A revolutionary invention in modern medicine has changed the world in the past fifty years. In the 20th century, diseases such as polio, diphtheria, and rubella were commonplace and claimed millions of lives. Now they are something of the past- these illnesses are considered ‘eradicated diseases’. This massive increase in population immunization is due to the invention of vaccines and artificially acquired immunity. Vaccinations are critically important in preventing and maintaining individual and public health concerns. When people have infections or illnesses for the first time their immune systems have to fight them off. At first the invader is defined by foreign and unknown by an individual’s immune system, but it progressively gets better and better until the infection is eradicated. By then, your immune system has ‘memorized’ how to fight them off, resulting in what is known as naturally acquired immunity.

This is where vaccines come into play. Vaccines harmlessly imitate infections to stimulate an individual’s immune system. The artificial ‘infection’ is taken down by the body very quickly with virtually no side effects or risk of death.
