Association of MMR and Tdap vaccination history with hospitalization and progression to ICU stay or death from SARS-CoV-2 infection

(A–C) Overlap propensity score-weighted analysis odds ratios with 95% confidence intervals presented for the whole cohort (A) and then stratified by gender (B) and age (C). The upper limit of the 95% confidence intervals for the adjusted odds ratios was less than 1 for both risk for hospitalization and risk for transfer to the ICU or death for patients with a history of prior vaccination for either MMR or Tdap.
