ON THE ANTI-RABIC VACCINATION IN THE DOG

Abstract

1. Of various vaccines which were prepared and tested on animals in the laboratory, the one prepared by incubating the emulsion of the brain and cord from animals infected with fixed virus at 37°C. for 3 days or that prepared by keeping the emulsion at room temperature for 10 days is most applicable for the vaccination in the dog.2. The vaccine prepared by incubating the emulsion at 37°C. is better than that prepared by keeping it at room temeprature, because more uniform attenuation of the virus could be expected in the former treatment.3. As the source of the vaccine the brain and cord of the dog is better than those of rabbit, because the yield in the former is six times more than that in the latter.4. In the dog the vaccine is to be once inoculated subcutaneously in dose of 5c.c.5. The immunity produced by the vaccination lasts for about one year.
