Strong RSV Vaccine Data Lifts Hopes

A new study suggests vaccinating pregnant women protects their newborns from the common but scary respiratory virus called RSV. The virus is a nuisance for most healthy people but it can be severe for babies and older adults. Efforts to create a vaccine have failed for decades but some recent promising studies are raising hopes that one might finally be getting close. Pfizer reported preliminary results of its pregnancy vaccine Tuesday, a shot it also tested successfully in older adults. Rival GSK also has reported success with its vaccine version in seniors.
