Vaccination for Poliomyelitis.
—There have been no reports of unfavorable results from the use of Sabin vaccine type I against poliomyelitis in Japan. With knotty technical problems out of the way, the quality production of the Sabin vaccine is now geared to meet the nation's demands. Except where Salk vaccine is expressly requested, the Sabin live vaccines will be used uniformly from now on. Accordingly, at the forthcoming session of the lower house of the Japanese Parliament, the existing laws relating to polio and vaccination will be so rewritten as to make the use of the Sabin vaccine compulsory. Effective in 1964, according to the authorities, the diphtheria and whooping cough vaccines as well as Sabin vaccines will be distributed free of charge throughout the country.
