Pfizer’s RSV vaccine, given during pregnancy, protects infants from severe illness

(Washington Post) Pfizer announced Tuesday that its maternal RSV vaccine, given during pregnancy, protected infants from developing severe symptoms during the first six months after birth — a critical window of vulnerability. The company plans to apply for approval of the vaccine before year’s end, with the hope that the shot could be the first vaccine to help protect infants against RSV — respiratory syncytial virus — as soon as next winter.
