Experimental: mRNA-6231 Dose Level 2 - In the single dose part of the study (Sentinel and Expansion Cohorts), each participant will receive 1 dose of Dose Level 2 of mRNA-6231 by subcutaneous injection on Day 1.

In the repeat dose part of the study (Sentinel and Expansion Cohorts), each participant will receive up to 3 doses of Dose Level 2 of mRNA-6231 once every 2 weeks.

Experimental: mRNA-6231 Dose Level 3 - In the single dose part of the study (Sentinel and Expansion Cohorts), each participant will receive 1 dose of Dose Level 3 of mRNA-6231 by subcutaneous injection on Day 1.

In the repeat dose part of the study (Sentinel and Expansion Cohorts), each participant will receive up to 3 doses of Dose Level 3 of mRNA-6231 once every 2 weeks.
