Edward Jenner, an English doctor introduced the method of immunization. He observed that people affected by cowpox escaped from the attack of smallpox. He injected the pus taken from a cowpox patient into the body of an 8-year-old boy. The boy was affected by cowpox and recovered. After two months the pus taken from a smallpox patient was injected into the boy. He was not affected by smallpox. The immunization programmes got the name vaccination from the Latin word 'Vacca meaning cow, in memory of the cowpox experiments of Jenner.
