Эпидемиологическая и социально-экономическая оценка эффективности программы однократной вакцинации против ветряной оспы детей 6 лет на примере Алтайского края

Abstract

Introduction. Chickenpox is one of the most common and highly contagious infections. Since the domestic vaccine has not been developed at the moment, and the purchase of an imported vaccine for routine vaccination is an expensive investment of the state, there is a need to assess the epidemiological and socio-economic effectiveness of vaccination. Purpose: to evaluate the epidemiological and socio-economic effectiveness of a single vaccination program against chickenpox in children aged 6 years on the example of the Altai Territory. Materials and methods. The materials were the reporting forms No. 2 of the Federal State Statistical Observation "Information on infectious and parasitic diseases" in the city of Barnaul for 2001-2019. The economic assessment was carried out on the basis of MU 3.3.1878-04 of 04.03.2004 "Economic efficiency of vaccination". The method of simulation modeling was used to assess the epidemiological effectiveness. Results. The cost of treating chickenpox is almost twice the cost of a vaccination program. The self-sufficiency of vaccination of a cohort of children 6 years of age against chickenpox, carried out in 2021, will be achieved during 2031, and in the future, the damage prevented will constantly increase. The economic benefit will amount to about 7.52 million rubles, and the prevented damage will exceed the costs by 1.2 times. The epidemiological effectiveness of vaccination is observed after five years of the program implementation, the incidence decreases 2-2.5 times. Conclusions. Taking into account the data of literary sources, it is advisable to vaccinate children according to the program of double cohort vaccination with the introduction of the first dose of the vaccine at 12 months and the second dose at 6 years. However, in regions such as the Altai Territory, where previously there was no vaccination of chickenpox, at the initial stage of implementation it is necessary to vaccinate children over 6 years of age in order to prevent the "maturation" of the infection.
