Secretary for the Civil Service Patrick Nip Tak-kuen, the minister in charge of the city's Covid-19 vaccination program, said the vaccination rate among the elderly remains low, with just 30 percent of those aged over 70 having received a dose.

Nip said the government will be introducing the mobile Covid-19 vaccine clinics late this month, rolling them out to different neighborhoods to administer the Covid jabs, especially to the elderly.

Meanwhile, when asked if he would be getting the BioNTech vaccine as his third jab, the civil service chief - who received both doses of the Sinovac jab, said he “will tell the public his choice of the vaccine once he got it”.

As for the other government officials, Nip said it is up to them to choose whichever vaccine they want.

He stressed that the government’s vaccine panel has already suggested that Sinovac recipients getting the BioNTech jab as their third dose will generate better protection against the coronavirus.
