Beyfortus® (nirsevimab-alip)
for Respiratory Syncytial Virus

Beyfortus (nirsevimab-alip) is used to protect babies under 1 year of age from serious RSV lung infections and may also be given to children up to 2 years old at risk of severe RSV disease through their second RSV season. It contains nirsevimab-alip, a long-acting monoclonal antibody that targets the RSV F protein, preventing the virus from entering cells and multiplying. Beyfortus provides passive protection during the RSV season to reduce the risk of severe lower respiratory infections caused by RSV.
