    Abstract:
    Two serological tests--single radial hemolysis (RSH) and hemagglutination inhibition (HI) were used to evaluate the different techniques (intranasal, intradermal and combined methods) of application of inactivated influenza vaccines. When seroconversion to hemagglutinin (HA) was determined sensitivity of SRH proved to be higher as compared with HI by 6.7-41.4%. This test has also shown that the frequency of the seroconversion to HA was 2.1-5.6 times higher than that to neuraminidase (NA). It is important to standardize both HA and NA components in the influenza vaccine. It is interesting to study the local and cell immunity after intranasal inoculation of influenza vaccine because of the low postvaccinal level of serum antibodies and in connection with some publications concerning the protective role of this immunization method.
