Inoculation refers to the induction of an infective organism to produce immunity against various infectious diseases (Definition). In Western medicine, inoculation was the process of preventing smallpox by purposefully infecting a person with the disease in a controlled manner to prevent further infection (Meacham).

However, in 1796 English physician Edward Jenner attempted a newer method of inoculation: Jenner transported cowpox directly from an infected milkmaid into the arm of a child and, after two months, he exposed the child to smallpox and the child remained uninfected (Meacham). Jenner’s new procedure became known as vaccination and has been used for over 200 years to treat numerous infectious diseases (Meacham).
Vaccination and inoculation are often used interchangeably, however, they distinctively differ in their methods of administration. Inoculation refers to purposefully infecting a person with live pathogens, while vaccination is the process of treating a person with weakened or dead pathogens (Meacham). Both are immunization processes and are used in order to induce immunity. Since the pathogens in vaccines are not live, they help to develop immunity by imitating the infection without causing illness (Understanding). When the immune system senses the pathogen, it begins to produce antibodies which fight the artificial infection (Understanding). Once the pathogen is gone,…
