Shingles vaccine(s) and dementia: the only medical intervention to work faster than Tums
drvinayprasad.com • • health
Key Points:
- Observational studies on shingles vaccines and dementia face significant methodological challenges, including differences between vaccinated and unvaccinated groups, changing diagnostic criteria, and biases in medical records.
- Despite huge investments, there has been no truly effective treatment for dementia, which is a slow-progressing condition with poorly understood biology.
- Four recent papers claim near-instant reversal or prevention of dementia following shingles vaccination, reporting surprisingly rapid and large effects that conflict with established scientific understanding.
- The author suggests these claims are likely influenced by biases and low pretest probability rather than true vaccine effects, and calls for more rigorous randomized trials and better data transparency, such as Kaplan-Meier plots for mortality and dementia outcomes.
- Media coverage of these vaccine-dementia claims is criticized for lacking clinical trial expertise, underscoring the need for improved scientific communication and critical appraisal in health reporting.
