Edward Jenner

I look forward with confidence to the time when the smallpox shall be known only by history.

The vaccine virus is a gift of Providence, which we are bound to use for the good of our fellow creatures.

In medicine, as in every other science, we must be guided by observation and experiment, not by theory alone.

The fear of smallpox has been the torment of human life; vaccination has removed that fear.

I have never sought fame or fortune; my only object has been to relieve the sufferings of my fellow men.

The practice of vaccination is founded on the laws of nature, and is therefore permanent and invariable in its effects.

The vaccine discovery is the most important event in the history of medicine since the time of Hippocrates.

Let us propagate vaccination with zeal, but with prudence; let us be guided by facts, not by opinions.
