be administered to women in the third trimester of pregnancy.

The US has approved the use in pregnant women of a respiratory syncytial virus (RSV) vaccine that protects newborns from the dangerous infection.

The US Food and Drug Administration (FDA) has announced the approval of the Abrysvo vaccine, manufactured by Pfizer, for use in pregnant women. The vaccine was already approved for use in people aged 60 and older, but is now available for women in their third trimester. Medical professionals advise administering it between 32 and 36 weeks of pregnancy.

The vaccine prompts the pregnant woman's immune system to produce protective antibodies, which are then passed to the fetus through the placenta. Also, as with other vaccines administered during pregnancy, antibodies can be passed to newborns through regular breast milk and nutrient-rich colostrum. (Other vaccines recommended during pregnancy are influenza and pertussis)

"RSV is a common cause of illness in children, and infants are at greatest risk for severe illness that can lead to hospitalization. The approval provides an opportunity for health care providers and pregnant women to protect infants from this potentially life-threatening disease," said Dr. Peter Marks, Director of FDA's Center for Biologics Evaluation and Research.
