John C. McVail
Extract
Closely interlinked with the subject of a Revaccination Act is that of the Conscience Clause. When the Royal Commission on Vaccination published its final report and boldly recommended a Conscience Clause, a great part of the medical profession and probably also of the public were startled at what they regarded as a lowering of the vaccination flag. Some opponents of vaccination appeared at first to be jubilant over what they professed to regard as an antivaccination victory. . .
