Vaccine Definition

A vaccine is defined as any substance which is used to stimulate the production of antibodies, in-turn providing immunity against one or few diseases

A vaccine is defined as a biological preparation formulated to provide acquired immunity for a particular disease. Usually, vaccines contain a weakened or killed form of the disease-causing agent, its surface proteins or its toxins. When this preparation is introduced into the human body, the immune system is able to recognize the threat and destroy it. Moreover, the body will “remember” the threat and can initiate an appropriate response if encountered in the future.

The process of administering the vaccine is called vaccination. It is responsible for the eradication of many diseases – especially infectious diseases such as smallpox and chickenpox. The term “vaccine” is derived from the Latin word “vaccinus”, from “vacca”, which means “from cows”. Edward Jenner coined the term for the technique where, he injected individuals with a mild form of cowpox, thereby rendering them immune to small pox
