Mr. Moyle

The number of children aged 1 to 5 years inclusive who had whooping cough and were studied by Miller and Fletcher was 6,802.

Mr. Ashley

asked the Secretary of State for Social Services if he will estimate the proportion of all children aged 1 to 5 years who were fully immunised against whooping cough at the beginning of 1975; and if he will give the number of children, aged 1 to 5 years, who were reported by Miller and Fletcher in their study of whooping-cough cases between October 1974 and March 1975, as having caught whooping cough after being fully vaccinated; and if he will express this number as a percentage of the number of children aged 1 to 5 years catching whooping cough whose vaccination history is known.

Mr. Moyle

The number of children, aged 1 to 5 years inclusive in England and Wales, who were fully immunised against whooping cough by 1st January 1975 as a percentage of live births in the years 1969 to 1974, inclusive, was 74 per cent.

The number of children, aged 1 to 5 years, who were reported by Miller and Fletcher in their study of whooping cough cases between October 1974 and March 1975 as having caught whooping cough after being fully vaccinated was 2,862 which represented almost 59 per cent. of the total cases studied in this age group and whose vaccination history is known.
