NCT04036526

Brief Summary

The study should be leaded as a randomized double-blind placebo-controlled comparative research of potency and safety of a GamLPV, a live intranasal Bordetella pertussis vaccine, using two dosing schedules and methods of application in healthy human volunteers. The study contains three periods: screening, inpatient hospitalization and follow-up.

Outcome Measures

Primary Outcomes (2)

  • methods of applications

    selection of methods of applications of GamLPV, a live intranasal Bordetella pertussis vaccine (drop method or nasal actuator is important for vaccination)

    the total Time Frame is 140 days after the vaccination

  • dosing schedules

    selection of dosing schedules of GamLPV, a live intranasal Bordetella pertussis vaccine (repeated administration in 60 days)

    the total Time Frame is 140 days after the vaccination

Secondary Outcomes (4)

  • specific antibody response to B.pertussis

    the total Time Frame is 140 days after the vaccination

  • cell immune responses to B.pertussis

    the total Time Frame is 140 days after the vaccination

  • dynamics of bacteria generation in nasopharynx of human volunteers

    the total Time Frame is 140 days after the vaccination

  • Comparative assessment of immunogenicity

    the total Time Frame is 140 days after the vaccination
