Experiments in Connexion with an Attempt to Produce a Neurotropic Strain of Vaccinia Virus in Sheep

Abstract
The experiments now described were carried out in Lagos and Khartoum, and although the hoped-for end-result, the production of a sheep strain of neurovaccinia, was not realized, certain points of interest have arisen and are recorded in the hope that they may be of help to other workers concerned with vaccinia vaccine production.
