OBJECTIVE: To estimate the impact of influenza vaccine in infants less than two years of age and in elders more than sixty-five years of age, through the analysis of mortality due to influenza and pneumonia in Mexico, between 1990 and 2005. To determine the seasonal pattern of mortality, the tendency of mortality by volume of deaths per seasonal period, and the speed rate of mortality. MATERIAL AND METHODS: Data were taken from the Epidemiological and Statistical Mortality System (SEED-SSA per its abbreviation in Spanish). RESULTS AND CONCLUSIONS: The analysis showed there is a tendency of deaths decrease at a rate of 509 deaths less per year in the infants group and 29 deaths less in the elders group. Also, the ascending tendency of mortality was interrupted by vaccination. The vaccination intervention has a positive economic effect and also helps improve the quality of life.Therefore, its implementation is expected to lower hospital admissions and deaths.
