Herpes zoster vaccine appears to prevent dementia – Spectrum of Science

The shingles vaccination appears to reduce the risk of dementia. This is the conclusion of a working group led by Markus Etting of the Heidelberg Institute for Global Health based on data from unvaccinated people in Wales and those vaccinated with the live Zostavax vaccine. Like the team in beta It was reported that people in the group with a vaccination rate of about 50 percent were approximately one-fifth less likely to develop dementia than the unvaccinated comparison group. The finding supports the hypothesis that the chickenpox virus, which causes shingles, is involved in the development of dementia.
