About

Observational program, double-blind, placebo-controlled to study the preventive efficacy of the BiVac polio (Oral polio vaccine, divalent, live attenuated of types 1 and 3 vaccine against the incidence of acute respiratory infections, including COVID-19

Full description

To carry out a comparative assessment of the indices of humoral, cellular immunity and cytokine profile in patients with acute respiratory infections.

Current Program Population: 1500 healthy male and female volunteers, aged of between 18 and 65 will be included in the program.

All included volunteers will be divided into groups:

Group 1 - 750 volunteers who will be vaccinated with BiVac polio vaccine; post-vaccination observation period of 12 months.

Group 2 - 750 volunteers, placebo will be administered, post-vaccination observation period of 12 months.

The probability of getting into one of the two groups for each volunteer will be 50%.

Enrollment: 1,500 patients

Sex: All

Ages: 18 to 65 years old

Volunteers: Accepts Healthy Volunteers

• Pregnancy.
• Hypersensitivity to any component of the vaccine.
• Strong reaction (temperature above 40°C) or a complication on the previous administration of the drug.
• Acute infectious or non-infectious diseases. Vaccinations are carried out 2-4 weeks after recovery or remission. In case of mild acute respiratory viral infections, acute intestinal diseases, vaccinations are carried out after the temperature normalizes.
• The presence in the family or immediate environment (and provided that it is impossible to separate) of unvaccinated against polio (for example, newborns or children who have contraindications to polio vaccinations).
• The presence of persons with immunodeficiency in the family or immediate environment (and provided that it is impossible to separate).

Exclusion criteria

• A volunteer can be excluded from the study under the following conditions:

  • Refusal of a volunteer to participate in the program.

  • The need for procedures and / or drug treatment that are not permitted by the protocol of this study.

  • The volunteer was included in violation of the inclusion/non-inclusion criteria of the Protocol.

  • The appearance of non-inclusion criteria during the study.

  • Non-compliance with the research procedures by the volunteer.

    • Any condition of the volunteer that requires, in the reasonable opinion of the research doctor, the withdrawal of the volunteer from the study.

  • The volunteer is out of observation. • For administrative reasons
