The article on Vaccination in the Encyclopedia Britannica, in the old edition preceding the last or current edition, was written by Dr. Chas. Creighton of London, a well known English doctor who, by long study, has become an opponent of vaccination, and is the author of several books exposing its fallacies. When Dr. Creighton first got the commission to write the article for the Encyclopedia he was a pro-vaccinist, like many other doctors, but to fit himself to write a full and impartial article which would give both sides of the subject he resolved to make a thorough study of it, pro and con. This study convinced him of the dangerous nature of vaccination to health and life, its limited or exaggerated value as a protection against smallpox, and its illogical or unscientific basis as a medical remedy; and his critical article on this subject, when it first appeared in the leading Encyclopedia, made a sensation in the medical world and has been a thorn in the side of pro-vaccinists ever since. Now, what will impartial students of this subject say when I cite the fact that the article on Vaccination in the last or current edition of the Britannica is written, not by a man who is impartial and professionally disinterested in the subject, as was Dr. Creighton, and who tried to give both sides of the subject freely, but, on the contrary, by a man who is actually _a manufacturer or inventor of vaccine virus_ and has, therefore, necessarily, a professional interest and bias to conceal the failures and dangers of vaccination as far as he can? Surely, the editors of the Britannica made a great moral and logical mistake when they selected any man to write so important an article on a much disputed subject in this great book of reference who had any professional or other interest or bias in this subject. Now, the biased and interested author of this article in the last edition is none other than Dr. S. Monckton Copeman of London, a strong pro-vaccinist, who claims to be the original inventor of the so-called “_glycerinated virus_” now in general use for vaccination. The idea of adding glycerine to the virus is to kill the many dangerous disease germs or infections it is known to contain, but to preserve the germ of smallpox, or “cowpox” intact. This is, of course, an admission that before the use of glycerinated virus vaccination was very dangerous and likely to cause many infections in the human body, but since the adoption of glycerinated virus--Dr. Copeman’s invention--it is now claimed that vaccination is rendered safe and harmless. This is, of course, a false claim, as I have already shown, and will further show in a succeeding paragraph.
