Vaccination against pneumococcal infection in adults from risk groups

Abstract

In Russia starting from 2014, adults from risk groups are vaccinated against pneumococcal infection in accordance with the vaccination calendar based on epidemic indications. However, data collected by the Epidemiological Surveillance for Vaccine Prevention do not allow to judge about the protection of adult population against pneumococcal disease, as there is no information on the coverage of risk groups. The objective : to analyze the coverage of adult population from risk groups with vaccination against pneumococcal infection. Subjects and methods. The number and groups of adults vaccinated against pneumococcal infection were provided by the executive authorities in charge of health care in the Russian Federation. Data for 4 years were collected (201 5-2 018). The information was received from 79 regions of the Russian Federation. Descriptive statistics methods were used to analyze the coverage in age and occupational risk groups and people with chronic diseases. Results . The main groups of adults vaccinated against pneumococcal infection were the following: patients with chronic diseases (55%, including 27.5% of patients with chronic lung disease), conscripts (30%), various occupational risk groups (11%). The remaining risk groups accounted for less than 5% of vaccinations. The maximum coverage was achieved among adults with chronic lung disease (15.1%). Among patients with chronic no n-p ulmonary diseases, coverage was the following: patients with liver diseases – 4%, cardiovascular diseases – 3.8%, endocrine system – 2.8%, immunodeficiencies – 1%. In other groups of chronic patients, coverage was even lower. Among adults with occupational risk factors and staying in special conditions, the maximum vaccination coverage was achieved among conscripts (67.4%). Vaccination in other categories of occupational risk was performed in a small number of people; among health workers, it was 4.9%, among employees of educational organizations of open type (schools, kindergartens, etc.) it made 3.1%.
