New research shows vaccinating pregnant women helped protect their newborns from the common but scary respiratory virus called RSV that fills hospitals with wheezing babies each fall.
"Moms are always giving their antibodies to their baby," said virologist Kena Swanson, Pfizer's vice president of viral vaccines."The vaccine just puts them in that much better position" to form and pass on RSV-fighting antibodies. "My fingers are crossed," said Dr. William Schaffner, an infectious disease specialist at Vanderbilt University."We're making inroads."Here's a look at the long quest for RSV vaccines.
"For a period of 20 years, even though science was advancing, nobody wanted to go near development of an RSV vaccine," Schaffner said. It turns out that the immune system only forms effective RSV-fighting antibodies when it spots what's called the pre-fusion version of that protein, explained structural biologist Jason McLellan of the University of Texas at Austin.
