IV.—It is further said that nurses in smallpox hospitals never contract smallpox because they are revaccinated.
To establish this assertion, it would be necessary to prove that prior to the introduction of vaccination, or rather of revaccination, it was common for nurses to fall victims to the disease. The attempt is not made, and wisely, for failure would be conspicuous. Jenner never recommended vaccination as a protective for nurses. Their general immunity, along with that of physicians, is noted throughout our older medical literature; nor is the reason far to seek. Smallpox is predominantly an affection of the young, and it is no more surprising that a nurse should be proof against it than that she should be proof against measles, whooping cough, or scarlet fever. Nurses occasionally incur these maladies, and they occasionally incur smallpox.
If revaccination preserves nurses from smallpox, to which they are exposed in the intensest form, it should much more preserve soldiers, sailors, policemen and postmen, whose exposure is incomparably less intense; yet these servants of the state (as already observed) are as liable to smallpox as their unrevaccinated fellow citizens of correspondent ages.
To speak plainly, the selection of a vocation so arduous and repulsive, marks off a smallpox nurse as unimpressionable, and little apt to catch anything. Smallpox, too, is like tobacco: custom fortifies the constitution against its immediate effects. If the atmosphere of a smallpox hospital is endured for a fortnight, it is likely to continue endurable. On the other hand, if a volunteer sickens on probation, she is not reckoned among nurses. Lastly, many nurses have entered hospitals as patients, and have accepted service in default of other occupation. On these grounds, the nurse argument breaks down irretrievably. At first sight, it seems something, but on scrutiny it proves nothing.
POCK-MARKED FACES.
V.—Another favourite argument for vaccination is the disappearance of pock-marked faces. People say when they were young such faces were common, whilst now they are rare; and demand, What can have wrought the change if not vaccination?
A medical man at a public meeting tried to dispose of some statistics adverse to vaccination by saying that statistics could be made to prove anything; and presently went on to relate that when his mother was a girl every third person she met was pock-marked. She had told him so repeatedly, and there was no doubt about her accuracy. Thus statistics in general were untrustworthy, but his mother’s statistic was unquestionable.
We need not hesitate to allow that when smallpox was common and cultivated pock-marked faces were more numerous: but we must not forget that whether a patient is marked or not marked is very much a matter of treatment. Many at this day pass through smallpox, and severe smallpox, and escape unmarked, simply because those who have care of them observe certain precautions. It was different in former times. The treatment of smallpox was atrocious. The sick-room was made pestiferous by the exclusion of air and the maintenance of high temperature. The patient sweltered under bed-clothes. He was neither allowed to wash nor change his linen. He was drenched with physic and stimulants. In hospitals, patients were stuck two or three in a bed, and stewed together. If, under such circumstances, the sick were restored to life pock-marked, what wonder! Patients who were fortunate enough to be sufficiently let alone, stood the best chance of recovery.
Besides smallpox was not equally diffused. In some places it was endemic; in others it appeared at intervals; and in others it was hardly known. The smallpox death-rate of Glasgow was double that of London; and we may therefore infer that pock-marked faces were twice as numerous in Glasgow as in London. Hence when recollections are appealed to, they should be localised. What might be true of one population might be grossly untrue of another.
