5. Study Description

Brief Summary
The Middle East respiratory syndrome coronavirus (MERS-CoV) was identified in 2012 during the first Middle East respiratory syndrome (MERS) outbreak. MERS-CoV causes an acute lower-respiratory infection in humans, with a fatality rate of ~34.5%. The aim of the study is to assess the safety and immunogenicity of heterologous adenoviral-based vaccine against MERS - BVRS-GamVac-Combi.
Detailed Description
The study will include volunteers of both sexes, aged 18-55 years inclusive. The study will involve 268 (will receive the vaccine or placebo) healthy volunteers. At the first stage, it is planned: study the safety of component 1 - 40 volunteers and 4 spares * study the safety of prime-boost vaccination with component 1 and component 2 with an interval of 21 days in half and full dose - 40 volunteers and 4 spares * At the second phase, it is planned to study the safety and immunogenicity of the vaccine as part of a placebo-controlled randomized trial - 188 people, of whom 138 will receive the vaccine, and 50 will make up the control group of observation - they will be given a placebo. Data from 20 volunteers from the first phase who received the drug in selected dose will be included in the analysis of safety and immunogenicity of the second phase. Volunteers are replaced by spares before the introduction of the drug, if the volunteer took the drug, then the replacement is not performed. Any volunteer who received a dose of the vaccine will be considered as included in the study, the data available on it will be used in assessing the safety and tolerability of the drug.
