Title:

This 1975 photograph depicted a Bangladesh laboratory technician harvesting cowpox virus, otherwise known as vaccina virus, from the underbe

Description:

This 1975 photograph depicted a Bangladesh laboratory technician harvesting cowpox virus, otherwise known as vaccina virus, from the underbelly of a calf that had been inoculated with the virus, resulting in the formation of a maculopapular outbreak from which the would-be vaccine was distilled. The process for creating the smallpox vaccine is a long-standing procedure with a basis firmly tied to the science of epidemiology.'Edward Jenner, an English physician, used folk knowledge to find an alternative to variolation. Recognizing that dairymaids infected with cowpox were immune to small-pox, Jenner deliberately infected James Phipps, an eight year old boy, with cowpox in 1796. He then exposed Phipps to smallpox, which Phipps failed to contract. After repeating the experiment on other children, including his own son, Jenner concluded that vaccination provided immunity to smallpox without the risks of variolation. Jenner's findings were published in 1798.'
