The monitoring of the vaccime EnceVir® efficacy in the expressx scheme immunization of adults

In this research blood serum was tested for specific antibodies so as to investigate the immune system tension in distant periods after the immunization with the tick-borne encephalitis vaccine EnceVir®. It was shown that twelve months after the completion of the initial course of vaccination all the vaccinated adults had specific IgG, with titer rate varying from 1:800 to 1:3200. The retrospective analysis of the vaccines side effects revealed several batches with an elevated number of temperature reactions. Nevertheless, over 80% of the used vaccine batches did not contradict with the EnceVir® instruction manual in terms of the number of side effects.
