Millions of people in China have been given two experimental corona virus vaccines and so far no cases or side effects of code 19 have been reported.
Zhao Song of China National Biotech Group (CNBG), China’s state-owned vaccine company, told China National Radio that millions of citizens have so far received the company’s two experimental vaccines, which are currently undergoing the third phase of clinical trials. ۔
“No one using the vaccine showed any side effects and no one was infected with the code,” he said.
The development comes as the UK’s Oxford University vaccine trial has been suspended due to confirmation of side effects in a volunteer.
The vaccine is currently in the final stages of a trial and was expected to be introduced soon.
Zheng Zhongai, head of China’s National Health Commission (NHC), said in August that since July, key workers have been receiving the experimental corona virus vaccine for about a month to protect them from code 19.
He did not say how many people had been vaccinated or which vaccine was being used, but said medical staff and border officials had been vaccinated.
But now it can be speculated that it may be one of the two experimental vaccines for CNBG.
The vaccine is also being used by China for business people who travel to countries most affected by the corona virus in August.
It is to be noted that 8 corona vaccines are being worked on in China out of which 4 have entered the final stage of clinical trials, out of which 3 are likely to be approved for emergency civilian use.
One vaccine will be allocated to the military.
Zhao Song told China Radio that the vaccine could protect a person from the corona virus for up to three years.
“The results of animal experiments and other research indicate that vaccine protection can last from one to three years,” he said.
“We continued to monitor the initial 180 volunteers who had been vaccinated five months ago and the levels of antibodies to the corona virus were still detected at a stable level and there were no signs of a decrease,” he added. ‘
He said the vaccine would be effective against all types of viruses.
“There has been no fundamental change in the central gene sequence and protein levels of code 19 and changes in the virus in the coming years will not affect the effectiveness of the vaccine,” he said.
In August, China said that vaccines for the prevention of code 19 would be approved only if their efficacy rate was at least 50 percent and their resistance to the corona virus was maintained for six months. Will
A draft proposed by China’s Center for Drug Evolution (CCDE) has come out with regulations regarding the corona vaccine.
According to the draft, there is a minimum efficacy rate for vaccines for emergency use and this will include vaccines that have not completed a clinical trial but will be approved for use based on their efficacy.
Chinese guidelines on vaccine efficacy follow guidelines from the World Health Organization and the US Food and Drug Administration.
The guidelines come as 4 corona vaccines have entered the final stages of clinical trials in China.
