Interesting Research Letter in JAMA (Journal of the American Medical Association). This was in a large study of folks that compared the number of SARS-COV2 vaccinations with the occurrence of Long Covid:

Quote
The number of vaccine doses was associated with lower long COVID prevalence: 41.8% (95% CI, 37.0%-46.7%) in unvaccinated patients, 30.0% (95% CI, 6.7%-65.2%) with 1 dose, 17.4% (95% CI, 7.8%-31.4%) with 2 doses, and 16.0% (95% CI, 11.8%-21.0%) with 3 doses.

CI is confidence interval. You can just look at the percentages for the "average" number of people with Long Covid.

Conclusion is simple: Get at least the three vaccinations. Don't be an idiot. Long Covid sucks.

Educating anyone benefits everyone.
