EFFECT OF ANTI-FLU VACCINATION ON MORBIDITY ACCOMPANIED BY TEMPORAL INCAPABILITY TO WORK AMONG EMPLOYEES OF SOME MINSK ENTERPRISES
Objective. Evaluation of the anti-flu vaccination effect on values of the morbidity accompanied by temporal incapability to work among employees of some Minsk enterprises was the objective of the study. Materials and methods. The data concerning the anti-flu vaccination outcomes among employees of 29 Minsk building enterprises in 2011, the information about the morbidity rate among the employees temporally incapable to work in quarter I of 2012 as well as the data about morbidity accompanied by temporal incapability to work among employees of ten Minsk industrial enterprises for the period quarter I of 2008 to quarter I of 2012 served the material for studying. The qualitative variables distribution normality was determined applying Kolmogorov — Smirnov's test. The statistical reliability of qualitative variables differences between the groups was determined with the single factor analysis of variance. The data suitability for the analysis of variance was assessed in calculating the Levene's test of the homogeneity variance. Correlation between two variables was assessed using Pearson's correlation coefficient. The economic efficacy of the anti-flu vaccination of working population and of expenses prevented by vaccination was calculated by the standard method. Results. The values of morbidity accompanied by temporal incapability to work among the employees of building enterprises where more than 35% of workers had been vaccinated against flu were reliably lower than among the employees of building enterprises where less than 35% of workers had been vaccinated against flu. A strong reverse correlation between the vaccination rate and the rate of the morbidity accompanied by temporal incapability to work was revealed. A trend to the morbidity accompanied by temporal incapability to work reducing was observed on the background of the anti-flu vaccination extension at the enterprises participated in the 2008—2012 years monitoring. Conclusion. Vaccination of 35%—40% of employees is expedient as concerns the expenses and the benefit achieved ratio allowing effect positively the level of the morbidity accompanied by temporal incapability to work.
