[Characteristics of the clinical and immunologic safety of inactivated influenza vaccines in children undergoing multiple immunizations]. / Kharakteristika klinicheskoi i immunologicheskoi bezvrednosti grippoznykh inaktivirovannykh vaktsin dlia detei v usloviiakh mnogokratnoi immunizatsii.

In a strictly controlled epidemiological trial on 12,643 school children aged 11-14 years the reactogenic properties and safety of killed influenza chromatographic vaccine under the conditions of multiple immunization were studied. A single immunization dose of the vaccine (0.2 ml) contained the hemagglutinins of influenza viruses A/Philippines/82 (H3N3) and A/Kiev/59/79 (H1N1), 3.5 micrograms each. The preparation was introduced by means of a jet injector. The vaccine was shown to be clinically and immunologically safe under the conditions of the regular multiple immunization of children over the period of 4 years.

[Use of intraspecific differentiation of Sh. sonnei for the purpose of studying patterns in the epidemic process of dysentery]. / Ispol'zovanie vnutrividovogo differentsirovaniia Sh. sonnei s tsel'iu izucheniia zakonomernostei épidemicheskogo protsessa pri dizenterii.

The use of complex typing of Sh. sonnei by the colicinogenic and enzymatic properties in epidemiological analysis of dysentery caused by Sh. sonnei, apart from establishment of epidemiological connections in the foci, offered a possibility of introducing significant corrections in the determination of the sizes and duration of existence of the epidemic foci, as well as in detection of the sources and factors of transmission of the infection established in epidemiological examination. Typing of Sh. sonnei also aided in ascertaining that, apart from general regularities in the individual territories, the epidemic process in individual groups of the population and in different seasons of the year could also course autonomously.
