The Spatio-Temporality of Virus and Vaccine
The tale of the importation and spread of the vaccine has already received much attention [Jannetta]. But there is another, equally important aspect to the story of the vaccine that has only begun to be told: its perpetuation over time. Because of the spatial and temporal limitations of the biological properties of the cowpox vaccine, physicians faced major hurdles in trying to keep it in circulation. As Yanagisawa Fumiko has noted, the vaccination rate in Fukui prefecture (which roughly overlaps with Echizen province) only crossed the eighty-percent mark in the second half of the 1880s [Yanagisawa, 2018, p. 59]. This figure suggests that even under the centralized structure of the Meiji state with its emphasis on public health, the goal of full coverage was not easy to attain.
