§ Mr. Viantasked the Secretary of State for Scotland what is the percentage deducted from the returns of immunised 545W children sent in by medical officers of health to allow for those children who pass the age limit of 15 years.
Mr. JohnstonThe figures supplied by Medical Officers of Health are cumulative and the deduction to allow for children passing the age of 15 therefore gradually increases. It would not be possible without considerable labour to give precise figures of the number of children involved, but the appropriate deductions for the years 1941, 1942 and 1943 were estimated to be 4 per cent., 9 per cent. and 15 per cent. respectively.
