A Study of the Safety of and Immune Response to Varying Doses of a Vaccine Against COVID-19 in Healthy Adults

Summary

The purpose of this study is to assess the safety, reactogenicity and immune response of a self-amplifying mRNA (SAM) lipid nanoparticle (LNP) platform with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Spike antigen (CoV-2 SAM \[LNP\] vaccine) in ascending doses when administered intramuscularly (IM) on a 0,1-month schedule to healthy adults 18 to 50 years of age. There will be no administration of escalated doses of the study vaccine.
