At a press briefing on Tuesday, December 13, Hong Kong Chief Executive John Lee announced two new changes to the region’s COVID-19 prevention system that will effectively nullify the “0+3” self-isolation requirement for inbound travelers. The first adjustment is the scrapping of QR codes on the “Leave Home Safe” app before entering various premises. However, the government will maintain the vaccine pass, and proof of three inoculations with a COVID-19 vaccine will still be required to enter certain premises, such as restaurants. The second adjustment is the scrapping of the “amber code”, a code issued to all arrivals in Hong Kong that restricts people from entering public premises for a period of three days. Instead, everyone who tests negative for COVID-19 will be issued with a blue code in their vaccine pass which will give them free access to public places. The government had previously removed the requirement for travelers to take a PCR test upon arrival, and from Tuesday, December 13 onward only need to take a rapid antigen test (RAT). The new adjustments to the QR and amber codes will be effective from Wednesday, December 14 onwards.
