The Food and Drug Administration approved updated COVID-19 vaccines from Pfizer-BioNTech, Moderna, and Sanofi-Pasteur on August 27. The new vaccines target the XFG strain, a subvariant of JN.1. Pfizer and Moderna use mRNA technology, while Sanofi's vaccine uses a different platform.

The FDA-approved vaccines are authorized for adults aged 65 and older, as well as younger people with underlying health conditions increasing severe illness risk.

Uncertainty over insurance coverage for updated COVID-19 vaccines

The XFG strain currently accounts for approximately 40% of COVID-19 cases in the United States according to CDC data from July.
Moderna COVID-19 vaccine approval: eligibility criteria
