Outcome Measures

Primary Outcomes (1)

  • Superiority of the vaccine Ad5-nCoV to placebo by the level of seroconversion

    Proportion of subjects with four-fold and higher increment of anti-receptor-binding domain antibodies \[receptor-binding domain, RBD\] of S-protein SARS-CoV-2).

    Day 28 after vaccination

Secondary Outcomes (32)

  • Immunogenicity of the vaccine Ad5-nCoV compared with placebo (titer of SARS-CoV-2 antibodies)

    Day 14, 28 and after 6 months after vaccination.

  • Immunogenicity of the vaccine Ad5-nCoV compared with placebo (level of seroconversion)

    Day 14, 28 and after 6 months after vaccination.

  • Immunogenicity of the vaccine Ad5-nCoV compared with placebo (rise of SARS-CoV-2 antibodies)

    Day 14, 28 and after 6 months after vaccination.

  • Immunogenicity of the vaccine Ad5-nCoV compared with placebo (T-cell response)

    Day 14, 28 and after 6 months after vaccination.

  • Frequency of confirmed COVID-19

    Within 6 months after vaccination (except for COVID-19 cases within 14 days after vaccination)

  • +27 more secondary outcomes
