Experimental Study of Intraaxillary Vaccination of B. C. G

Abstract

I can resolve the question of why the local lesion does not occur when B. C. G. is vaccinated intraaxillarily. The reasons are the following.
1. B. C. G., which is inoculated into the intraaxillary region, seems to be absorbed by way of the blood capillaries as well as lymphatic capillaries.
2. In the intraaxillary region there is a large hole which has a spongy construction and well-developed lymph vessels and blood vessels.
3. The substances (bacteria, dyes) which are inoculated into the intraaxillary region, are absorbed so readily, rapidly, and easily that the local lesion does not occur.
