Jenner inoculated Phipps in both arms, making Phipps develop a fever and some uneasiness, but no full-blown infection. Later, Jenner injected Phipps with variolous material, and no disease followed. The boy was later challenged with variolous material once again, and just like the first time, showed no sign of infection. Jenner successfully repeated the test on 23 other subjects, including his 11-month-old son. Now, he’s referred to as “the father of immunology”, and his work is said to have “saved more lives than the work of any other human.”Few public health measures can compare to vaccines. Vaccinations have reduced disease, disability, and death from a variety of infectious diseases. In addition to saving lives, vaccination has resulted in economic benefits to societies, amounting to almost $69 billion in the United States alone. A recent economic analysis of 10 vaccines for 94 countries estimated that a $34 billion immunization investment resulted in savings of $586 billion in reducing costs of illness and $1.53 trillion when broader economic benefits…
