Brief summary

The main goal of this observational study is to describe the health and economic outcomes associated with use of the Moderna mRNA-1345 vaccine.

Detailed description

This study will evaluate real-world data (RWD) and data from eligible United States (US) based participants from Study mRNA-1345-P301 (NCT05127434) for additional health and economic outcomes such as hospitalizations, healthcare resource utilization, disease exacerbations, and costs, associated with usage of the mRNA-1345 vaccine. The results from the current study (mRNA-1345-P901) are intended to complement the results from the mRNA-1345-P301 study. No interventions will be administered during the current study (mRNA-1345-P901).
