A Hong Kong government advisory panel suggested the city could shorten hotel quarantine periods for some fully vaccinated inbound passengers, in what would mark an easing of some of the world’s strictest COVID-19 restrictions for travelers.

Inoculated people who have tested negative for the virus and are coming from countries not classified as "high-risk” should qualify for a seven-day hotel quarantine, David Hui, a member of the government’s scientific committee, said at a briefing Wednesday evening. The proposed exemption would require a positive antibody test result conducted in Hong Kong after arrival, he said.

"The purpose of checking the antibody is to show evidence of response to vaccination,” the panel said. "If the serology test result is negative, the shortening of the quarantine period could not be considered.”
