Aim: To temporally describe the hospital morbidity in the elderly population due to influenza related causes and its complications and to estimate the effects of the vaccine over its coefficients in Brazilian Southern State of Santa Catarina. Methods: An ecological study combining temporal series from 1995 to 2009 was carried out. Secondary data from the Brazilian Sistema de Informações Hospitalares was used. The study's population was composed by records of 60 year old individuals and older, who was living in the nine macroregions of health of the state. To observe the number of hospital admissions, influenza related causes and its complications according to the International Classification of Diseases were used. It was estimated the coefficient of hospital admissions according to gender and age for the state, the death rate regardless the sex and age, the seasonal effect. The effect of seasonality and vaccine were measured using multiple linear regressions. Results: Males and the group of age of 80 and over showed higher rates of hospital admissions. Variations were observed, with a decrease of 15.8% in the first quarters of the years of the study, and an increase of 14.9% in the thirds quarters highlighting the effects of seasonality. It was also observed a decrease of 18.9% from 1999 on. Conclusion: It was observed important effects on the hospitalization admissions rates in Santa Catarina associated to seasonality and to the introduction of the influenza vaccination campaigns in the studied period.
