This project was a Phase III, randomized, modified double-blind clinical trial (Study Code: VAT00008) conducted by Sanofi to evaluate the efficacy, safety, and immunogenicity of SARS-CoV-2 Adjuvanted Recombinant Protein Vaccines in adults aged 18 and older. The study investigated both monovalent and bivalent vaccine formulations administered as a primary series or booster dose to protect against COVID-19. Ultimately, the research aimed to assess the vaccines' ability to prevent symptomatic infection and provide robust immune responses against emerging SARS-CoV-2 variants of concern
To evaluate the efficacy of two doses of SARS-CoV-2 recombinant protein vaccines (with adjuvant) in preventing symptomatic COVID-19 infection in SARS-CoV-2 naive adults.
To evaluate the non-inferiority or superiority of the immune response elicited by the vaccine formulations compared to a control or reference standard.
To evaluate the safety and tolerability profile of the vaccine candidates following each injection (including solicited local and systemic reactions, unsolicited adverse events, and serious adverse events).
To assess the efficacy of the vaccines against severe COVID-19 infection, hospitalization, and death.
To evaluate vaccine efficacy against specific emerging SARS-CoV-2 variants of concern.
To evaluate the immune response following a booster dose in individuals previously primed with authorized COVID-19 vaccines or natural infection.
Efficacy of a monovalent (D614) SARS-CoV-2 recombinant protein vaccine with AS03 adjuvant in adults: a phase 3, multi-country study
