Clinical Trial Summary

The purpose of this double-blind, randomized, controlled study is to evaluate the efficacy, immunogenicity, reactogenicity and safety of an adjuvanted recombinant severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) trimeric spike (S)-protein subunit vaccine (SCB-2019) for the prevention of SARS-CoV-2-mediated COVID-19 in Participants Aged 12 Years and Older.


Clinical Trial Description

This study will assess the efficacy against COVID-19, immunogenicity, reactogenicity, and safety of CpG 1018/Alum-adjuvated SCB-2019 vaccine. The COVID-19 pandemic has resulted in high morbidity and mortality, caused major disruption to healthcare systems, and has had significant socioeconomic impacts. Currently, only limited treatment options are available against COVID-19 and accelerated vaccine development is urgently needed. Several COVID-19 vaccines were recently authorized in some countries, but the global supply is insufficient for pandemic control. Additional safe and effective vaccines for COVID-19 prevention would have significant public health impact. Placebo recipients will be offered two doses of SCB-2019 vaccine at defined points as part of the study. Adults participants who received SCB-2019 vaccine, will be given a third dose of the SCB-2019 vaccine at least 4 months after the second dose to assess the safety and efficacy of a booster (third) dose. ;
