Chinese vaccines are poised to fill gap, but will they work?

For those countries that have not yet secured a vaccine, China may be the only solution.

China has six candidates in the last stage of trials and is one of the few nations that can manufacture the vaccine on a large scale. Government officials have announced a capacity of one billion doses next year, with President Xi Jinping promising China’s vaccines will be a boon to the world…

Yet past scandals have damaged its own citizens’ trust in its vaccines, with manufacturing and supply chain problems casting doubt on whether it can really be a saviour.

“A question mark remains over how China can ensure the delivery of reliable vaccines,” said Joy Zhang, a professor who studies the ethics of emerging science at the University of Kent in Britain. She cited China’s “non-transparency over scientific data and a troubled history with vaccine delivery”.
