§ Mr. GROVESasked the Minister of Health if he will request the Committee which he has appointed to report from time to time on matters relating to vaccination to furnish him in their First Report with replies to the following queries: what is the precise nature of the disease from which vaccine lymph is derived and how is its nature determined; what is a successful and efficient vaccination and for how long can it be guaranteed to remain so; how frequently has it been found possible to repeat vaccination on the same person; what is the relation of the possibility of frequently repeating vaccination to the question of immunity; and what means are recommended for ascertaining whether the immunity afforded by vaccination has lapsed?
§ Sir K. WOODMy right hon. Friend will communicate these suggestions to the Committee on Vaccination for their consideration.
