Pfizer announced today that in a study, its new vaccine protected infants from developing severe RSV symptoms during their most vulnerable first six months of life.
As RSV cases hit record highs and hospitals are pushed to capacity, finally, good news seems to be on the horizon. The first-ever RSV vaccine may be available to parents as early as fall 2023!that a large international study found giving moms-to-be the new RSV vaccine was nearly 82 percent effective at preventing severe cases of RSV in their babies’ most vulnerable first 90 days of life and 69.4 percent effective at preventing severe cases in the first six months.
The RSV virus typically causes mild, cold-like symptoms among most adults and older children. Still, it can result in severe complications for babies younger than 12 months as it spreads to the lower respiratory tract, causing pneumonia and bronchiolitis. But mom’s supercharged antibodies may be able to help.
But the new RSV vaccine won’t just help vulnerable newborns—it could also help protect elderly adults who are also at risk for severe complications. Immunization and new monoclonal antibodies could help prevent infections in more than three-quarters of the at-risk elderly population.
