§ Dr. Stross
asked the Minister of Health the morbidity rate of the present influenza epidemic, in schools, in factories, and generally; and what experiments are being conducted with a view to offering immunity to the public.
§ Mr. Iain Macleod
Influenza is not a notifiable disease and accurate morbidity rates cannot be calculated, but from other information it appears that the present outbreak is of a mild type. Investigations into immunisation against influenza have been carried out by the Medical Research Council for some years, and trials of experimental vaccines are now in progress.
