Word origin

The term 'vaccinia' comes from the Latin word 'vacca,' meaning 'cow,' due to its association with the cowpox virus. The use of vaccinia as a vaccine originated in the late 18th century when Edward Jenner observed that milkmaids who contracted cowpox did not get smallpox. Based on his observations, he used material from cowpox lesions to successfully immunize individuals against smallpox, effectively laying the groundwork for the use of vaccinia in vaccination. The practice of vaccination evolved significantly over time, with vaccinia being an integral component in the eradication of smallpox, the first disease to be eliminated through human efforts.
