When the "flu" meets the "new crown", is the "vaccine" ready?

　　Under the new crown pneumonia epidemic, this year's flu season has attracted much attention.

Statistics released by the World Health Organization on September 14 show that there are more than 28.87 million confirmed cases of new coronary pneumonia worldwide.

How about the development, production and vaccination of China's new crown vaccine?

How will international cooperation be carried out?

　　"News 1+1" connects with Wu Guizhen, chief expert of biosafety at the Chinese Center for Disease Control and Prevention, and pays close attention to:

How is the current progress of China's new coronavirus vaccine?

Wu Guizhen, chief biosafety expert of the Chinese Center for Disease Control and Prevention:

I am participating in the safety review of vaccine production workshops in Wuhan. At present, China's vaccine research and development and production are at the forefront of the world.

At present, there are 9 vaccines in the world that have entered phase III clinical trials, and China accounted for 5 (a new coronavirus vaccine that China has international cooperation with other countries has just entered), so it is very fast.

The new coronavirus is a high-risk virus and needs to be produced in a negative pressure workshop.

Experts from the Health Commission are now intensively reviewing the production workshops. Two production workshops have passed the examination and approval, and the third is in progress.

Why was the flu vaccination guide issued earlier this year?

Wu Guizhen, chief expert on biosafety at the Chinese Center for Disease Control and Prevention:

Respiratory infectious diseases, such as influenza and pneumonia, are prone to high incidence in autumn and winter, and low temperature is easy to spread for the new

.

There are similarities between the early symptoms of the new crown and the flu. One is the season, and the symptoms are similar. Therefore, we hope that everyone can get the flu vaccine to prevent the occurrence (infection) from being clinically easy to have some difficulties in identifying.

Is this year's flu vaccine enough for more people to get it?

Wu Guizhen, Chief Expert of Biosecurity at the Chinese Center for Disease Control and Prevention:

Under normal circumstances, influenza vaccines are very important to prevent influenza. Vaccines are the most beneficial, cheapest and most effective means of preventing infectious diseases.

Vaccines are divided into two categories, the national planned immunization vaccine and the second-class vaccine, and the influenza vaccine belongs to the second-class vaccine.

Nevertheless, the country is actively organizing enterprises to produce influenza vaccines.

I think it should be enough, no problem.

Which flu vaccine is recommended this year?

Wu Guizhen, chief expert on biosafety of the National Centers for Disease Control and Prevention:

Every year the World Health Organization organizes vaccine recommendation meetings in February and September, and this year is the same.

From 2020 to 2021, the WHO has also recommended four-component vaccines to us. At present, everyone used this year within the recommended range of the World Health Organization.

Research and cooperation on the new crown vaccine

　　According to information from the WHO, currently, more than 30 new coronavirus vaccines have entered clinical trials globally, and 9 have entered phase III clinical trials, and China accounts for 4 of them.

Data shows that the safety and effectiveness of these four vaccines are currently relatively optimistic, and my country has officially launched the emergency use of the new crown vaccine on July 22.

For the global epidemic, epidemic cooperation is particularly important. On September 11, the United Nations passed the resolution on the new crown pneumonia epidemic, and the key word in it was "cooperation."

How long can ordinary people get the new crown vaccine?

Wu Guizhen, chief expert on biosafety at the Chinese Center for Disease Control and Prevention:

This time will be very short, about November or December, ordinary people can get the new crown vaccine, because according to its Phase III clinical results, the current progress is very smooth.

In April of this year, I was vaccinated as an experimental group. In the past few months, I felt very good. There was no difference. When I was vaccinated, there was no local pain.

How long will the new crown vaccine be effective after vaccination?

Wu Guizhen, chief biosafety expert of the Chinese Center for Disease Control and Prevention:

Because the occurrence of new coronary pneumonia is not long, the time for vaccine development is not long.

Based on past experience and the results of past research, we expect to be effective for about 1 to 3 years.

Because the time is short, we continue to observe.
