Abstract
The dynamics of the incidence of chickenpox and herpes zoster in the population of the Irkutsk region and the city of Irkutsk against the background of ongoing selective vaccination was studied. A descriptive epidemiological study was conducted according to state statistical reporting based on materials from the Irkutsk region and the city of Irkutsk for 2013-2022. The calculation of predictive values was made using regression equations, the statistical significance of differences in intensive indicators was assessed by 95% CI. Against the background of a decrease in the incidence of chickenpox, in 2021-2022. There was an increase in the indicator among different age groups of the population, the most significant among children under 6 years of age. According to the forecast, in 2023 the incidence rate will not change significantly. Selective vaccination tactics do not significantly affect the incidence of chickenpox (p = -0.217; -0.7; p>0.05). The incidence of shingles in the region exceeds the national level. Taking into account the continuing epidemiological trouble for chicken pox in the region and the data of forecast calculations, it is necessary to adjust the existing vaccination programs, including gradually expanding the contingents to be vaccinated.
