Covid19 Clinical Trial
Official title:
An Open Study of the Safety, Reactogenicity and Immunogenicity of the Vaccine Based on Peptide Antigens for the Prevention of COVID-19 (EpiVacCorona), With the Involvement of Volunteers Aged 60 Years and Above (Phase III-IV)
The aim of the clinical study is to study the safety, reactogenicity and immunogenicity indicators of the EpiVacCorona vaccine, with the involvement of volunteers aged 60 years and above. The research tasks are to: - to evaluate the safety of the EpiVacCorona vaccine when administered twice intramuscularly, with the participation of volunteers aged 60 years and older; - to evaluate the reactogenicity of the EpiVacCorona vaccine when administered twice intramuscularly, with the participation of volunteers aged 60 years and older; - to identify any adverse effects to the administration of the vaccine; - to study the humoral and cellular immune responses response following two doses of the EpiVacCorona vaccine, with the participation of volunteers aged 60 and older.

False inclusion (violation of inclusion and nonex-inclusion criteria) or the appearance of exclusion criteria during the study. 3. The decision of the researcher or the Sponsor to exclude the volunteer from the study due to a clinically significant deviation from the protocol/violation of the protocol. 4.
