Experts urge early flu vaccination as cases rise ahead of peak season
Epidemiologists warn of an early flu wave and recommend getting the shot now, noting it takes two weeks to become effective.
National data indicate an uptick in influenza cases, leading public-health experts to suggest that October is an optimal time for vaccination. The flu shot requires about two weeks to reach full protection, and receiving it now helps cover the early wave and the later peak period. Vaccine effectiveness declines over time, so shots given in summer would be weaker by February.
Moderna's mRNA-based flu vaccine, mFlusiva, has received FDA approval for people aged 50+, and studies show it outperforms four other flu shots. Health authorities continue to recommend the vaccine for everyone six months and older, despite recent political attempts to alter childhood immunization guidelines.
Why it matters
Getting the flu shot early can prevent illness and reduce severe outcomes during the season's peak.
