The FDA has adopted a strategy to administer Covid-19 vaccines annually before winter waves, promoting co-administration with the flu vaccine to limit severe illness during peak seasons.
While seasonal flu reliably surges in winter, Covid-19's seasonality is unpredictable, with summer waves emerging consistently, complicating vaccine timing and release strategies.
Experts suggest it's crucial to receive a Covid-19 vaccine now to combat the ongoing summer surge, despite available vaccines targeting past strains rather than current ones.
Current vaccines may not adequately protect against evolving variants like JN.1 and KP.2, highlighting the need for timely updates to the vaccination strategy.
