Before the introduction of planned vaccination against diphtheria in Tatarstan, the number of diphtheria cases per 100 thousand people was 25.3 in 1920-1929 - 25.3, 1930-1939 - 66.5, 1940-1949 - 75.4, 1950-1959 - 67,2. Planned vaccination, which began in 1955-1956, contributed to a decrease in the number of cases. Over the following decades, the average incidence rate per 100,000 population steadily decreased and was in 1960-1969 - 5.2, 1970-1979 - 0,07. However, in 1982-1985 there was a slight increase in the number of diphtheria cases, so the average morbidity rate for 1980-1989 slightly increased (0.09 per 100 thousand population).
