So committed and so possessed, Hill naturally resented the growing distrust of vaccination. It cut him deeply to be supposed a quack; and in 1806 he issued a pamphlet[173] relating his experiences as a Jennerite, defending his practice, and denouncing those who treated it despitefully. Moseley especially was subjected to severe and contemptuous condemnation. Hill’s sanctimony and virulence, his vigour and venom compose a piquant mixture, and if we could tarry for amusement we might produce it abundantly from a variety of elegant extracts. Consider, for instance, this his adjuration, and its pitiful object-- Oh, the blessing of the Jennerian inoculation! Did ever man stand as Jenner so much like an Angel of God, an instrument in the hands of Divine Providence between the living and the dead till the plague was stayed! Hill’s latent assumption throughout his discourse was-- First, that all must have smallpox; and Second, that all the vaccinated who escaped smallpox, owed their salvation to their Jennerisation. It never apparently occurred to him that before Jenner was heard of, many passed through life exempt from smallpox; nor, consequently, did he inquire _how_ they escaped; nor _why_, when vaccination was introduced, escape should be placed to its credit. The belief in the vicarious influence of vaccination comes out strongly, too, in Hill’s pamphlet. Of Londoners there were then over 1,000,000, and of these, he says, at least, 100,000 had been vaccinated, and with this effect-- Vaccination reduced the deaths from Smallpox in London to 10 per week; but after the Inoculators had been making their clamours, the applicants for Vaccination diminished, and the deaths soon rose to 100 per week. Now can effrontery itself deny that the introduction of Vaccination was the sole cause of reducing the fatality on the Smallpox list? Thus one in ten being vaccinated, smallpox was reduced throughout the unvaccinated 9-10ths; and as soon as the vicarious operations dropped, up went the rate of mortality! Nor was Hill singular in this persuasion. He cited his friend Dr. Lettsom as writing to him, 25th March, 1806-- Vaccination was gradually lessening the mortality in 1804, when about the middle of 1805 false reports against Vaccination gained very general credit, and Vaccination was nearly suspended; the consequence was the death of 1286 children in four months (September to December) or ten every day, each of whom might now have been alive had the blessing of Vaccination been accepted. And again I find Lettsom wrote to Moseley, November, 1808-- The increase of births and decrease of deaths has added 3000 lives annually to the population of London during the period that Vaccination has been practised. Talk evidently sincere, and widely repeated, but with how little consideration for truth!
