Dementia after vaccination

Mr. Biden has had 6 covid shots and covid infection 3 times.

Results, Increased incidence of MCI and AD in vaccinated individuals,

particularly those receiving mRNA vaccines,

within three months post-vaccination.

mRNA vaccine group

AD, Odds Ratio: 1.225

p = 0.026

MCI, Odds Ratio: 2.377

p less than 0.001

No significant relationship was found with vascular dementia or Parkinson's disease.

Background

Concerns about vaccine side effects, particularly potential links to neurodegenerative diseases such as Alzheimer's disease (AD).

Aim

This study investigates the association between COVID-19 vaccination and the onset of AD,

and it’s prodromal state, mild cognitive impairment (MCI).

Design

A nationwide, retrospective cohort study

Korean National Health Insurance Service.

Data recorded 3 months after vaccination

Methods

analyzed data from a random 50% sample,

aged 65 and above,

n = 558,017.

Vaccinated group

Unvaccinated group

Patients with vascular dementia or Parkinson's disease served as controls.

Conclusions

Preliminary evidence suggests a potential link between COVID-19 vaccination,
