US FDA approves Pfizer's maternal RSV vaccine to protect infants
The U.S. Food and Drug Administration on Monday approved Pfizer's respiratory syncytial virus (RSV) vaccine for use in women during the middle of the third trimester of pregnancy to protect their babies. The approval allows the vaccine to be given to women 32 to 36 weeks into a pregnancy to prevent lower respiratory tract infection and severe disease in infants until they are six months old, the company said. An FDA panel of outside experts backed the safety and effectiveness of Pfizer's RSV vaccine for women in their second and third trimesters earlier in May.
