 note = {The immunization program for mumps in Japan was examined by cost benefit analysis. The figures, used in the analysis are actual study results obtained in Japan and foreign countries except some, which were based on an assumption. The figures, which might greatly affect the results were examined by sensitivity analysis. The results of the analysis showed : (1) Mumps vaccination was found not to be beneficial in comparison to its direct cost and direct benefit ; (2) when its indirect cost and indirect benefit were compared, the benefit to cost ratio was 2.72 with 5% of annual discounting rate ; (3) the manifest infection rate was the major determining factor of direct benefit ; and (4) the value of the mother's work was the most influential factor in determining the indirect benefit, and when the value was reduced by half in the present examination with a 5% of annual discounting rate, the B/C ratio was decreased from 2.72 to 1.56.},
