§ Mr. Viantasked the Minister of Health what evidence he has that convalescent vaccinia serum is no longer of use in cases of generalised vaccinia associated with severe toxaemia; and whether it is no longer available from the Public Health Laboratory Service.
§ Mr. TurtonI am informed that recovery from generalised vaccinia after treatment with convalescent serum has been reported occasionally. Recently gamma globulin, the concentrated active fraction from this serum, has been used and is now available from the Public Health Laboratory Service in place of whole convalescent serum.
