Since September 28, 2023 it has been the recommendation of the CDC to vaccinate pregnant women who are between 32 and 36 weeks pregnant during the RSV season (Sept to Jan) in order to provide some passive immunity to newborns through their mothers’ shared antibodies. This is similar to the protection afforded newborns by thier mothers’ taking the Tdap, Covid and Flu vaccines in pregnancy. Babies can’t get all their vaccines immediately after birth, and their immune systems often require multiple series of vaccinations to be given before they are fully immune. Mothers sharing their immunity in the early weeks of their babies lives helps to prevent many potentially life-threatening infections, particularly RSV, which is responsible for 90% of newborn hospitalizations. We encourage our patients to avail themselves of the Abrysvo vaccine at their local pharmacy if they fall into the appropriate age/seasonal range.
