China National Biotec Group (CNBG) and Sinovac Biotech said on Saturday four more countries have agreed to run late-stage clinical tests of their coronavirus vaccine candidates, as China steps up its efforts in the global race.
Serbia and Pakistan are among the new countries agreeing to Phase 3 trials, as the two companies seek more data overseas amid dwindling new cases in China.
Serbia will test two vaccines developed by CNBG’s Wuhan and Beijing units, and Pakistan will test the Beijing unit’s candidate, the company told Reuters.
CNBG’s Phase 3 trials are expected to involve 50,000 people in about 10 countries, said CNBG vice president Zhang Yuntao. Trials have already begun in United Arab Emirates, Bahrain, Peru, Morocco, Argentina and Jordan.
Zhang said foreign countries have expressed interest in ordering a combined 500 million doses of its vaccines.
CNBG is expected to be able to produce 300 million doses of vaccine a year once it upgrades manufacturing techniques, and is working on a plan to raise its annual capacity to 1 billion doses, Zhang said.
