Abstract
IN opening a discussion on immunity to viruses in the Section of Comparative Medicine of the Royal Society of Medicine on April 21, Sir John Ledingham said that notwithstanding the immense amount of attention paid in the last twenty years to immunization against virus diseases, Jenner's discovery still remains the touchstone by comparison with which all subsequent efforts in this field must be judged. All attempts at immunization against viruses present the same problem-the preservation in the vaccinating agent of the maximum antigenicity compatible with safety from both immediate and remote sequelæ. The solution of this problem has proved no easy matter and there is still a large field to explore in the exploitation of natural variants of pathogenic viruses of man and animals.
