CULTIVATION OF VACCINE VIRUS FOR JENNERIAN PROPHYLAXIS IN MAN.
1. A dermal strain of vaccine virus has been adapted to a simple culture medium consisting of minced chick embryo suspended in Tyrode's solution. 2. The bacteria-free culture virus, thus obtained, produces in lower animals and in man typical vaccinia that renders them refractory to infection with ordinary vaccine virus harvested from calves.
