Four Updated COVID Vaccines Cleared for Fall Rollout, Targeting Omicron XFG

The FDA has approved four updated COVID-19 vaccines from Pfizer (Comirnaty), Moderna (Spikevax and mNexspike) and Novavax (Nuvaxovid) that target the Omicron XFG variant; Moderna’s mNexspike uses a lower 10 µg dose. Vaccines are being shipped to clinics and pharmacies; the guidance is to vaccinate unvaccinated or high‑risk individuals (65+ or with certain conditions). For timing, aim to receive the shot around October to cover the winter season, bearing in mind protection wanes after about six months. If recommended, the vaccine is usually free with insurance, while uninsured Utahns can use the Utah Vaccines For Adults program to obtain vaccines cheaply.
