Hundredsof thousands of people in China have been given a coronavirus vaccine despite the fact it has not been finally approved by regulators.
The move has prompted concerns among onlookers that China is pushing ahead to gain an edge in the race to develop a successful vaccine without following proper safety measures.
Chinese companies Sinopharm and SinoVac have given vaccine shots to more than 350,000 people in recent months and that number is likely set to rise.
The inoculations have been performed under an emergency use designation that was approved in June.
SinoVac has also provided tens of thousands of rounds of its CoronaVac for the Beijing city government.
Another candidate being jointly developed by the military and CanSino, a biopharmaceutical company, has been approved for emergency use in military personnel.
