SAFETY AND IMMUNOGENICITY OF A NATIONAL COMBINED VACCINE AGAINST PERTUSSIS, DIPHTHERIA, TETANUS, HEPATITIS B AND Hib-INFECTION, CONTAINING ACELLULAR PERTUSSIS COMPONENT, DURING IMMUNIZATION OF ADULTS

Aim. Study safety, reactogenicity and immunologic effectiveness of a national combined vaccine against diphtheria, pertussis (acellular component), tetanus, hepatitis B and Hib-infection during immunization of volunteers aged 18 - 60 years. Materials and methods. The study was carried out in accordance with ethical standards and requirements, regulated by Helsinki declaration and Good clinical practice (ICHGCP). In a simple non-randomized clinical trial 20 adult volunteers took part, the mean age of those was 46.9 years. Results. Registered post-vaccination reactions (both local and systemic) were mild and of moderate degree of severity, stopped independently after 2 - 3 days without administration of drug treatment. Postvaccinal complications were not noted. Parameters of general and biochemical analysis of blood, urine, IgE content in dynamics of immunization were within normal limits. A single administration of aAPDT-HepB+Hib to individuals aged 18 - 60 years resulted in development of antibodies against all the components of the preparation. Seroconversion factor fluctuated from 6.9 to 53.5. Conclusion. The results obtained allow to recommend the vaccine for evaluation of its safety, reactogenicity, immunologic and prophylaxis effectiveness in randomized clinical observation trials in children

RESULTS OF A MULTICENTER CLINICAL STUDY OF A NEW COMBINATION VACCINE DTaP-HepB+Hib PRODUCTION OF THE CPA «MICROGEN» FOR IMMUNIZATION OF CHILDREN 6 MONTHS

Aim. The aim of the study is evaluate of reactogenicity, safety and immunogenicity of the native combined vaccine DTaP-HepB+Hib. Materials and methods. Assessment of reactogenicity, safety and immunogenicity of the drug is investigated in a multicenter, comparative, randomized, simple-blind clinical trial of immunization of children 6 months (the comparator vaccine DTaP-HepB combined vaccine, Hiberix®). Results. The native combined vaccine DTaP-HepB+Hib is characterized by good tolerability, high safety profile and a pronounced immunogenicity. In terms of seroprotection, seroconversion and geometric mean titers of antibodies comparable to that used in Russia of vaccines DTP-HBV and Hiberix®. Conclusion. Vaccine DTaP-HepB+Hib can be recommended for registration in the territory of the Russian Federation for the prevention of pertussis, diphtheria, tetanus, hepatitis B and Hib-infection
