Article 31 Health measures relating to entry of travellers (pg 24 IHR 2005)
2. If a traveller for whom a State Party may require a medical examination, vaccination or other
prophylaxis under paragraph 1 of this Article fails to consent to any such measure, or refuses to

(b) vaccination or other prophylaxis; or
(c) additional established health measures that prevent or control the spread of disease,
including isolation, quarantine or placing the traveller under public health observation.
