Clinical Trial Summary

The purpose of this study: to assess the safety, tolerability and immunogenicity of the drug "Gam-COVID-Vac", a solution for intramuscular injection, at various times after vaccination in volunteers over 60 years of age

Description:

An open-ended prospective non-randomized study involving volunteers over the age of 60. The study will include 110 volunteers. who will receive the test drug according to the prime-boost scheme: the introduction of component 1 will be carried out on the 1st day, and component 2 - on the 21st day of the study. Outpatient monitoring will be performed during 4 visits: on the 7th, 14th, 28th, and 42nd days after the vaccine administration Also two visits will be performed in the phone contact mode for 90 and 180 days
