RSV drugs FDA Kennedy safety vaccines children.

Federal health officials are reviewing the safety of two injectable drugs used to protect babies and toddlers from the RSV virus. The drugs from Merck and Sanofi are not vaccines. But officials under Health Secretary Robert F. Kennedy Jr. have recently been scrutinizing a number of childhood shots. A spokesperson for Kennedy said the FDA will evaluate the latest data and consider updating labeling on the drugs. RSV typically causes mild symptoms in healthy adults, but it can be life-threatening for the very young and old. In recent years, federal advisers have recommended the RSV shots for babies and toddlers facing their first RSV season.
