A higher-dose flu shot could spare millions of older adults a hospital stay

Article excerpt

A high-dose flu vaccine containing four times the antigen of standard shots could prevent hundreds of thousands of hospitalizations among older adults annually, according to research published in JAMA Network Open. The study examined whether HD-IIV, already approved for adults 65 and older, reduces severe outcomes like hospitalization and death more effectively than conventional flu shots. Influenza typically causes mild symptoms but can turn serious for elderly people, young children, and pregnant women. The findings could reshape vaccination strategies for vulnerable populations, though broader adoption would depend on cost, supply, and clinical uptake.
