TRIAL DESCRIPTION
Public title COVID-19 vaccine (ChAdOx1 nCoV-19) trial in South African Adults with and without HIV-infection
Official scientific title COVID-19: An Adaptive Phase I/II Randomized Placebo-controlled Trial to Determine Safety, Immunogenicity and Efficacy of Non-replicating ChAdOx1 SARSCoV-2 Vaccine in South African Adults Living Without HIV; and Safety and Immunogenicity in Adults Living With HIV.
Brief summary describing the background and objectives of the trial A Phase I/II, double-blinded, placebo-controlled, individually randomized trial to assess safety, immunogenicity and efficacy of the candidate Coronavirus disease (COVID-19) vaccine ChAdOx1 nCoV-19 in adults aged 18-65 years living with and without HIV in South Africa. The vaccine or placebo will be administered via an intramuscular injection into the deltoid muscle of the nondominant arm. A total of 2000 participants will be enrolled into the trial; 1950 HIV-uninfected and 50 people living with HIV. There will be 4 trial groups, group 1 (n=50; intensive safety & immunogenicity cohort, HIV negative), group 2a (n=250; safety, intense immunogenicity & efficacy), group 2b (n=1650; safety, immunogenicity & vaccine efficacy) and group 3 (n=50, intensive safety & immunogenicity cohort, HIV positive). Participants will be followed up for 12 months after enrollment.
