A Chinese expert said today that Chinese citizens could begin to be vaccinated against covid-19 in November or December, as clinical trials run smoothly.
Cited by the official press, the main biosafety adviser of the Center for Disease Control and Prevention in China (CDC), Wu Guizhen, said he believed vaccines against the disease caused by the new coronavirus could have an effect between one and three years.
Five of the nine vaccines that have reached the third phase of clinical trials worldwide are being developed by China.
Wu considered that the Asian country is “leading” this process.
The specialist admitted to having participated in one of the tests carried out in the country: “I was injected with a vaccine in April, I volunteered in the tests. I am feeling well now”, he explained.
Wu said that experts from the National Health Commission are “intensively” reviewing pharmaceutical production projects, and that, for now, two have already received authorization to start producing vaccines.
As it is a “high risk” virus, the specialist stressed that it is essential that vaccines be produced in a negative pressure environment that prevents the pathogen from leaking out or into other rooms.
Beijing approved the emergency use of vaccines for health officials and other sectors in late July.
According to a director of the National Biotechnology Group of China (CNBG), at least two experimental vaccines have already been administered to “hundreds of thousands of Chinese, without having reported any side effects”.
