§ Dr. Roger Thomasasked the Secretary of State for Social Services if, in view of the incidence of adverse reactions to the present vaccine, he has any plans to introduce an acellular pertussis vaccine.
§ Mr. Kenneth ClarkeThe vaccine being developed at the centre for applied microbiology and research with support from this Department is acellular. As I indicated in my reply to the hon. Member for Dundee, West (Mr. Ross) on 27 October 1982—[Vol. 29, c.435]—progress is satisfactory.
