Writing on an online blog, Chan said that over 6,900 cross-border truck drivers received the first jab, about 98 percent of the 7,000 drivers in Hong Kong.

Cross-border drivers - who have been vaccinated with two Covid-19 doses for 14 days - can enter Shenzhen and Zhuhai with a negative Covid-19 result within 72 hours instead of being tested for coronavirus every day, the Transport Department announced earlier this month.

“Most of the active drivers would complete vaccination by the end of this month,” Chan said.

“It may have more flexibility to ease the mandatory test measure in the future.”

Nearly all of the 1,600 cross-border drivers and about 80 percent of frontline workers in cross-border ferries received the first jab vaccination, Chan added.

He also said that 75 percent of the 3,400 pilots in local airlines have made appointments or have received the first dose of the Covid-19 vaccine.

“The government will continue to conduct regular inspections for the workers in the maritime industry and Hong Kong International Airport.”

Regular Covid-19 tests will continue to be provided to taxi, minibus, and ferry workers.
