ListOutcomeTime frameDescription
PrimaryNumber of Participants With Confirmed Human Immunodeficiency Virus (HIV)-1 Infections Diagnosed Between the Month 7 and Month 24 Visits (Per-protocol [PP] Set)From Month 7 up to Month 24Number of participants with a confirmed HIV-1 infections diagnosed between the Month 7 and Month 24 visits (PP set) was reported. The data represents the cumulative incidence of HIV-1 infections.
PrimaryNumber of Participants With a Confirmed Human Immunodeficiency Virus (HIV)-1 Infections Diagnosed Between the Month 7 and Month 30 Visits (PP Set)From Month 7 up to Month 30Number of participants with a confirmed HIV-1 infections diagnosed between the Month 7 and Month 30 visits (PP set) was reported. The data represents the cumulative incidence of HIV-1 infections.
SecondaryNumber of Participants With Solicited Local Adverse Events (AEs)Up to 7 days post each vaccination (dose) on Days 1 (up to Day 8), 84 (up to Day 91), 168 (up to Day 175), and 364 (up to 371)
Number of participants with solicited local AEs were reported. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. Solicited local AEs that included injection site pain/tenderness, erythema and swelling at the study vaccine injection site, are used to assess the reactogenicity of the study vaccine and are pre-defined local (injection site) and which were noted by participants in their participant diary for 7 days post vaccination (day of vaccination and the subsequent 7 days).
SecondaryNumber of Participants With Solicited Systemic Adverse Events (AEs)Up to 7 days after each vaccination (dose) on Days 1 (up to Day 8), 84 (up to Day 91), 168 (up to Day 175), and 364 (up to 371)
Number of participants with solicited systemic AEs were reported. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. Solicited systemic events included events such as fatigue, headache, nausea, and myalgia, for which participants were specifically questioned and which were noted by participants in their participant diary for 7 days post vaccination (day of vaccination and the subsequent 7 days).
SecondaryNumber of Participants With Unsolicited Adverse Events (AEs)Up to 28 days after each vaccination (dose) on Days 1 (up to Day 29), 84 (up to Day 112), 168 (up to Day 196), and 364 (up to 392)
Number of participants with unsolicited AEs were reported. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. Unsolicited AEs are all AEs for which the participants were not specifically questioned in the participant's diary.
SecondaryNumber of Participants With Adverse Events of Special Interest (AESIs)Up to 6 months after the last vaccination (up to Month 18)
Number of participants with AESIs were reported. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. Thrombotic events and/or thrombocytopenia (defined as platelet count below the lower limit of normal \[LLN\] range for the testing lab) were considered to be potential AESIs.
SecondaryNumber of Participants With Medically-attended Adverse Events (MAAEs)From Day 1 up to Month 40
Number of participants with MAAEs were reported. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. MAAEs are defined as AEs with medically-attended visits including hospital, emergency room, urgent care clinic, or other visits to or from medical personnel for any reason.
SecondaryNumber of Participants With Serious Adverse Events (SAEs)From Day 1 up to Month 40
Number of participants with SAEs were reported. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. An SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly/birth defect; suspected transmission of any infectious agent via a medicinal product or medically important.
SecondaryNumber of Participants Who Discontinued the Study or Study Intervention Due to Adverse Events (AEs)From Day 1 up to Month 40
Number of participants who discontinued the study or study intervention due to AEs were reported. An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.
SecondaryNumber of Participants With a Confirmed Human Immunodeficiency Virus (HIV)-1 Infections Diagnosed Over Time (Modified Intent-to-Treat [mITT] Set)Month 0 to 24, Month 0 to 30, Month 0 to 40Number of participants with a confirmed HIV-1 infections diagnosed over time (mITT set) were reported. The data represents the cumulative incidence of HIV-1 infections at specified intervals.
