HONG KONG -- The second batch of about 1 million doses of COVID-19 vaccines produced by Sinovac was delivered to Hong Kong from Beijing on Thursday afternoon, the Hong Kong Special Administrative Region (HKSAR) government said.

Together with the 1 million doses delivered to Hong Kong in February, a total of about 2 million doses of the Sinovac vaccine have arrived in Hong Kong, according to the HKSAR government.

Soon after the arrival of the Sinovac vaccine in Hong Kong, working staff immediately carried out stringent checking and inspection on the vaccines to ensure that they comply with the product specifications and their transportation process follows the cold-chain requirements, the HKSAR government said.

Since Hong Kong launched a COVID-19 vaccination program on Feb 26, more than 400,000 people have received their first dose of vaccine.
