Chen Wei revealed: China's first single-shot vaccination of the new crown vaccine effect

my country's first adenovirus vector new crown vaccine was approved for conditional marketing on the 25th.

On the 25th, the new crown vaccine developed by Chen Wei's team was approved for conditional listing.

The annual production capacity of a single injection of new crown vaccine may reach 500 million.

Chen Wei: What we do is genetically engineered vaccines.

Current observational data show that the severe protection rate of the adenovirus vector new crown vaccine has reached more than 90%.

Chen Wei: Vaccines are the most critical data, so looking at your data on the critical illness protection rate, this is the first point to pay attention to.

So far, the people we have vaccinated include people in an extreme environment.

Chen Wei: So far, the people we have vaccinated include people in an extreme environment.

Six months after the injection of a vaccine, another injection of the enhanced version can increase the immune response by 10 times or 20 times.

Chen Wei: The data for the 6 months so far is available.

On April 12 last year, the age limit was lifted in the second phase of clinical trials in Wuhan.

Q: Is it possible for the vaccine developed by Chen Wei's team to spread to the entire population faster?

Chen Wei: Actually, when we were in the world's first Phase II clinical trial on April 12, 2020, we released the upper limit of age.

There is no doubt that China's vaccine research and development ranks first in the world.

Q: From the perspective of the world, what is the level of vaccine research and development that we have reached now?

Chen Wei: The first phalanx, undoubtedly, this is something that few countries can do.
Therefore, I said just now that we are neither arrogant nor self-defeating.
We should learn from others' strengths and make better and safer vaccines.
However, we must have confidence in this process.
