Clinical Trial Summary

The primary objectives of the study are: - To describe the safety profile of all participants in each age group and each study intervention group up to 12 months post-last dose. - To describe the neutralizing antibody profile at Day 1, Day 22, and Day 36 of each study intervention group. The secondary objectives of the study are: - To describe binding antibody profile from Day 1 to Day 387 of each study intervention group. - To describe the neutralizing antibody profile from Day 91 to Day 387 of each study intervention group. - To describe the occurrence of virologically-confirmed coronavirus disease-2019 (COVID-19)-like illness and serologically-confirmed SARS-CoV-2 infection. - To evaluate the correlation/association between antibody responses to SARS-CoV-2 messenger RNA (mRNA) vaccine and the risk of virologically-confirmed COVID-19-like illness and/or serologically-confirmed severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection.


Clinical Trial Description

The duration of each participant's participation in the study was approximately 365 days post-last injection: approximately 386 days duration for participants receiving 2 injections and approximately 365 days duration total for participants receiving a single injection. ;
