§ 77. Mr. Awberyasked the Minister of Health what examination is being made into the causes and prevention of poliomyelitis, other than by injection of vaccine; and to what extent the tests made of United States and Canadian Salk vaccine are more or less severe than the tests made on similar vaccines in Great Britain.
§ Mr. Walker-SmithIn addition to the epidemiological investigations that are made when cases of poliomyelitis occur, research is proceeding all the time into various aspects of the disease and its prevention. A highly technical and complicated matter like comparison of the various testing procedures cannot readily be dealt with within the scope of a Parliamentary Answer, but I dealt with the subject of testing Salk vaccine very fully in the debate in the House on 1st May, and perhaps the hon. Member would refer back to what I said on that occasion.
