[Cost-effectiveness analysis of antigrippal vaccination in a rural population (La Victoria, Cordoba)]. / Análisis de rentabilidad de la vacunación antigripal en una población rural (La Victoria, Córdoba).

After 4 successive campaigns of influenza vaccination (1984-1988) in La Victoria (Córdoba), a village with a population of 1750, the economic cost-effectiveness was estimated on the basis of the effectiveness attributable to the vaccine and that actually found. The mean cost of an influenza case amounted to 69,295 pesetas. The vaccine coverage increased during the study period from 20% to 30% in the general population and from 63% to 78% in the risk population. The effectiveness of vaccination, variable among years, was as a rule lower than expected. Cost-effectiveness was not related with the magnitude of the coverage, but increased proportionally with the morbidity rate.
