FDA approves Pfizer Comirnaty XFG COVID vaccine August 27 2026

Comirnaty XFG targets the XFG variant lineage and is already shipping, but approval covers only seniors 65-plus and ages 5-64 with a risk condition.

FDA approved Comirnaty XFG on August 27, 2026, targeting the XFG variant and its sublineages.
Approval covers only seniors 65-plus and ages 5-64 with a qualifying risk condition, not everyone.
One of three FDA vaccine updates this week for the 2026-2027 season, alongside Spikevax and mNEXSPIKE.

Why it matters: An annual strain update for the old and the sick is not three new vaccines for everyone.
