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.\n\n * Volunteers are replaced by spares before the introduction of the drug, if the volunteer took the drug, then the replacement is not performed.\n\nAny 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.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '55 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': "IInclusion Criteria\n\n1. written informed consent;\n2. absence of a history, as well as according to a screening examination of pathology from the gastrointestinal tract, liver, kidneys, cardiovascular system, central nervous system, musculoskeletal system, urogenital, immune and endocrine systems, blood, which may affect volunteer safety and evaluation of the results of the study (clinical, instrumental and laboratory studies did not reveal diseases or clinically significant deviations);\n3. males and females within the age range from 18 to 55 years;\n4.
