A Surprising Finding Leads to an RSV Vaccine Breakthrough

(Bloomberg) While the world is still focused on fighting Covid, another nasty respiratory virus is on the march. It’s called RSV, which stands for respiratory syncytial virus, and it sends thousands of young children and elderly adults to the hospital every year.  There isn’t yet a vaccine for RSV, but that could soon change. RSV shots from Pfizer and GSK have shown promising results in big trials for elderly adults. In another trial, the Pfizer shot protected babies from severe RSV lung illness after it was given to pregnant women. Meanwhile, Sanofi and AstraZeneca have a long-acting RSV antibody for infants that recently got approval in Europe.
