I say that small-pox is a pest; it is worse than the plague, for if not kept in subjection it is more general—sparing neither young nor old, rich nor poor, and commits greater ravages than the plague ever did. Small-pox is a disgrace; it is a disgrace to any civilized land, as there is no necessity for its presence: if cow-pox were properly and frequently performed, small-pox would be unknown. Cow-pox is a weapon to conquer small-pox, and to drive it ignominiously from the field.

My firm belief then is, that if every person were, every seven years, duly and properly vaccinated, small-pox might be utterly exterminated; but as long as there are such lax notions on the subject, and such gross negligence, the disease will always be rampant, for the poison of small-pox never slumbers nor sleeps, but requires the utmost diligence to eradicate it. The great Dr. Jenner, the discoverer of cow pox as a preventative of small-pox, strongly advocated the absolute necessity of every person being revaccinated once every seven years, or even oftener, if there was an epidemic of small-pox in the neighborhood.

48. Are you not likely to catch not only the cow-pox, but any other disease that the child has from whom the matter is taken?

The same objection holds good in cutting for small-pox (inoculation)—only in a tenfold degree—small-pox being such a disgusting complaint. Inoculated small-pox frequently produced and left behind inveterate “breakings-out,” scars, cicatrices, and indentations of the skin, sore eyes, blindness, loss of eyelashes, scrofula, deafness—indeed, a long catalogue of loathsome diseases. A medical man, of course, will be careful to take the cow-pox matter from a healthy child.

49. Would it not be well to take the matter direct from the cow?

If a doctor be careful—which, of course, he will be—to take the matter from a healthy child, and from a well-formed vesicle, I consider it better than taking it direct from the cow, for the following reasons: The cow-pox lymph, taken direct from the cow, produces much more violent symptoms than after it has passed through several persons; indeed, in some cases, it has produced effects as severe as cutting for the small-pox; besides, it has caused, in many cases, violent inflammation and even sloughing of the arm. There are also several kinds of spurious cow-pox to which the cow is subject, and which would be likely to be mistaken for the real lymph. Again, if even the genuine matter were not taken from the cow exactly at the proper time, it would be deprived of its protecting power.

50. At what age do you recommend an infant to be first vaccinated?

When he is two months old, as the sooner he is protected the better. Moreover, the older he is the greater will be the difficulty in making him submit to the operation, and in preventing his arm from being rubbed, thus endangering the breaking of the vesicles, and thereby interfering with its effects. If small-pox be prevalent in the neighborhood, he may, with perfect safety, be vaccinated at the month’s end; indeed, if the small-pox be near at hand, he must be vaccinated, regardless of his age and regardless of everything else, for small-pox spares neither the young nor the old, and if a new-born babe should unfortunately catch the disease, he will most likely die, as at his tender age he would not have strength to battle with such a formidable enemy. “A case in the General Lying-in-Hospital, Lambeth, of small-pox occurred in a woman a few days after her admission and the birth of her child. Her own child was vaccinated when only four days old, and all the other infants in the house, varying from one day to a fortnight and more. All took the vaccination; and the woman’s own child, which suckled her and slept with her; and all escaped the small-pox.”[[155]]

51. Do you consider that the taking of matter from a child’s arm weakens the effect of vaccination on the system?

Certainly not, provided it has taken effect in more than one place. The arm is frequently much inflamed, and vaccinating other children from it abates the inflammation, and thus affords relief. It is always well to leave one vesicle undisturbed.
