Vaccination is a method of preventing somebody from catching a disease. The method involves injecting a person with a dead form of an infection. (Technically this is injection of dead pathogens which can’t reproduce, this means that should live pathogens be introduced they will be unable to live, therefore creating immunity to the infection). Vaccination is different to inoculation. Inoculation involves injection of live pathogens in a weakened state. This also results in immunisation. The first use of these techniques in the UK were in relation to Smallpox. Edward jenner learnt of Mary Montague Wortley’s use of inoculation for cowpox, which she had learn in Turey. He used these principles to inoculate against Smallpox by injection of a weakened form of Cowpox.
