Stronger flu shot linked to nearly 55% lower Alzheimer's risk
The Brief
- Researchers at UTHealth Houston analyzed nearly 200,000 adults aged 65 and older.

- The study reports an association, so the sources do not establish that the vaccine causes the lower risk.
Why it matters
The finding suggests a possible link between vaccine dose and Alzheimer's risk in older adults, which could inform future research on preventive strategies. It is an association from one study, so it should not yet change individual medical decisions.
