An epidemic of smallpox of unexampled severity began at the end of the year 1870, “the like of which had not been known in England since vaccination was first practised.” It increased in London at an alarming rate until it reached its height in May, 1871, when 288 people died of it in one week, and it killed in London alone, in that one year, 7,876 persons. And as it was reasonable to assume that one death represented at the very least eight or ten times the number of cases of that most loathsome disease, the results were frightful, and the injury inflicted upon the community, present and future, disastrous.
At one time more than 2,000 smallpox patients were under the care of the Metropolitan Asylums Board, and the admissions into the Board’s hospitals about the same time averaged 500 a week.
In a report on the subject the Committee of the House of Commons wrote:—
“It is impossible to say what ravages might not have been the result of the smallpox epidemic of 1870–1 had it not been for the efficiency and energy of the Asylums Board. Although the prophylactic virtues of vaccination have been recognised on all sides, it must be remembered that as yet but a small part of the growing population has been subjected to the operations of the Compulsory Vaccination Act.”
And they expressed “their strong sense of the great services rendered to the metropolis by the managers.”
The prevention of smallpox by vaccination was not yet a very potent factor in the diminution of that disease. Only slowly could the Compulsory Vaccination Act of 1867 produce effect, and as the appointment of public vaccinators and the establishment of vaccination stations had been made only optional, the mortality of the outbreak in 1870–1 had been but little, if at all, modified by it. The epidemic, however, was used by some to enforce a lesson.
Thus the Medical Officer of Health for St. James’ wrote:—
“The lesson of the great epidemic of smallpox is the necessity for vaccination.
“The history of no other disease supplies so assuredly and necessarily the means of its entire destruction.”
And the managers of the Metropolitan Asylums Board, in a report issued in 1871, wrote:—
