Clinical Trial Summary

Randomized, double-blind, placebo-controlled trial to evaluate safety and immunogenicity of intranasal "Gam-COVID-Vak" combined vector vaccine for the prevention of coronavirus infection caused by the SARS-CoV-2 virus. The duration of participation in the study for one subject will be 180±14 days after the first dose of vaccine, during which each subject will undergo a screening visit (within a week) and face-to-face visits according to the study plan. Intranasal vaccine administration will be done at day 1 vaccination visits and day 21±2 days on an outpatient basis. During the follow-up visits key vital signs will be assessed, and will collect data on changes in the state and well-being subjects from a previous visit. Subject data will be collected using electronic forms of individual registration cards, as well as with using questionnaires (diaries) filled by the subjects of the study. Immunogenicity will be assessed on day 1, 10, 28, 42 and 90 days. Humoral and cellular immune response will be evaluated.
