Zeng Yixin, deputy director of the National Health Commission, introduced that relevant departments are strengthening guidance, coordinating vaccine research and development, and manufacturing companies are actively increasing production and capacity, while meeting domestic needs, while taking into account international needs
.

At present, 21 new coronavirus vaccines in China have entered the clinical trial stage.
Among them, 4 vaccines have been approved for conditional marketing in China, 6 vaccines have been approved for emergency use in China, and 8 vaccines have been approved for phase III clinical trials abroad.
, 3 vaccines were approved for phase I clinical trials in developed countries

As of June 5, we have inoculated about 700 million by ourselves and exported about 350 million, so we can see from this data.
When we came out, we actually took into account domestic needs and international needs

National Health Commission: Pay close attention to issues such as virus mutation and vaccine protection timeliness

Zeng Yixin said that relevant departments have been paying close attention to issues such as the mutation of the new coronavirus and the timeliness of vaccine protection.
Once the mutation of the virus exceeds the scope of prevention and control of the existing vaccine, the vaccine will be upgraded
.

Zeng Yixin, deputy director of the National Health Commission: At present, although this virus is constantly mutating, it is still within the scope of our vaccine prevention and control.
Please rest assured
.
However, we cannot take this issue lightly.

We must continue to observe the mutation of the virus and closely monitor the mutation of the virus.

Zeng Yixin explained the question of how long the protection period of the new crown vaccine is of concern to everyone
.

Zeng Yixin, deputy director of the National Health Commission: According to many media outlets, the antibody will come down within six months after the vaccine.
Is there any protective effect? Here I want to explain to everyone that the protective effect of vaccines does not rely solely on antibodies
.
Vaccines enter the immune system to produce antibodies.

This antibody does continue to decline for a period of time, but our immune protection mainly relies on immune memory, which means that the immune system remembers the virus
