Breakthrough on Pfizer RSV Vaccine
FDA has granted Pfizer a breakthrough therapy designation for its respiratory syncytial virus (RSV) vaccine candidate, PF-06928316 or RSVpreF, and its use in preventing RSV-associated lower respiratory tract illness in infants from birth up to six months of age through active immunization of pregnant women. The designation is based on data from the company’s Phase 2b proof-of-concept study that is evaluating RSVpreF’s safety and immunogenicity in healthy pregnant women ages 18 through 49 years old and who were vaccinated between 28- and 36-weeks gestation, Pfizer says.
RSV is a contagious virus and a common cause of respiratory illness. It affects the lungs and breathing passages of an infected individual and can be potentially life-threatening for young infants, the immunocompromised, and older adults.
