At least 34 babies were mistakenly given the respiratory syncytial virus (RSV) vaccine and one of those babies was hospitalized according to a study published today in Pediatrics.
Researchers from the Centers for Disease Control and Prevention (CDC) analyzed data from the Vaccine Adverse Event Reporting System (VAERS) for the RSV vaccines, which are not approved for children.
The researchers found 27 reports of the Pfizer RSV vaccine (Abrysvo) and seven reports of the GSK RSV vaccine (Arexvy) mistakenly administered to children under 2 between Aug. 21, 2023, and March 18, 2024.
“While rare, vaccine administration errors are known to occur and may increase after a new vaccine or product is introduced,” Dr. Pedro Moro, lead author of the study, told MedPage Today.
Both vaccines were first approved in May 2023 for people ages 60 and older. Pfizer’s Abrysvo was approved in August 2023 for pregnant mothers during part of their third trimester, targeting RSV prevention in babies.
