The FDA has approved updated formulations of Comirnaty, Spikevax, mNEXSPIKE, and Nuvaxovid for the 2026-2027 COVID-19 vaccination season. The vaccines were revised to target the XFG variant, a descendant of the JN.1 lineage, following recommendations from the Vaccines and Related Biological Products Advisory Committee.

Distribution to pharmacies, hospitals, and clinics is expected within days of approval.
