REVACCINATION AGAINST TULAREMIA (O REVAKTSINATSII PROTIV TULIAREMII)

The necessity of revaccination among a large percentage of population must be determined by the condition of immunity of the vaccinated people and to the epidemiological evidence for specific prophylactic. A firm retention of immunity caused by vaccination against tularemia during 4 to 5 years basically proves that the revaccination should not be carried out prior to that period. In case epidemiological evidence requires vaccination of the population, where mass vaccination had been previously carried out prior to that period. In case epidemiological evidence requires vaccination of the population, where mass vaccination had been previously carried out, an allergy test of immunity must be made, and should negative reaction of more than 25% of the vaccinated appear, revaccination should be carried out. When the revaccination is carried out 3 years after the primary local skin vaccination the vaccination process with 83.5% of the revaccinated people occurs as an allergic reaction. With people who were previously vaccinated and lost the allergy reaction, the revaccination process in its progress and duration entirely corresponds in most cases with the progress of the primary vaccination process.
