There is one clinical trial.
This clinical study will assess the safety, reactogenicity, and immunogenicity of 2 dose levels of mRNA-1273 SARS-COV-2 vaccine in adults 18 years of age or older.
Description: Seroconversion as measured by an increase of SARS-CoV-2-specific neutralizing antibody (nAb) titer either from below the limit of detection (LOD) or lower limit of quantification (LLOQ) to equal to or above LOD or LLOQ, or a 4-times higher titer in participants with pre-existing nAb titers.
Measure: Seroconversion as measured by an increase of SARS-CoV-2-specific neutralizing antibody (nAb) titer Time: Through 1 year post last vaccination
