HC Deb 01 February 1955 vol 536 c104W
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

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.
