China National Biotec Group (CNBG) and Sinovac Biotech Ltd 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.
