[Quantitative indices of the immune status of persons inoculated with different vaccines against tick-borne encephalitis]

Inactivated concentrated and unconcentrated vaccines against tick-borne encephalitis given to 80 normal subjects produced no suppressing effect on the quantitative values of the immune status. Immunogenesis was characterized by stimulation of both T- and B-links of the immune system of the vaccines. With the unconcentrated vaccine a greater response was demonstrated after 3 injections; the concentrated vaccine induced an intensive immune response after 2 injections.
