Trial Design

1Treatment groups
Experimental Treatment
Group I: mRNA-1273Experimental Treatment1 Intervention
Part A: All participants (healthy participants and SOT participants) who were unvaccinated prior to enrollment will receive 2 intramuscular (IM) injections of 100 microgram (µg) mRNA-1273 on Day 1 and Day 29. All SOT participants who were unvaccinated prior to enrollment will be offered the opportunity to receive a third primary dose of mRNA-1273 at Day 85 as per the emergency use authorization (EUA) Fact Sheet available at the time of protocol finalization. SOT participants who were previously vaccinated with 2 doses of Moderna COVID-19 vaccine under the EUA prior to enrollment will receive Dose 3 on Day 1. Part B: All eligible participants from Part A will be offered to receive a 100 µg booster dose of mRNA-1273 who are at least 4 months from the last dose. SOT recipients who completed primary COVID-19 vaccination series under EUA (outside of the mRNA-1273-P304 study) will receive a 100 µg booster dose on booster dose Day 1.
