MR. RIGBY’S PROTEST.
There was in those days a surgeon of eminence in Norwich, Edward Rigby, and he at once entered his protest against the novel doctrine. Writing to the Medical and Physical Journal of August, 1814, he said, “No physiological reason is assigned for this, and I believe it would be difficult to prove that a single perfect vesicle, which goes through the usual stages and exhibits the characteristic appearances of this singular disease, can be less the effect of a constitutional affection than any given number would be.... It cannot surely be doubted that a single perfect vesicle affords as complete security against Variola as any indefinite number; and, if so, there would seem to be an obvious objection to unnecessarily multiplying the vesicles, which in all cases go through a high degree of inflammation, are often attended with painful tumefaction and even suppuration in the axilla, and, if exposed in the later stages to any act of violence, are apt to assume a very disagreeable ulceration, more especially as young children, now the principal subjects of vaccination, are most liable to suffer in this way.” Rigby had the better side of the argument. As he observed, no physiological reason was assigned for the recommendation of plural punctures; nor was any such reason ever assigned. It is the rationale of vaccination that a virus is injected into the system which begets a fever equivalent to an attack of smallpox; and as smallpox rarely recurs in a lifetime, it is hoped that Nature may graciously recognise the substitute for the reality. Organic poisons such as vaccine operate like fire or ferment. Quantity is of no account. So that the fever be kindled, excess is waste. A scratch at a dissection is as deadly as a gash. One bite of a mad dog is as likely to beget hydrophobia as a dozen. The sting of a cobra may be almost invisible, but the puncture is enough for death. Sir James Paget says of vaccine virus that “inserted once, in almost infinitely small quantity, yet by multiplying itself, or otherwise affecting all the blood, it alters it once for all.”
Such is the rationale of vaccination, and if I were a vaccinator, I should hold the position assumed by Rigby, and maintain that one puncture is as effective as a dozen, inasmuch as with one it is possible to excite that fever which is the essential of vaccination; adding, in Rigby’s words, that as one puncture is in all cases attended with a high degree of inflammation, and often with painful tumefaction, and even suppuration in the arm-pits, which in case of violence are apt to pass into very disagreeable ulceration, especially in young children, it is most undesirable to increase the number of such dangerous wounds.
