Abstract :

The coverage rate of mumps vacccine is 30-40% for one-dose in Japan. The reasons of low coverage is that the govenment does not include mumps vaccine into National Immunization Program (NIP). Major governmental concerns for inclusion are social will, cost-effectiveness, aseptic meningitis as one of adverse events. Aseptic meningitis after vaccination made the goverment stop routine mumps vaccinaation since 1993; however, it has been shown that incoodence of aseptic meningitis was as 1/5,000-7,000 (Hoshino and Torii strains) at 1 year old which was lower than expected. In this presentation, the studies about cost-effectiveness analyses and social will will be indroduced. First, static model simulation was performed and resulted that cost-benefit ratios were 3.69 and 6.84 in independent inoculation and simultaneous inoculation, respectively, from a social perspective. In addition, dynamic transmission model was used to consider herd immunity with the result that two-dose vacination program was always dominating over one-dose or current program in all scenarios. In terms of social will, a questionnaire survey was performed to Japanese parents if they wish that mumps vaccines are included into NIP after giving current information. The result was that 95.0% of parents want routine mumps vacccination In countries with high coverages of two-dose vaccines, mumps outbreaks still exist. Once Japanese goverment approve routine vaccination, we can compare the effiicacies between Jeryl-Lynn strain and Japanese strain and further investigate the best vaccine strain and schedule.
