Those aged 6-15 only need to submit this COVID-19 test.

Modes C and D are the new arrangements introduced under the Government's "vaccine bubble", with Modes A and B being previously in place. A catering business (excluding bars and pubs) can designate the whole or part of a premises as "Designated Zone C" and/or "Designated Zone D", provided within each of those zones they comply with the respective rules relating to the mode of operation.

Business operators can now download a mobile app (currently only available on Android phones) from the Food and Environmental Hygiene Department to inspect customers' vaccination records. Details as to the installation of the app can be found here:
