Study Population

The study population was selected from participants who were registered to receive the mRNA-1273 vaccine in the Pep Up vaccination history Database whose start date of observation in the claim database was within 6 months or more before vaccination with mRNA-1273 vaccine, and those who met the definition of underlying disease based on the claim data for 6 months.

You may qualify if:
