Routine vaccines may cut dementia risk–experts have startling hypothesis on how
Experts are exploring a hypothesis that routine vaccines may reduce the risk of dementia by training a previously untrainable part of the immune system. Vaccines for various diseases, including shingles, have shown a strong connection to lower dementia risks. This emerging understanding could enhance our knowledge of immune systems and open new avenues for dementia treatment and prevention.
- ▪Routine vaccines have been linked to lower risks of dementia.
- ▪Vaccines against shingles show one of the strongest connections to reduced dementia risk.
- ▪The hypothesis suggests that vaccines may train the innate immune system, which was previously thought to be untrainable.
