If further confirmed, the new findings suggest that a preventive intervention for dementia is already close at hand.In a further finding, the study showed that protection against dementia was much more pronounced in women than in men. This could be due to sex differences in immune response or in the way dementia develops, Geldsetzer said. Women on average have higher antibody responses to vaccination, for example, and shingles is more common in women than in men.Whether the vaccine protects against dementia by revving up the immune system overall, by specifically reducing reactivations of the virus or by some other mechanism is still unknown.[MEDIA=youtube]unnePZUqi1o[/MEDIA]</blockquote>
