Public vaccination began after English physician Edward Jenner learned that milkmaids were protected from smallpox after exposure to cowpox, a related virus in cows.
In 1798, the English physician Edward Jenner had shown that an injection of cowpox — variolae vaccinae — protected people from the horrors of smallpox.
Another function of the board of health is the preparation and distribution of vaccine (material containing the virus of cowpox).
Whether cowpox is a modified form of smallpox or a distinct disease is unknown.
After he had differentiated genuine cowpox, however, there was no difficulty in tracing its apparent protective power.
The boy went through an attack of cowpox in a regularly satisfactory manner.
Jenner demonstrated conclusively that the cowpox protects the human constitution from the infection of smallpox.
