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."

"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."

"Nature has been a beneficent providence to us in the discovery of vaccination."

"You can't expect to be happy if you're surrounded by mess."

"Health and happiness - these are true wealth"

"How can you live like this? It's like a pigsty!"

"You're going to get sick living like this."
