protection can only be obtained by re-vaccinations repeated at frequent intervals of a few years! It will thus be seen that Jenner completely abandoned his false and reckless claim of _perfect protection_ from smallpox _for life_ by _one vaccination_, for which he got his big graft or money prize from the English government; but, please note, he did not make this retreat or acknowledge his great mistake until after he had pocketed his big reward of thirty thousand pounds for his shamefully false claim of the unlimited protection and perfect safety of vaccination! SHORT DURATION OF VACCINAL PROTECTION AND NECESSITY OF FREQUENT RE-VACCINATIONS NOW ADMITTED. DANGER FROM SUCH REPEATED VACCINATIONS GREATER THAN FROM SMALLPOX We have seen in the preceding chapter how the original false and reckless claim of Dr. Jenner for _absolute protection for life from one vaccination_ was soon abandoned when put to the actual test of smallpox epidemics and that a modified position was then taken in the necessity of re-vaccination in certain periods of about seven years, more or less. This limited claim has, however, been also abandoned in recent years and the term of alleged vaccinal protection has been getting successively shorter and shorter, until it has now fallen to the ridiculously short protective period of only six months or a year for each vaccination or re-vaccination! This seems to be the present position of our most recent medical authorities and advanced vaccinators, which is not only a great shrinkage in protective claim but is very interesting and significant in that it closely approaches, and admits, the rational position of the anti-vaccinators who have contended consistently and persistently from the days of Jenner that vaccination, at the best, gave merely a limited immunity of only a few months, more or less, and, in some cases, in very susceptible persons, gave no immunity; and that frequent and repeated vaccinations are more dangerous as being multiple and cumulative infections of an artificial or inflicted disease than beneficial as the preventive of a natural disease. To show the present position of advanced pro-vaccinators on this point and their virtual agreement with anti-vaccinators as to the very limited period of vaccinal protection and the necessity of frequent repetitions, I will now quote from a recent high medical authority, viz., Dr. Robert Olesen, of the U. S. Public Health Service, stationed at Manila in the Philippine Islands, which is supposed to be one of the greatest fields in the world for practical experience with smallpox and vaccination. In an elaborate article by Dr. Olesen printed in the _New York Medical Record_ of March 4, 1911, he makes these very serious statements as to the necessity of frequent re-vaccinations and the short duration of protection from each vaccination, as follows:
