§ Mrs. Tateasked the Minister of Health what action is being taken by his Department to meet what the Rolleston Vaccination Committee in their second report in 1930, described as the urgent necessity of trying to find some means of protection against small-pox other than that of the direct introduction of a living virus into the organism?
§ Sir K. WoodExperiments were carried out in 1929 and 1930 at the Freedom Research Laboratories of the London Hospital, with financial assistance from my Department, to test what immunity, if any, could be produced by in- 225W activated vaccinia virus. A report was published in the "Journal of Hygiene" for January, 1932. I am advised that, though slight immunity was produced in some cases, the results of the experiments give little assurance that solid immunity can be produced in this way.
