At least seven people fell ill after receiving Chinese Sinovac vaccine shots in Hong Kong city, media reports said.
Two of the people were reportedly put in intensive care.
This means a total of 18 people have sought medical attention after receiving the vaccines over the past week, based on a tally of government data, or 0.019 per cent of the approximately 91,800 people who had taken the mainland-produced jabs so far, reports South China Morning Post.
China is believed to be the nation from where COVID-19 virus spread across the globe.
