Respiratory syncytial virus (RSV) is a leading cause of severe acute lower respiratory tract infections (LRTIs) among infants globally, and a prominent contributor to common non-severe infections that account for high volumes of antibiotic consumption. Researchers from the University of California, Berkeley, Novavax, Princeton University, and CDDEP conducted a study to assess if maternal vaccination against RSV could reduce antimicrobial prescribing among young infants.
