PRIMARY outcome

Timeframe: IM - Day 4, Day 8, Day 11, Day 15 and Day 366; IV - Day 1, Day 4, Day 8, Day 11, Day 15 and Day 366

Population: The PK set consisted of all participants who received AZD7442 and from whom PK blood samples were assumed not to be affected by factors such as protocol violations, and who had at least one quantifiable serum PK observation post-dose.

The serum concentrations of AZD7442 after a single IM or IV dose in pediatric participants were evaluated. The serum concentrations for each scheduled time point were summarized by route of administration using appropriate descriptive statistics, based on the (Pharmacokinetic analysis) PK analysis set.

SECONDARY outcome

Timeframe: Day 31 to Day 366 or early discontinuation visit (approx. 24 months)

Population: The SARS-CoV-2 nAb Evaluable Analysis Set (SES) consisted of all participants in the Safety Analysis Set from whom blood samples were assumed not to be affected by factors such as protocol violations, and who had at least one quantifiable serum titer observation post dose.

The pharmacodynamics of AZD7442 after a single dose in pediatric participants was evaluated. The result for overall vaccination status were presented.
