About
This Phase III study is a global multicenter, randomized, double-blind,placebo controlled clinical trial to evaluate the efficacy, safety, and immunogenicity of therecombinant COVID-19 vaccine (Sf9 cells) in 40,000 participants aged 18 years and older who do not have a known history of SARS-CoV-2 infection but whose locations or circumstances put them at appreciable risk of acquiring COVID-19 or SARS-CoV-2 infection.
Full description
This Phase III study is a global multicenter, randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy, safety, and immunogenicity of the recombinant COVID-19 vaccine (Sf9 cells) in 40,000 participants aged 18 years and older who do not have a known history of SARS-CoV-2 infection but whose locations or circumstances put them at appreciable risk of acquiring COVID-19 or SARS-CoV-2 infection. All participants will receive three doses of either study vaccine or placebo on Day 0, Day 21, Day 42 in a ratio of 1:1.There will be two cohorts in the study: the efficacy-safety cohort and the efficacy-extended safety-immunogenicity cohort. The efficacy will be evaluated in all vaccinated participants,including population in the efficacy-safety cohort, the efficacy-extended safety immunogenicity cohort. All vaccinated participants will also be followed up to monitor incidence of SAEs, MAAEs and AESIs. The reactogenicity of the vaccine will be evaluated in the efficacy-extended safety-immunogenicity cohort. Approximately 3000 participants will be enrolled into the efficacy-extended safety-immunogenicity cohort. This cohort will undergo additional visits to collect immunogenicity data associated with receiving the recombinant COVID-19 vaccine (Sf9 cells) and to analyze the infection status.

Exclusion criteria
Exclusion criteria for the first dose
Note: Participation in COVID-19 treatment trials is allowed in the event of hospitalization due to COVID-19. The study team should be informed as soon as possible.
Note: Disclosure of serostatus post enrolment may accidentally unblind participants to group allocation. Participation in this trial can only be allowed if volunteers are kept blinded to their serology results from local/national serological surveys
Exclusion criteria for the second/third dose In this trial, the second/third dose vaccination may be terminated in some cases. These include systemic allergic reactions, severe hypersensitivity reactions, or intolerable grade 3 or higher adverse reactions after the previous vaccination/placebo. If these reactions occur, the participants should not continue to receive the second/third vaccination.
