Merck's Enflonsia vaccine for respiratory syncytial virus won approval from the Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices.

A group of outside advisers to the US Centers for Disease Control and Prevention voted 5-2 to recommend use of a new shot that can protect babies from respiratory syncytial virus, adding an additional tool against the most common cause of hospitalization in infants.

The eight new ACIP members met for the first time June 25 after Kennedy fired all 17 original members of the committee June 9.
