Aug 16, 2024, 11:00 AM

Pfizer has announced positive results from a trial of its RSV vaccine, Abrysvo, which demonstrated a strong immune response in immunocompromised adults. The late-stage trial involved four groups of adults aged 18 and older with compromised immune systems, including those on dialysis, with lung cancer, on immunotherapy, and who had received solid-organ transplants. The vaccine generated robust antibodies against RSV-A and RSV-B, showcasing its potential in protecting at-risk adults from severe RSV-related illnesses. This development is part of Pfizer's efforts to expand the reach of its RSV vaccine.
