We have evaluated the fulfillment of the aims of an integrated influenza vaccination program for a basic urban health area. We have focused the analysis on the vaccine coverage for age and sex groups, groups of risk modifiers and risk gradient. We have evaluated the most adequate method of call. Overall coverage was 64.6%. This rate was higher in risk groups such as diabetes, heart disease and chronic airflow limitation. Rates of 74.9%, 81.8% and 94.11% were achieved in groups with two, three and four risk modifiers. The direct call was considered the most effective method of catchment. The major conclusion was that the attempted coverage rates were not achieved. We suggest that the "non-vaccinated" individual profile should be investigated and the motivation level of the health professionals should be improved to increase the yield of the influenza vaccination programs.
