The recommended vaccine marks the second option for concerned parents, the first being lab-made antibodies given to babies younger than 8 months before their first RSV season.
Most infants will likely only need protection from one — either the mom’s vaccine or the antibodies — but not both, according to CDC Director Dr. Mandy Cohen.
There is no head-to-head study that answers which is more effective, and no published research on how safe it is to give both. They are both expensive but that depends on the recipients’ health insurance status.
RSV, or respiratory syncytial virus, is a common cause of cold-like symptoms. A surge last year filled hospitals with wheezing children, but far more U.S. seniors are hospitalized and die from the virus.
Two new vaccines were recently approved for Americans age 60 and older. There isn’t a vaccine for children.
