[Comparative analysis of tests on in vitro and in vivo quantitative assessment of the immunogenicity of tick-borne encephalitis vaccine].

Many-year routine use of EIA as an in vitro test demonstrated it as a highly reproducible and technological test for assessing the efficacy of vaccine against tick-borne encephalitis and its semiproducts at the intermediate stages of vaccine production. The reproducibility of mouse protection test is notably inferior to that of EIA.
