Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: mRNA-1273Experimental Treatment2 Interventions
Part 1: Participants will receive 2 IM injections of mRNA-1273 at doses pre-specified for this study, on Days 1 and 29. Participants will be offered an optional BD of mRNA-1273 lower than the dose chosen for primary series, ≥6 months after Dose 2. After protocol amendment (PA) 9, participants who have not yet received a BD will be offered a BD with mRNA-1273.214. Part 2: Participants will receive 2 IM injections of mRNA-1273 at dose selected from Part 1 on Days 1 and 29. Participants (6 to <12 year) will be offered an optional BD of mRNA-1273 lower than the dose chosen for primary series, ≥6 months after Dose 2. After PA 9, participants who have not yet received a BD will be offered a BD with mRNA-1273.214. Part 3: Participants will receive 2 IM injections of mRNA-1273 on Days 1 and 29 as primary series then 1 IM injection as Dose 3, on Day 149 ≥3 months and ≤5 months after receipt of Dose 2 of primary series. All 3 injections will be administered at lower dose than that of Part 1.
Group II: PlaceboPlacebo Group3 Interventions
Part 2 only: Participants will receive 2 IM injections of mRNA-1273-matching placebo on Day 1 and Day 29. Participants (6 to <12 year old) will be offered an optional BD of mRNA-1273 at a dose lower than the dose that was chosen for the primary series for this age group, at least 6 months post-cross-over Dose 2. After PA 9, participants who have not yet received a BD will be offered a BD with mRNA-1273.214.
