An infectious viral disease of cattle which can be transmitted to humans. It was used as a constituent of the first vaccines for smallpox.
Mild disease characterized by a pustular rash and caused by vaccinia virus transmitted to humans from infected cattle. Cowpox infection confers immunity to smallpox, which is caused by a similar virus. Also called vaccinia.
A virus infection of cows udders transmitted to man by direct contact, causing very mild symptoms similar to smallpox. An attack confers immunity to smallpox.
Cowpox is a disease affecting the udders of cows, on which it produces vesicles. It is communicable to humans, and there has for centuries been a tradition that persons who have caught this disease from cows do not suffer afterwards from smallpox. This formed the basis for Jenner’s experiments on vaccination.
An infection caused by the vaccinia virus, primarily known to afflict bovine species, historically served as a means to bestow immunity against smallpox. This particular virus, employed in the past for its protective effects, elicits a robust immune response that safeguarded individuals against the perils of smallpox.
