[Combined experimental use of vaccine against acute human encephalomyelitis and immunomodulators].

Combined use of vaccine and immunomodulators such as ridostin, inosiplex and polyribonate against acute encephalomyelitis of humans (AEMHs) was studied. It was shown that low immunogenic doses of the vaccine did not provide a protective action against the virus of AEMHs while after administration of the vaccine in combination with the immunomodulators there was protection in all the groups of the animals exposed to the low immunogenic doses of the vaccine during the first immunization. It was noted in regard to all the combinations of the immunomodulators and vaccine used in the low immunogenic doses that the level of the increase in the titer of the virus-specific antibodies, the proliferative activity to the specific antigen and mitogens and of interferon induction depended on the immunomodulator type. At the same time, it was found that the marked production of interferon within the first 24 hours observed after the use of the combination of inosiplex, ridostin and the vaccine resulted in increased activity of natural killer cells and lower proliferative activity of cells and production of virus-specific antibodies. This was indicative of the necessity of choosing the immunomodulators, their doses and time of the administration in relation to the immunization.
