[Evaluating efficiency of combined vaccination against influenza and pneumococcal infection in workers of "Gazprom transgaz Yekaterinburg" company].

Influenza-like diseases are among the causes of disability. Risk of these diseases is increased with other occupational hazards. The study covered efficiency of combined vaccination against influenza (annually, over 2 years, with inactivated split-vaccine Vaxigrip) and pneumococcal infection (single, with 23-valent pneumococcal polysaccharide vaccine Pneumo 23) in 318 workers of Neviansk branch of "Gazprom transgaz Yekaterinburg" company. Among them, 49 workers (welders and joiners) were exposed to occupational hazards. Findings are that general frequency of such diseases decreased by 17% over the first year after the vaccination and by 27% over the second year, and in welders and joiners group--by 33% and 44% respectively. The authors proved economic efficiency of combined vaccination with Vaxigrip and Pneumo 23.
