I cannot see how this fact can be explained on any other principle than that of the ‘protective’ influence of the vaccination on the children which had received it; whilst, on the other hand, the gradual decline of that protection (now admitted by all vaccinationists) left a large proportion of the vaccinated open to be attacked in later life, unless protected by re-vaccination.
What, then, must they think of the law which requires that a like foul virus shall be perforce injected into their own veins, to befoul the whole current of their blood and to introduce all manner of diseases? “But care is taken to have the lymph fresh and pure from the heifer,” say the vaccinationists.
1898 July 19, Mr. T. P. O'Connor (Liverpool, Scotland), “Commons Chamber: Clergy Mutual Assurance Society Bill Hl: Orders Of The Day: Vaccination Bill”, in House of Commons Hansard (House of Commons), volume 62, column 363:
Now, Mr. Speaker, I do not think, although I am a strong vaccinationist, that anybody in this House can deny that there is a considerable number of honest, earnest, and convinced opponents of vaccination in the country. […] You put the burden of proof practically on vaccinationists instead of putting the burden on those who oppose vaccination.

Jenner termed this procedure "vaccination" after the Latin word for cow. The vaccination had succeeded. Jenner made no secret of this initial success, and, although there were many skeptics, other practitioners joined the ranks of vaccinationists.

That smallpox could ravage London in the mid-nineteenth century, despite the existence of a new medical measure to prevent it, was a source of great frustration to the vaccinationists. In 1840 the epidemiologist William Farr railed against the fact that five children a day were dying of smallpox in London.
