§ Major Markhamasked the President of the Board of Trade whether he is aware that stocks of toys are being held in Curry's warehouses at Leicester; and 1372W estimated that the average number of immunised children under the age of 15 in 1943 was about 700,000. Correspondingly, the number of non-immunised children in 1943 would be 540,000, not 400,000 as stated in the Summary Report. These figures make no allowance for the unknown but relatively small number of immunisations performed by private doctors outside local authority arrangements. In place of the incidence rates quoted in that Report, therefore, it appears that approximately one in every 160 non-immunised children took diphtheria during 1943, as compared with only one in every 430 immunised children. The case mortality rates quoted in the Report, of one death in 18 cases for non-immunised children as compared with one death in 163 cases of immunised children, are not affected by this adjustment. The adjusted figures contained in this reply will be published in next year's Report.
