High-Dose Flu Shot Effective for Baby-Boomers – Precision Vaccinations

(Precision Vaccinations News)

According to a Medical News BriefbyEmilyHarris with The JAMA Network,observationaldatafrom more than 1.6 million people in the United Statessuggests that a high-dose vaccine may also be more effective than standard-dose vaccines for certain adults.

Reported in theNew England Journal of Medicine in December 2023, the Original Articleevaluated a recombinant vaccine that contains more than triple the amount of influenza hemagglutinin protein compared with standard-dose vaccines.

Flu cases were about 15% lower for people aged 50 to 64 who received the recombinant vaccine.

Because standard-dose vaccines only prevent up to 40% to 60% of influenza cases, decreasing the number of cases by an additional 15% would still provide a substantial public health benefit, especially during more severe influenza seasons, the researchers wrote.

As of December 31, 2023, the U.S. CDC reported that over155million egg, cell, and nasal-based influenza vaccines, which are generally available at local pharmacies, had been distributed this flu season.
