Study design details

• Main study objective:
  The overarching aim of this study is to characterize the safety of the Omicron-containing bivalent SARS-CoV-2 mRNA-1273 booster vaccine as used in routine clinical practice.
• Outcomes:
  Number of Participants With Adverse Events of Special Interest (AESI)
• Data analysis plan:
  Primary Cohort Analysis For each patient, a propensity score (PS) will be calculated to estimate the probability of receiving a dose of the elasomeran/davesomeran or andusomeran vaccine conditional on measured covariates. The PS will be calculated utilizing inverse probability of treatment weighting (IPTW).
