Focus Feature: Best flu protection for seniors?

High-dose and adjuvanted flu vaccines provided better protection for those 65 and over than standard flu vaccine

A new study found that high-dose and adjuvanted flu vaccines boosted protection against flu symptoms and hospitalization for people 65 years and older during the 2022-2023 flu season compared to the standard flu vaccine. While seasonal variation exists, researchers expect that seniors will continue to benefit from the stronger flu vaccines in the coming season.
