HC Deb 22 November 1977 vol 939 c660W
38. Miss Joan Lestor

asked the Secretary of State for Social Services how many infants under three months of age and under six months of age, respectively, were vaccinated against whooping cough in the years from 1970.

Mr. Ennals

Information on the numbers of children vaccinated against whooping cough is collected by my Department annually by year of birth of the child. Numbers of children vaccinated under three months of age and under six months of age are not separately identifiable.
