| Brief Summary | Multicenter, randomized, blind, placebo-controlled clinical study of III phases on the assessment of preventive efficiency, safety and immunogenicity QazCovid-in®-vaccine against COVID-19 in healthy adult volunteers | |||||||||
| Detailed Description | The main objective of the study is to prove the superiority of the QazCovid-in®-vaccine inactivated against COVID-19 in comparison with placebo in terms of seroconversion (the proportion of persons with a fourfold or higher increase in antibody titers to SARS-CoV-2) on the 21st, 42nd day, 90th and 180th days after vaccination. To evaluate the immunogenicity of the QazCovid-in® vaccine inactivated against COVID-19 versus placebo. Evaluate vaccine efficacy. Evaluate the safety of vaccine versus placebo. |
