A Study of Ad26.COV2.S in Adults (COVID-19)

A Randomized, Double-blind, Placebo-controlled Phase 1/2a Study to Evaluate the Safety, Reactogenicity, and Immunogenicity of Ad26COVS1 in Adults Aged 18 to 55 Years Inclusive and Adults Aged 65 Years and Older

The purpose of the study is to assess the safety, reactogenicity, and immunogenicity of Ad26.COV2.S at 2 dose levels, administered intramuscularly (IM) as a single-dose or 2-dose schedule, with a single booster vaccination administered in one cohort in healthy adults aged greater than or equal to (>=) 18 to less than or equal to (<=) 55 years and in adults aged >= 65 years in good health with or without stable underlying conditions. The purpose of the study is also to assess the safety and reactogenicity of Ad26.COV2.S administered as ad hoc booster vaccination in healthy adults aged >= 18 to <= 55 years and in adults >= 65 years in good health with or without stable underlying conditions.
