| Abstract: | Combined vaccine "Bubo-Kok" is characterized by safety and high immunological activity. The number of postvaccinal reactions in children aged 1 and 2 years, immunized with vaccine "Bubo-Kok", was not statistically different from those in groups of children immunized with adsorbed DPT vaccine, as well with such vaccine in combination with vaccine against hepatitis B. After the completion of the primary course of immunization 100% of children had protective antibody titers against diphtheria, tetanus and hepatitis B. Antibody titers against pertussis, equal to or exceeding protective titers, were found in more than 70% of immunized children. The immunogenic potency of vaccine "Bubo-Kok" with respect to all its components was not inferior to that of adsorbed DPT vaccine and vaccine against hepatitis B, when introduced simultaneously in different areas of the body. Vaccine "Bubo-Kok" successfully passed state trials and was recommended for registration. |
