Quote by Edward Jenner

"Vaccination is the medical discovery which has saved more lives than any other single medical intervention in the history of medicine."

"The deviation of man from the state in which he was originally placed by nature seems to have proved to him a prolific source of diseases."

"I hope that some transmissible disease of a milder nature will spread through the population and prepare them for the true thing when it comes."

"Truly the cow-pox secures the constitution from that dreadful scourge the small-pox."

"Never let fear stop you from chasing your dreams."

"Courage is being afraid but doing it anyway."

"Sometimes you gotta do what you gotta do."

"Sometimes you have to be the monster to stop the monsters."
