Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
