Clause 26

Every person on an international voyage whether leaving or arriving in Singapore shall have been vaccinated against any or all of the diseases in accordance with the requirements set out in the Third Schedule and shall produce valid international certificates of vaccination to a Port Health Officer.

Notwithstanding subsection (1) a Port Health Officer may require such person to be vaccinated and may subject him to isolation or surveillance for such period as the Port Health Officer thinks fit.

The Port Health Officer may in his discretion return any person, not being a citizen of Singapore, who refuses or fails to comply with subsection (2), to his place of origin or embarkation at the expense of the owner or agent of the vessel by which he arrived in Singapore.

The owner, master or agent of any vessel shall ensure compliance with the provisions of subsection (1) in respect of any person on board his vessel.
