c. 84) consolidated and updated the existing laws relating to vaccination, and was repealed by the National Health Service Act 1946.

The Act also provided that any person who produced or attempted to inoculate another with smallpox could be imprisoned for a month.

This act also confirmed the principle of compulsion, which evidently sparked hostility and opposition to the practice.

c. 75) clarified the role of the Local Government Board in making regulations for guardians to implement the 1871 act.

It removed cumulative penalties and introduced a conscience clause, allowing parents who did not believe vaccination was efficacious or safe to obtain a certificate of exemption.

Under this law the parent escaped penalties for the non-vaccination of his child if within four months from the birth he made a statutory declaration that he confidently believed that vaccination would be prejudicial to the health of the child, and within seven days thereafter delivered, or sent by post, the declaration to the Vaccination Officer of the district.
