Cowpox
Cowpox, contagious viral disease of cows characterized by pustular eruptions, especially on the udders and teats. Cowpox can be transmitted to humans by direct contact. Persons infected with cowpox become immune to smallpox, a similar but more serious disease. This immunity was discovered by the British physician Edward Jenner, who used cowpox virus to inoculate patients against smallpox.
