claim: exploratory analysis of immunization records highlights higher sars-cov-2 rates in individuals with recent non-covid-19 vaccinations
evidence_1: furthermore, age, race/ethnicity, and blood group stratified analyses reveal significantly lower sars-cov-2 rate among black individuals who have taken the pcv13 vaccine, with relative risk of 0.45 at the 5 year time horizon (n: 653, 95% ci: (0.32, 0.64), p-value: 6.9e-05).", "we find that polio, hemophilus influenzae type-b (hib), measles-mumps-rubella (mmr), varicella, pneumococcal conjugate (pcv13), geriatric flu, and hepatitis a / hepatitis b (hepa-hepb) vaccines administered in the past 1, 2, and 5 years are associated with decreased sars-cov-2 infection rates, even after adjusting for geographic sars-cov-2 incidence and testing rates, demographics, comorbidities, and number of other vaccinations.", 
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  "these findings suggest that additional pre-clinical and clinical studies are warranted to assess the protective effects of existing non-covid-19 vaccines and explore underlying immunologic mechanisms.")
