The Origin of Vaccine Inoculation. London: 1801.
1801.—It now becomes too manifest to admit of controversy, that the annihilation of the Small Pox, the most dreadful scourge of the human species, must be the final result of this practice.—P. [183].
Petition for Remuneration to House of Commons. 1802.
1802.—Cow Pox admits of being inoculated on the human frame with the most perfect ease and safety, and is attended with the singularly beneficial effect of rendering through life the persons so inoculated perfectly secure from the infection of the Small Pox.—Pp. [184], [337], [355].
On the Varieties and Modifications of the Vaccine Pustule occasioned by an Herpetic State of the Skin. Printed in Medical and Physical Journal, August, 1804; and reprinted as a pamphlet, Cheltenham, 1806, and Gloucester, 1819.—P. [340].
VACCINATION EQUAL TO VARIOLATION.
1804.—What I have said on Vaccination is true. If properly conducted it secures the constitution as much as Variolous Inoculation possibly can.—Baron’s Life of Jenner, vol. ii. p. 15.
Duly and efficiently performed, Vaccination will protect the constitution from subsequent attacks of Small Pox as much as that disease itself will. I never expected that it would do more, and it will not, I believe, do less.—Ibid. p. 135.
1806.—The security given to the constitution by Vaccine Inoculation is exactly equal to that given by the Variolous. To expect more from it would be wrong. As failures in the latter are constantly presenting themselves, we must expect to find them in the former also.—Letter to Richard Dunning, 1st March, 1806.—Pp. [339], [355].
