    The analysis of the use of the method for the evaluation of specific (immunogenic) activity of vaccines for preventing tick-borne encephalitis (TBE vaccines) against protective dilution (PD50) and the minimum immunizing dose (MID50) has been performed. The method was standardized and submitted to the regulatory documents for TBE vaccines authorized in the Russian Federation. When analyzing the results of the study of specific (immunogenic) activity of TBE vaccines (107 TBE vaccine batches by different manufacturers have been studied) it was confirmed that the choice of real lethal dose (RLD50) indicator of TBE virus (test strain Β«AbsettarovΒ») in the range of 100-3000 LD50, the reasonability of using BALB /c cell-line mice, the effectiveness of the national method of determining immunogenicity in terms of MlD50 for TBE vaccines authorized in the Russian Federation. The reasonability of using immunogenicity reference standard for TBE-OSO 42-28-48 to assess the reproducibility of the experiments, and the homogeneity of laboratory animals in terms of quality. Methods for determining TBE vaccine immunogenicity (Β«specific activity (immunogenicity)Β» in terms of PD50 and MID50 is applicable both for Russian commercial TBE vaccines and for FSME-Immun vaccine, manufactured by Β«Baxter Vaccine AGΒ», Austria.ΠŸΡ€ΠΎΠ²Π΅Π΄Π΅Π½ Π°Π½Π°Π»ΠΈΠ· примСнСния ΠΌΠ΅Ρ‚ΠΎΠ΄Π° ΠΎΡ†Π΅Π½ΠΊΠΈ спСцифичСской (ΠΈΠΌΠΌΡƒΠ½ΠΎΠ³Π΅Π½Π½ΠΎΠΉ) активности соврСмСнных Π²Π°ΠΊΡ†ΠΈΠ½ ΠΊΠ»Π΅Ρ‰Π΅Π²ΠΎΠ³ΠΎ энцСфалита (Π²Π°ΠΊΡ†ΠΈΠ½Ρ‹ КЭ) ΠΏΠΎ ΠΏΡ€ΠΎΡ‚Π΅ΠΊΡ‚ΠΈΠ²Π½ΠΎΠΌΡƒ Ρ€Π°Π·Π²Π΅Π΄Π΅Π½ΠΈΡŽ (ПР50) ΠΈ минимальной ΠΈΠΌΠΌΡƒΠ½ΠΈΠ·ΠΈΡ€ΡƒΡŽΡ‰Π΅ΠΉ Π΄ΠΎΠ·Π΅ (ΠœΠ˜Π”50).
