Why is vaccination important?
To become permanently immune to many illnesses, you must either catch it, or be vaccinated against it. The first child ever to be vaccinated was James Phipps in 1796. The English doctor Edward Jenner injected him with cowpox, which made him immune to smallpox, a far more deadly disease. These days, more than half the children in the world are given vaccines against whooping cough, diphtheria, tetanus, polio, measles and tuberculosis.
