The FDA has approved updated COVID-19 vaccines aimed at targeting recent virus strains, including potential variants expected in the upcoming winter months.
Pfizer and Moderna are set to distribute millions of doses of the updated vaccines following the FDA’s approval, with Novavax also anticipating the availability of its modified vaccine version soon.
The big picture: The Centers for Disease Control and Prevention has recommended this fall’s shot for all individuals aged 6 months and older, as immunity from prior infections or vaccinations may wane over time.
- The updated vaccine formulation is tailored to newer branches of omicron descendants, with Pfizer and Moderna shots targeting a subtype known as KP.2 that was prevalent earlier in the year, offering cross-protection against related variants like KP.3.1.1.
- Individuals who recently recovered from COVID-19 are advised to wait three months post-recovery before getting vaccinated to allow for waning immunity from the infection.
- People are permitted to receive both COVID-19 and flu vaccinations simultaneously for added convenience, although the optimal time for flu vaccination typically falls between late September and October, just before flu season traditionally ramps up.
