On the most effective timing of immunization with native and purified adsorbed diphtheria toxoid in the experiment

At present, the success of immunization against diphtheria is so significant that the health authorities have embarked on a course to eliminate the disease. In the fight against diphtheria, not only the coverage of vaccinations among the broad masses of children, but also the correct organization of vaccination, play an important role. With active immunization with toxoid, the interval between vaccination and the first revaccination is very important in the development of a sufficiently stable and long-term anti-diphtheria immunity. Meanwhile, the question of the optimal interval between the second vaccination and the next revaccination cannot be considered finally resolved.
