Last Wednesday, the FDA ordered Pfizer and GSK to add Guillain-Barre Syndrome (GBS) as a serious adverse event risk warning to both Pfizer’s Abrysvo and GSK’s Arexy Respiratory Syncytial Virus (RSV) vaccine labels.
RSV is the leading cause of respiratory infection in adults over the age of 60. Prior to 2023, the CDC has not published data on the incidence of RSV death in babies and children. In 2023, the CDC estimates that approximately 100 children under the age of 5 died from RSV. Despite these low numbers, the CDC recommends that pregnant women receive an RSV vaccine to ‘protect’ their baby from RSV.
