Do common vaccines and infections affect Alzheimer's risk in older adults

Leveraging population-based human data to uncover mechanisms connecting Alzheimer's disease and common infections and facilitate vaccines repurposing for AD prevention

NIH-funded research Duke University · NIH-11158827

This project looks at whether past infections and routine vaccines in adults 65 and older are linked to changes in Alzheimer's risk.

What this research studies

Researchers will analyze large population health datasets and medical records from older adults to compare histories of infections and vaccinations with Alzheimer's-related outcomes. They will use advanced statistical approaches that act as a proxy for clinical trials to reduce bias and better mimic random treatment assignment. The work will account for genetic factors like APOE and other health and demographic variables to separate vaccine or infection effects from other risks. The team aims to identify existing vaccines that could be repurposed as candidates for preventing Alzheimer's in older people.

Who could benefit from this research

Good fit: Ideal candidates are adults aged 65 or older with accessible medical records or vaccination histories who can be represented in population-based datasets or recruited for follow-up studies.

Not a fit: People under 65, those without reliable medical or vaccination records, or individuals with non-Alzheimer's dementias may not directly benefit from this project.

Why it matters

Potential benefit: If successful, this work could identify already-approved vaccines that lower Alzheimer's risk and guide preventative measures for older adults.

How similar studies have performed: Prior observational studies have suggested links between some vaccines and lower dementia risk, but this project uses novel pseudo-randomization methods to strengthen causal interpretation.
