This course will investigate how some infectious diseases are successfully eliminated from various parts of the globe. We will first study eradication of smallpox in 1980, two centuries after Edward Jenner successfully inoculated a child. We will next look at the efforts spanning over 100 years to eliminate Japanese schistomiasis from Japan where several graduates from Tokyo University played key roles. We then investigate measles, mumps and rubella (MMR) vaccine scandal in the UK. We will also evaluate the different policies against rabies among countries free of the disease. In final weeks, students will choose an infectious disease of their interest and propose counter measures to the class.
