[An evaluation of the efficacy of measures for preventing enterobiasis in Leningrad Province].

Assessment of the enterobiasis preventive measures in the children's institutions of Leningrad Province demonstrated that wide treatment-and-prophylactic measures didn't reduce enterobiasis. Low efficiency (0.5% of positive results) was found in the sanitary helminthological examination of utensils, which had been performed at the pediatric institutions.

[Evaluation of the safety, reactogenicity and antigenic activity of inactivated chromatographic influenza vaccine in school children].

To evaluate the safety, reactogenicity and immunogenicity of inactivated chromatographic influenza vaccine A(H3N2) produced by the Pasteur Research Institute of Epidemiology and Microbiology in Leningrad, children aged 7-15 years received the vaccine intradermally in doses of 114-228 IU, and 152 children received placebo. In this study inactivated influenza vaccine introduced parenterally to children aged 11-15 years in a dose of 228 IU proved to be nonreactogenic. The reactogenicity index of the preparation injected in a dose of 114 IU to children aged 7-10 years was 0.
