In line with the latest advisory, if you are unvaccinated, only visitors who are medically ineligible for any of the vaccines offered under the National Vaccination Programme will be allowed to enter attractions and other premises where Vaccination-Differentiated Safe Management Measures (VDS) are required (e.g. F&B establishments).
They will need to present either a hard copy memo issued by a General Practitioner (GP) clinic, public or private healthcare institution along with a government-issued photo identification card or their TraceTogether app for entry into these premises.
