I am not a vaccine fan, but I'm not so sure about this particular post. Grok's analysis: The post cites a video clip of epidemiologist Nicolas Hulscher claiming flu shots increase flu infection risk by 27% based on a 2025 Cleveland Clinic preprint, which observed higher positive tests among vaccinated employees but attributes this to testing biases rather than causation, per the study's authors and CDC data showing overall vaccine effectiveness of 40-60% against severe flu.
Hulscher also alleges a 50% higher dementia risk from flu shots, drawing from a misinterpretation of cohort studies; peer-reviewed research, including a 2022 JAMA analysis of over 500,000 adults and a 2026 NYT-reviewed meta-analysis, consistently links flu vaccination to a 13-40% reduced dementia risk through lowered inflammation and infection burden.
