Hong Kong will complete an e-booking system for Covid-19 vaccine inoculations this month and is in talks with other countries to allow the records to be used for travel, local media from the region has reported.

The electronic-registration system will record when and which type of vaccine a person/citizen has received and will remind the user when to receive a second shot, Alfred Sit, secretary for innovation and technology was cited as saying in an interview.

Hong Kong has already reached agreements with Pfizer-BioNTech, AstraZeneca and China’s Sinovac Biotech to acquire 22.5 million potential doses of vaccines and is seeking a further 7.5 million. The government has said residents will be able to choose which type they receive, though the details are yet to be announced.

The Hong Kong government appointed a committee to approve the emergency use of the vaccines, chief executive Carrie Lam said last week, signalling the city is moving closer to authorising the candidates.

Hong Kong does not require all residents to screen for the virus but issued mandatory testing orders to tenants of 44 buildings where cases were found in the past 14 days.
