Production of a certificate, etc., as defence in a charge of neglect

In any prosecution for neglect to procure the vaccination of a child, it shall not be necessary in support thereof to prove that the defendant had received notice from the Registrar or any other officer in this respect, but if the defendant produces a certificate respecting such child as described in sections 151 (3) and 152 (1) of this Act, or the register of certificates respecting vaccinations kept by the Registrar as hereinbefore provided in which any certificate respecting such child is duly entered, the same shall be a sufficient defence.
