CORONAVIRUS | A potential Covid-19 vaccine being developed by Chinese researchers showed promise in trials in monkeys, triggering antibodies and raising no safety issues, researchers said, and a human trial with more than 1,000 participants is underway.

The vaccine candidate, called BBIBP-CorV, induced high-level neutralising antibodies that can block the virus from infecting cells in monkeys, rats, guinea pigs, and rabbits, researchers said in a paper published online by the medical journal Cell on Saturday.
