§ Mr. A. Edwards
asked the Secretary of State for War whether the Army Medical Department uses the word "immunity" to mean protected from a disease; or what is the meaning of the word in reference to vaccination and the various inoculations.
§ Sir J. Grigg
The term "immunity" is used by the Army Medical Department to describe the effects of protective treatment against certain diseases. There are degrees of immunity which necessarily vary in accordance with certain factors, for example, the resistance of the patient to a particular parasite.
