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

TAIPEI, Taiwan (AP) — With rich countries snapping up supplies of COVID-19 vaccines, some parts of the world may have to rely on Chinese-developed shots to try to conquer the outbreak. The question: Will they work?There is no outward reason to believe they won’t, but China has a history of vaccine scandals, and its drugmakers have revealed little about their final human trials and the more than 1 million emergency-use inoculations they say have been carried out inside the country already.Wealthy nations have reserved about 9 billion of the 12 billion mostly Western-developed shots expected to be produced next year, while COVAX, a global effort to ensure equal access to COVID-19 vaccines, has fallen short of i ts promised capacity of 2 billion doses.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 vaccine on a large scale. Government officials have announced a capacity of 1 billion doses next year, with President Xi Jinping vowing China’s vaccines will be a boon to the world.The potential use of its vaccine by millions of people in other countries gives China an opportunity both to repair the damage to its reputation from an outbreak that escaped its borders and to show the world it can be a major scientific player.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 savior.“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.”Bahrain last week became the second country to approve a Chinese COVID-19 vaccine, joining the United Arab Emirates. Morocco plans to use Chinese vaccines in a mass immunization campaign slated to start this month. Chinese vaccines are also awaiting approval in Turkey, Indonesia and Brazil, while testing continues in more
