Smallpox vaccination results (OpenIntro)
A sample of 6,224 individuals from the year 1721 who were exposed to smallpox in Boston. Some of them had received a vaccine (inoculated) while others had not. Doctors at the time believed that inoculation, which involves exposing a person to the disease in a controlled form, could reduce the likelihood of death.
