The Food and Drug Administration has approved the first RSV vaccine for expectant mothers aimed at protecting their newborn babies.
Given during the third trimester of pregnancy, Pfizer's new shot – Abrysvo – protects infants from lower respiratory tract disease caused by RSV, or respiratory syncytial virus, through their first six months of life.
RSV is a common respiratory virus that usually results in mild symptoms, but can be serious in infants, young children and older adults. Each year, up to 80,000 children under 5 are hospitalized with RSV, according to the Centers for Disease Control and Prevention. That makes it the leading cause of hospitalization among infants.
