Zhang Boli, member of the expert group of the central steering group for epidemic prevention and control, academician of the Chinese Academy of engineering and President of Tianjin University of traditional Chinese medicine, opened the lecture on the evening of the 17th.
Academician Zhang Boli:
even if the epidemic is under control, we still need to wear masks
Academician Zhang Boli said: "from now on, the new crown has no clear relationship with temperature. So the temperature in Indonesia and India is very high, but now it infects a lot. Even if the epidemic is under control, I think it's necessary to wear masks. It's really a habit. I don't think this mask can be taken off in a year, at least by this time next year. We must be prepared for this. "
When can we use the new crown vaccine?
Academician Zhang Boli replied: "China's vaccine development is at the forefront of the world. At present, three vaccines have been approved for clinical use in China. The first step is the RNA vaccine made by academician Chen Wei. The first phase of 108 cases has been evaluated. Now 500 cases in phase II have been enrolled. If this period goes well, she will carry out the third experiment. "
But he said that the key to the next step is production capacity. The vaccine is successful. We have a population of 1.4 billion, and the vaccine with average production capacity can only supply 10 million people. Ten million people are too few, so we will expand our production capacity. The expansion of production capacity is also limited and has a time.
masks are still recommended in three cases
China CDC also gave the latest advice on wearing masks.
At a press conference held by the joint defense and control mechanism of the State Council on the afternoon of May 17, Feng Luzhao, a researcher of China CDC, suggested wearing masks under the following three circumstances:
|1. Masks should be worn in closed public places, such as public transportation, elevators and public places with many people;|
|2. When you are ill, especially if you have fever or cough, wear a mask to avoid infecting others;|
|3. Wear masks in hospitals and other special environments.|
Feng also said that under the condition of good ventilation conditions and being able to maintain a relatively good and safe social distance, people can not wear masks, such as parks, streets with fewer people and playgrounds. Especially when you are exercising hard, you can't wear a mask. In addition, masks are not required in low-risk areas where no new cases have been reported in the near future.
