In the past, eligibility for a shingles vaccine in Wales was date of birth. Those born before September 2, 1933 were excluded. On the other hand, Welsh people who were born afterwards were entitled to be vaccinated.
These circumstances now offered ideal research conditions for a study that examined the connection between dementia and shingles vaccinations. Scientists from the Universities of Heidelberg, Mainz and Vienna came together for this. Researchers from Stanford University in California also took part.
Striking causal relationships between shingles vaccination and dementia
With a sample of over 290,000 people and data on vaccinations, medical examinations and death certificates, they discovered striking causal relationships. A diagnosis of dementia was reduced by 19.9 percent with a shingles vaccination over the following seven years. And the vaccine had a much stronger effect on women than on their male contemporaries.
The conclusion of the researchers: “Our results strongly indicate an important role of the varicella-zoster virus in the development of dementia”.
According to “Focus”, the test results have not yet been checked by a specialist board. Nevertheless, they allow a positive outlook on the future of dementia research.
