There have naturally been some curious discussions before the magistrates as to what is "conscientious" or not, but the operation of the so-called "conscience clause" has tended to the more harmonious working of the Vaccination Acts, though at the cost of a high proportion of unvaccinated persons in some towns of England. The act of 1907 repeals sec. 2 of the 1898 act and sub stitutes for the certificate of a magistrate a statutory declaration before a magistrate or commissioner of oaths, and abolished the 20 s. penalty for failing to have a child vaccinated, if exemption has been obtained. The Scots law is similar.
On July 31, 1928, there was published as a large Blue Book (Stationery Office, Cmd. 3148) the report of the committee set up by the minister of health to inquire and report from time to time on various matters connected with vaccination. The committee consisted of medical men, under the chairmanship of Sir Hum. phry Rolleston, and made several recommendations, the most im portant of which from the public point of view is that they consider "it is expedient now to make a trial of vaccination in one insertion in a manner calculated to produce as little discomfort as possible, and to urge strongly the necessity for re-vaccination in like manner at stated intervals."
