A new RSV shot for newborn babies has been approved in Europe. The European Commission says it has approved a new drug developed by Sanofi and AstraZeneca that's meant to protect babies from getting the respiratory virus. The drug is an antibody injection that's given to infants less than a year old to protect them against RSV before they get the virus. The shot has yet to be approved in the U.S. This development comes as an unusually high number of RSV infections are already pushing hospitals to capacity.
