About

This study is a multicenter, randomized, double blind, controlled, phase III clinical trial (Immunobridging Study) to evaluate the immunogenicity and safety of Vaksin Merah Putih - UA SARS-CoV-2 (Vero Cell Inactivated) in healthy populations aged 18 years and above. Vaksin Merah Putih - UA SARS-CoV-2 (Vero Cell Inactivated) is an inactivated vaccine made of SARS-CoV-2 virus isolated from a patient in Surabaya, composed with aluminium hydroxy gel, tween 80, and L-histidine, and this study will be the first phase III in human.

Full description

This is a double blind randomized controlled trial - immunobridging study. There will be 2 groups in the study. One adult group (18 year-old and above) with 5 µg dose, and 1 control group using CoronaVac Bio Farma. Both vaccines will be administered with 2-dose schedule, intramuscularly. All cohorts will be followed for 6 months.

This study will have two interim and one full analysis The main focus is immunogenicity and safety or reactogenicity issues. Data Safety Monitoring Board will be commissioned for this study to evaluate safety data over the study period and to review any events that meet a specific study pausing rule or any other safety issue that may arise. They will review the blinded 7 and 28 days safety data following the first dose of vaccine, and then the 7 and 28 days after the second dose. The immunogenicity data will be evaluated until 6 months after the second dose

Sex: All

Ages: 18+ years old
