Etymology:
The word "vaccinate" is derived from the Latin word "vacca," which means "cow."
Origin:
The term was first used in the late 18th century by Edward Jenner, an English physician who developed the first vaccine against smallpox. Jenner noticed that milkmaids who had been exposed to cowpox, a mild disease that caused sores on their hands, were immune to smallpox. He hypothesized that the cowpox virus could be used to protect people against smallpox, and he conducted a series of experiments that proved his theory.
Meaning:
To vaccinate means to introduce a vaccine into the body to provide immunity against a specific disease. Vaccines are typically given by injection, but they can also be given orally or through the nose.
Process:
Vaccination involves exposing the body to a weakened or inactivated form of a pathogen (virus or bacteria) to trigger the immune system to produce antibodies and other immune cells that can recognize and fight off the disease if it is encountered in the future.
