Number of Participants Reporting Systemic Solicited Adverse Events Signs and Symptoms
Measured for 7 days after each injection in Parts A and B and 14 days after each injection in Part C, up to Month 6

Graded according to the Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events, Version 2.1 \[July 2017\]. The maximum grade observed for each symptom over the time frame is presented

Number of Participants With Local Laboratory Values Meeting Grade 1 AE Criteria or Above
Measured through Month 8 (Part A without second boost) or Month 12 (Part A with second boost, Part B, Part C)

For each local laboratory measure meeting Grade 1 AE criteria (Mild) or above as specified in the DAIDS AE Grading Table, counts of severity were presented by treatment group and timepoint for the overall population

Number of Participants Reporting Unsolicited Adverse Events (AEs)
Measured through Month 14 (Part A without second boost) or Month 18 (Part A with second boost, Part B, Part C)

The number (percentage) of Participants Reporting Unsolicited Adverse Events (AEs) was summarized by arm

Number of Participants With Early Discontinuation of Vaccinations and Reason for Discontinuation
Measured through Month 2 (Part A without second boost) or Month 6 (Part A with second boost, Part B, Part C)

The number (percentage) of participants with early discontinuation of vaccinations and reason for discontinuation was summarized by arm

Number of Participants With Early Study Termination and Reason for Early Study Termination
Measured through Month 8 (Part A without second boost) or Month 12 (Part A with second boost, Part B, Part C)

The number (percentage) of participants with early study termination and reason for early study termination was summarized by arm
