Anti-Typhoid Inoculation

Y object in reading this paper is to point out clearly some of the splendid opportunities for the application of anti-typhoid inoculation in civil life. Then later, by briefly quoting some of the results already obtained, I hope to accomplish the dual purpose of substantiating the claims made for it, and creating a wholesome confidence that will result in bringing this prophylactic into its proper place in preventive medicine. Some may consider that an apology would be in order for writing on a subject so widely discussed and in some of its phases so well understood. But, unfortunately, many have refrained from realizing a practical experience with anti-typhoid vaccine; their knowledge of the subject being limited to a well memorized statistical statement of its value in the armies of the world.

This consists of injecting a definite number of dead typhoid bacilli into the subcutaneous tissue of the body, with the object of rendering the one so injected immune to typhoid fever. A tremendous amount of evidence has been accumulated which proves beyond a doubt that this process does confer immunity from typhoid to an extraordinary degree. Major Russell of the United States Army has said that "Anti-typhoid inoculation protects against typhoid to a greater extent than does vaccinia against variola." It may be worth while to refresh your memories with a few of the results obtained from its use in mlilitary life. Quoting from the Anti-typhoid Committee's Report to the British Army, 1912, "The histories as regards typhoid fever, of 19,314 soldiers, whose average period of service abroad was twelve
