Edward Jenner

I consider vaccination as the most important discovery ever made in medicine.

The benefits already derived from vaccination are incalculable; and the prospect of its future utility is unbounded.

Nature, in the production of disease, is uniform and consistent; so much so, that for every disease she has produced, she has also provided a remedy.

The vaccine virus is a substance which, when inserted into the human body, produces a mild disease, which forever after protects that body from the smallpox.

I have placed my discovery in the hands of the public; let them do with it as they please.

The practice of vaccination will, I trust, be the means of eradicating smallpox from the face of the earth.

The cow-pox is a disease which, when communicated to the human subject, produces a mild illness, but which forever after secures the constitution from the smallpox.

I am satisfied that the vaccine disease is a complete safeguard against the smallpox.

The vaccine discovery is not mine; it is the property of mankind.

It is to the benevolence of the Deity that we owe this great discovery, which will, I trust, be the means of saving millions of lives.

The smallpox has been the most terrible minister of death that ever afflicted humanity; vaccination will be its conqueror.

The progress of vaccination is slow but sure; prejudice and ignorance are its only enemies.

I have never known a single instance of a person who had undergone the vaccine disease, who was afterwards susceptible of the smallpox.

The vaccine virus is a specific for the smallpox, as certain as that bark is a specific for the ague.

Let us not be discouraged by the opposition of the ignorant; truth will ultimately prevail.

The practice of inoculation for the smallpox is now rendered unnecessary by the more safe and certain practice of vaccination.

I have devoted my life to the service of humanity; and if I have been instrumental in saving lives, I am content.

The vaccine disease is so mild, that it scarcely deserves the name of a disease.

The discovery of vaccination was not the work of a moment; it was the result of many years of patient observation and experiment.

The benefits of vaccination are not confined to any country or climate; they are universal.
