Let’s be clear. The primary reason to be vaccinated against shingles is that two shots provide 90 percent protection against a painful, blistering disease that a third of Americans will suffer in their lifetimes ….

But other reasons for older people to be vaccinated are also emerging. …

In 21 studies involving more than 104 million participants in Europe, Asia and North America, vaccination against shingles was associated with a 24 percent reduction in the risk of developing dementia. Flu vaccination was linked to a 13 percent reduction. Those vaccinated for pneumococcal infection had a 36 percent reduction in Alzheimer’s risk.
