Iran Press/Asia: A Sinovac spokesman said the third facility, in Beijing, had started cultivating cells where the coronavirus would be grown, a procedure that could take a relatively long time.
Sinovac did not say when it will actually produce 2 billion doses of the vaccine.
More than 200 million doses of Sinovac’s vaccine named CoronaVac have been delivered globally, up from 160 million doses announced on March 22.
The firm said it estimated over 100 million doses have been administered worldwide.
