25 Mar 2025 RSV Season Ends March 31
As the respiratory syncytial virus (RSV) season draws to a close on March 31, 2025, we want to remind all healthcare providers of essential considerations regarding administering the RSV immunization, nirsevimab (Beyfortus).
End of RSV season:
Continue to administer doses of nirsevimab to eligible children through March 31, 2025. Do not administer doses of nirsevimab after April 1, 2025.
Do not discard unused immunizations:
If you have unexpired doses of nirsevimab at the end of this RSV season, do not discard them. These doses can be safely stored until their expiration date. Unexpired doses can be utilized when the RSV season resumes on October 1, 2025.
If your nirsevimab expires before October 1, 2025, please process a vaccine return after the expiration date.
If you need any assistance with your return, contact dphproviderhelp@phila.gov.
