On the continent every effort is made to secure aseptic lymph. Its asepticity can not be otherwise than probable, until the specific germ or tox-albumen of cowpox shall be isolated, and a laboratory product placed upon the market. However, it is not unreasonable to now require that a vaccination abrasion be treated as is any other abraded surface, viz: aseptically. Since the vitiation of bovine virus by twenty or more demonstrable germs can not as yet be excluded, added infection from skin and air can, at least, be prevented by the antiseptic preparation, operation and dressing of the arm.
Should an ulcer, erysipelas, lymphangitis or phlegmon appear, treat each as you would surgical complications elsewhere. Granting them to be infectious, it follows that their invasion and effects must be minimized.
