This may be a good place to mention that a huge study [0] conducted over 6 years with tens of thousands of US Veterans Administration patients found that having a recent Tdap vaccination predicted a 40% lower incidence of dementia. This was confirmed with an independent cohort.

You hardly need any reason to go get your Tdap booster. Any faint possibility that it might stave off dementia ought to be enough by itself. Get your shingles vaccine, too, while you're there. And, get prescribed some valacyclovir: studies in Asia have shown that had a desirable effect, with no risk.

Some internet service providers, particularly in UK, fail to provide service where Sci-hub is involved. You may need a VPN. Or, contact someone at a university (library staff are usually eager to help) and get them to retrieve the article by the usual means. Or, a regular internet search on the DOI gets you to the regular publisher, who will be little help, but e-mailing an author identified there will likely get you a PDF.

Academic journal publishers are the scum of the earth.
