§ Mr. Russell
asked the Minister of Health if he is aware that an oral vaccine against poliomyelitis has been developed in the Union of South Africa; and what are the prospects of its being available for use in Great Britain.
§ Mr. Walker-Smith
Yes. Decisions regarding the use in this country of oral poliomyelitis vaccine from any source must await the results of the Medical Research Council's trials to which I referred in my reply to my hon. Friend the Member for Nottingham, South (Mr. W. Clark) on 15th February.
