§ Mr. Viantasked the Minister of Health how many cases of poliomyelitis recorded in 1957 developed within one month, two months and three months of inoculation, respectively; and in how many cases the paralysis was in the inoculated limb.

§ Mr. Walker-SmithThere are records that poliomyelitis developed in 1957 in 8 (5 paralytic), 5 (2 paralytic) and 6 (3 paralytic) children in the first, second and third months respectively after two injections of poliomyelitis vaccine. In one case, which occurred in the first month, the child had paralysis affecting the inoculated limb. As I indicated during the debate on the supply of poliomyelitis vaccine on 1st May, there are several reasons why poliomyelitis may occur in vaccinated persons. It is not possible to identify the reason with certainty in the individual case.
