Outcome Measures
Primary Outcomes (2)
Number of Participants With First Case of SARS-CoV-2 RT-PCR-positive Symptomatic Illness
To estimate the efficacy of a single IM dose of AZD7442 compared to placebo for the prevention of COVID-19 prior to Day 183. Planned to be evaluated through Day 183, however, the number of events required for the primary endpoint was achieved 165 days after the study start date which is displayed in the primary efficacy row below. Final analysis is final data from the study based on the pre-planned 183 days of follow up for this endpoint.
165 Days for primary analysis, 183 days for final analysis
AEs, SAEs, MAAEs, and AESIs Post Dose of IMP
To assess the safety and tolerability of a single IM dose of AZD7442 compared to placebo
457 Days, Final analysis
Secondary Outcomes (5)
The Incidence of Participants Who Have a Post-treatment Response (Negative at Baseline to Positive at Any Time Post-baseline) for SARS-CoV-2 Nucleocapsid Antibodies.

Study Arms (5)
AZD7442
EXPERIMENTALApproximately 5150 participants will be randomized in a 2:1 ratio • Arm 1 (n=approximately 3433) will receive a single dose (× 2IM injections) of 300 mg of AZD7442
Placebo
PLACEBO COMPARATORApproximately 5150 participants will be randomized in a 2:1 ratio • Arm 2 (n=approximately 1717) will receive saline placebo
Sub-study AZD7442 Arm 1
EXPERIMENTALApproximately 500 participants will receive AZD7442 in the repeat dose sub-study. -Sub-study Arm 1 (\~ 12 month repeat dose interval): Participants who received AZD7442 300 mg IM on Day 1 of the parent study will receive a second dose of AZD7442 300mg IM on sub-study Day 1.
Sub-study AZD7442 Arm 2
EXPERIMENTALApproximately 500 participants will receive AZD7442 in the repeat dose sub-study. -Sub-study Arm 2(\~ 6 month repeat dose interval): Participants who received placebo on Day 1 of the parent study will receive their first dose of AZD7442 300mg IM on sub-study Day1 followed by a second dose on sub-study Day 183.
Sub-study AZD7442 Arm 3
EXPERIMENTALA subset of Arm 1 and Arm 2 participants who will receive additional doses of AZD7442, 600mg, at Day 183 and Day 366 of the sub-study.
Interventions
* Single dose (× 2IM injections) of 300 mg of AZD7442 on parent study Day 1. * Single dose (× 2IM injections) of 300 mg of AZD7442 on sub-study Day 1. * Single dose (× 2IM injections) of 300 mg of AZD7442 on sub-study Day 183. * Single dose (x 2IM injections) of 600mg of AZD7442 on sub-study Day 183 and Day 366
