RSV still spreading, prompting states to extend immunization period
Respiratory syncytial virus is spreading later into spring than usual, prompting multiple states to extend infant and toddler immunization windows.
Respiratory syncytial virus (RSV) is continuing to spread later into the spring than usual, driving most states to extend the window for RSV immunizations for eligible infants and toddlers. RSV is a common respiratory virus that typically causes mild cold‑like illness but can be more severe in very young children and the elderly. The extended immunization period is being used to protect vulnerable populations as the usual seasonality appears delayed this year.
