Chinese nationals could start vaccinating against COVID-19 in November or December as clinical tests are done without backlash, an expert from the Center for Control and Prevention of Diseases of China (CDC) said quoted in the official press today.
The CDC’s chief biosafety advisor, Wu Guizhen, expressed her belief that vaccines against the disease caused by the SARS-CoV-2 coronavirus could work between one and three years, the state-run newspaper Global Times said.
Currently, five of the nine vaccines that have reached the third phase of clinical trials worldwide are being developed by China. Wu said that it is the Asian country that is “leading” the race to discover it.
In fact, the expert took part in one of the studies carried out in the country: “In April I was injected with a vaccine and I volunteered for the tests. I’m fine now, ”she explained.
With regard to the manufacture of the vaccines, Wu announced that experts from the National Health Commission are “intensively” examining the production facilities and that two have already received the green light from the authorities.
As it is a “high risk” virus, the expert points out that it is essential that the vaccines are manufactured in a negative pressure environment that prevents the pathogen from being filtered outside or into other rooms.
Beijing approved the emergency use of the vaccines for healthcare and other sectors in late July, so the general population would not be the first to receive the injection in November when that date is finalized.
As stated a week ago by a director of the China National Biotechnology Group (CNBG), developer of two of the Chinese immune sera that are in phase three of the clinical trials, at least two experimental vaccines have already been administered to “hundreds of thousands” by Chinese ” without contagion or side effects.
So far, human clinical trials have begun with nearly 40 possible vaccines around the world, a dozen of which are being conducted in China.
