What does vaccina mean?
Vaccina is a rare historical English noun for cowpox, the contagious viral illness of cattle that was central to Edward Jenner's early protection against smallpox. Jenner and his contemporaries described the disease in Latin as variola vaccina, literally “smallpox of the cow,” and the shorter English form appears in older accounts of vaccination. In those contexts, vaccina names the source disease, not a method of inoculation: material taken from cowpox lesions was introduced to produce immunity to the more dangerous smallpox. Today the expression is chiefly encountered in medical history, bibliography, or quotations from early vaccine literature, while “cowpox” is the normal modern term. Vaccina should be understood in its historical sense rather than as a synonym for a particular vaccine or for the modern poxvirus called vaccinia. Its survival offers useful insight into how the vocabulary of inoculation developed around Jenner's work and the Latin description of cowpox.

Where does vaccina come from?
Vaccina entered English through New Latin as the adjective in variola vaccina, literally “cowpox” or “smallpox of the cow,” used to describe the disease. It derives from Latin vacca, meaning “cow,” and vaccinus, meaning “of or from cows,” the same root found in vaccine, vaccinate, and vaccination. The older English noun is distinct from vaccinia, the later scientific name of a related poxvirus.
