Excerpt from The Preparation of a Safe and Efficient Antirabic VaccineIt is now well established that dead bacterial vaccines are efficient in producing an immunising response in man and animals a response which in most cases it would not be justifiable to attempt to produce with living bacteria. On this account it is now almost the universal custom in the prophylactic and cura tive vaccination Of infectious diseases in man to make use of killed cultures of the causal micro-organisms. No person would be justified in using a living staphylo coccus, or a living streptococcus vaccine, when dead vaccines prepared from these germs answer every purpose.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
