I am going to come straight with you on this one. When it comes to leading lights in vaccinations, most of my historical knowledge ends with perhaps the man we could call the Godfather of Vaccinations, Edward Jenner. Jenner, of course, invented the vaccination for smallpox and started a revolution in medical science. As with an appreciation of the role bacteria play, vaccinating distinguishes itself to the majority of medical treatments in its proactive nature. It puts into the practice the principle that prevention is always better than the cure. By administering a controlled dosage of a disease - in Jenner's case cowpox - an individual's immune system can be activated and thus prevented from contracting a debilitating or potentially fatal disease - in Jenner's case small pox. A continued campaign of vaccinations can completely drive out a disease in a country, as it has done with many deadly diseases we all feared on a relatively short time ago.
