For decades, a successful vaccine for a little-known – yet contagious, and in some cases fatal – disease called respiratory syncytial virus (RSV) had eluded the global health community.

Today, a team at Pfizer is working to develop a vaccine that could be delivered to mothers during pregnancy and potentially provide protection against RSV. Dr. Yasmeen Agosti, who is part of this team, started her medical career as a pediatrician and knows firsthand the devastating impact of RSV on infants and their families.

“If we look at history, we can see the tremendous impact vaccines have had in preventing diseases like polio, tetanus and others,” says Yasmeen. “I’d like to see the same thing happen for RSV and other diseases.”
