Under China’s emergency scheme, hundreds of thousands from its masses have been given two experimental Covid-19 vaccines, as shared by a top official with a state-owned vaccine developer. He has also confirmed that none of the recipients of the vaccine has shown any side effects and didn’t get infected with the coronavirus. 

The information has been shared by Zhou Song, secretary for the commission for discipline inspection with China National Biotec Group. He has also said that the company’s two candidate vaccines will provide people with protection for up to three years. 

“Hundreds of thousands have taken the shot and no one has shown any obvious adverse effects or got infected,” Zhou told China National Radio, adding that his firm’s vaccines were the ones which have been most widely used in the emergency scheme. 

Under China's emergency scheme, which began in late July, high-risk groups like health care workers, diplomats, etc will receive the vaccines by different firms. These vaccines are yet to be approved by regulators.

The two vaccines CNBG is creating are still in their phase three trials for safety and efficacy in many countries-- the United Arab Emirates, Bahrain, Peru, Morocco, Argentina and Jordan.

The ones who have been administered the vaccine are mostly people who work overseas and as none of them has contracted the virus yet, it proves "the effectiveness of the vaccines," said Zhou.

Currently, eight vaccines are undergoing phase three trials around the world. Of these four are being made by Chinese companies, including the two by CNBG and one by Beijing based medical firm Sinovac. Sinovac’s vaccine, CoronaVac is currently undergoing tests in Brazil and Indonesia, with plans of the trials to take place in more countries. While CNBG’s vaccines have also been offered to employees of some businesses and will be provided to employees of Huawei as per a recent deal between the telecom giant and the pharmaceutical company. 

Three of the four Chinese vaccines have been approved for emergency civilian use and the fourth has been approved for use by the military. The one that the military has greenlighted is a candidate vaccine developed by CanSino and the Academy of Military Medical Sciences.
