CHAPTER VIII 



VACCINES AND THEIR MODE OF 

 PREPARATION 



From the previous chapter it will be gathered that within 

 the animal body certain protective forces exist, which, 

 should a bacterial invasion occur, become offensive in their 

 action, and wage war against the invading germs. This 

 warfare is taking place daily in every human and animal 

 body. Sometimes these antibodies are so strong and active 

 that complete protection takes place, and no disturbance 

 is made manifest. At other times the cardinal symptoms 

 of disease present themselves, and after running their 

 course recovery takes place, and the leucocytes and anti- 

 bodies are thereby fortified. In other cases the bacteria or 

 their products disintegrate, and destroy Nature's protective 

 antibodies, with consequent dissolution of the animal. 



Medicinal preparations have long held sway in com- 

 bating disease, but how many practitioners of medicine are 

 there who are absolutely satisfied with the curative values 

 of drugs in specific bacterial diseases ? Nay, more, the 

 longer they are prescribed, the more apparent do their 

 limitations become. 



Vaccine-therapy not only carries the therapeutist beyond 

 this limited field, but in many cases he supplants the 

 medical therapeutist altogether, and that, too, often to the 

 great advantage of the patient. Moreover, the logic of 

 vaccine-therapy is based upon a sound reasoning founda-

 and endeavouring to effect a cure in the same way as 

 Nature herself ; and in those cases where Nature, usually
