Pfizer Inc. announced that the U.S. Food and Drug Administration (FDA) has approved ABRYSVO, the company’s bivalent RSV prefusion F (RSVpreF) vaccine, for the prevention of lower respiratory tract disease caused by RSV in individuals 60 years and older. ABRYSVO is unadjuvanted and composed of two preF proteins selected to optimize protection against RSV A and B strains and was observed to be safe and effective.
“A vaccine to help prevent RSV had been an elusive public health goal for more than half a century. FDA approval is a monumental step forward in delivering on Pfizer’s commitment to help alleviate the significant burden of RSV in higher-risk populations, which includes older adults,” said Annaliesa Anderson, Ph.D., Senior Vice President and Chief Scientific Officer, Vaccine Research and Development, Pfizer. “ABRYSVO will address a need to help protect older adults against the potentially serious consequences of RSV disease. We are extremely grateful to the clinical trial participants, study investigator teams and our dedicated Pfizer colleagues for their roles in making this vaccine available.”
The FDA’s decision is based on the data from the pivotal Phase 3 clinical trial (NCT05035212) RENOIR (RSV vaccine Efficacy study iN Older adults Immunized against RSV disease). RENOIR is a global, randomized, double-blind, placebo-controlled study designed to assess the efficacy, immunogenicity, and safety of a single dose of the vaccine in adults 60 years of age and older.

“This past RSV season demonstrated the serious consequences and potential health risks this virus poses for older adults,” said Edward E. Walsh, MD, Professor of Medicine, University of Rochester Medical Center, and principal RENOIR investigator. “FDA approval of ABRYSVO recognizes significant scientific progress, and importantly helps provide older adults potential protection against RSV and an opportunity to improve community health by helping prevent the disease.”
RSV is a contagious virus and a common cause of respiratory illness worldwide. The virus can affect the lungs and breathing passages of an infected individual, potentially causing severe illness or death. In the U.S., the burden RSV causes in older adults is considerable. The severity of RSV disease can increase with age and comorbidities, such as chronic obstructive pulmonary disease, asthma, and congestive heart failure.
