The growing data that “routine vaccinations” may lower the risks of stroke, heart attacks, and dementia (of various etiologies)
In this time when Robert F. Kennedy, Jr is weakening our public health infrastructure in many ways (with particular emphasis on his baseless attacks on vaccines and research funding), growing attention is being found that routine vaccinations may significantly reduce the risks of developing dementia, strokes, and heart attacks. Similar reductions in various types of cancers, autoimmune diseases, and other types of illnesses have been known for some time.
The mechanisms are not clearly known at this time, but a likely reason is the reduction of inflammation from viral infections prevented by the vaccines.

The first link is to a meta-analysis regarding the protective benefits of common vaccines in the prevention of dementia. A “meta-analysis” is a type of review of the data of multiple other related studies. The aggregate data undergoes scrutiny of multiple reviewers to assess for applicability, biases, strength of the conclusions, etc. This type of review is very rigorous and represents a good review of the state-of-the-art. This is the most rigorous of the three articles—the lay reader should probably concentrate on the summary & conclusion sections to avoid getting lost in the technicalities.
The second link is a summary article of a very large recent study performed in South Korea and examines the protection from heart attacks, strokes, coronary artery disease, and congestive heart failure from the shingles vaccine.
The third is a general article regarding the benefits from vaccines that may not be so obvious.
