HONG KONG — Hong Kong health officials say quarantine rules for inoculated travelers arriving in Hong Kong from low- and medium-risk countries will be relaxed.

Inbound travelers who have been fully vaccinated from low-risk countries like Australia, New Zealand and Singapore will only need to undergo seven days quarantine in a hotel, down from 14 days previously. They will also need to take two coronavirus tests after their quarantine.

Those coming from medium-risk countries, such as Malaysia or Vietnam, will have their quarantines reduced to 14 days, from 21 days. Arrivals from high-risk countries, such as the U.S., Britain and other European countries like Germany or France will still have to undergo three weeks of quarantine, regardless of their vaccination status.

The new measures will take effect from May 12.

Hong Kong is seeking to boost its slower-than-expected vaccination rates in the city. Hong Kong has so far only vaccinated about 13.6% of its population, amid public distrust of the largely pro-Beijing government and concerns over side effects.

On Friday, officials also announced the reduction of quarantine periods for close contacts of coronavirus patients who have been fully vaccinated.
