Vaccines Are One Of The Biggest Health Achievements In History

Before Jenner’s discovery, smallpox outbreaks would eliminate entire villages. Before the polio vaccine, children who contracted the diseases and did not die from it were often paralyzed for the rest of their lives. Cholera would contaminate city waterways and thereby cause outbreaks that spanned entire cities and decimated populations.

Vaccines changed all of this. Smallpox cases are now things that you read about in history books or watch documentary movies on. Many today do not even know what cholera is, or whooping cough, or diphtheria. Because generations of children have been vaccinated against these diseases, they no longer pose a threat to public health.
