Graded according to the Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events. Corrected Version 2.1, dated July 2017. The following symptoms are considered as systemic reactogenicity if the onset date was within the periods of assessment specified in the protocol: malaise and/or fatigue, myalgia, headache, nausea, vomiting, chills, arthralgia, and body temperature. The item Max. Systemic Reaction is the maximum of the individual systemic variables for a participant. It does not include temperature.

Severity definitions are found in The Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events (DAIDS AE Grading Table), Corrected Version 2.1, dated July 2017); For participants reporting multiple AEs over the time frame, the maximum severity grade is counted.

Serum HIV-1-specific IgG responses were measured on a Bio-Plex instrument using a standardized custom Luminex assay. The readout is background-subtracted mean fluorescent intensity (MFI), with background adjustment for an antigen-specific plate level control. For each sample, response magnitude is net MFI, defined as experimental antigen MFI minus reference antigen MFI. Net MFI less than 1 is set to 1. Samples from post-enrollment visits have positive responses if they meet three conditions: (1) net MFI greater than or equal to an antigen-specific response threshold (defined as the maximum of 100 and the 95th percentile of pre-vaccination net MFI), (2) net MFI values are greater than 3 times pre-vaccination net MFI, and (3) experimental antigen MFI values are greater than 3 times pre-vaccination MFI. Data are excluded if the blood draw date was outside the allowable window, a participant was HIV-infected, or the reference antigen exceeds 5000 MFI.

PBMC samples are stimulated with synthetic peptide pools or left unstimulated as a negative control. For each sample, T-cell subset, and peptide pool, response magnitude is % cells expressing markers after peptide stimulation minus % cells expressing markers after no stimulation. A contingency table is constructed to assess response: stimulation (peptide/none) vs. marker expression (yes/no). A one-sided Fisher's exact test is applied, testing if the number of cells positive for the marker is equal in the stimulated vs. unstimulated cells. A discrete Bonferroni adjustment is made over the peptide pools. Response is positive if p\<=0.00001. Data are excluded if the blood draw date was outside the visit window, the participant was HIV-infected, PBMC viability or T-cell count were low, or negative control was high.

Assessed by multiplex assay. Response to a virus/isolate in the TZM-bl assay is considered positive if the neutralization titer is above a pre-specified cutoff (one-half the lowest dilution tested). A titer is defined as the serum dilution that reduces relative luminescence units (RLUs) by 50% relative to the RLUs in virus control wells (cells + virus only) after subtraction of background RLU (cells only). The pre-specified cutoff is 10 for TZM-bl cells.
