China's disease control expert: my country may need 1 billion people to be vaccinated to build an immune barrier

my country is currently accelerating the new crown vaccination in key regions, key populations, and key cities in accordance with the sequence of steps.

As of 24:00 on April 10, a total of 164.

In response to the situation regarding the prevention and control of the new crown epidemic and vaccination, "Face to Face" interviewed Wang Huaqing, chief expert of the China Center for Disease Control and Prevention's immunization program.

For the first time in the history of human vaccination

The largest national daily newspaper system

From March 24, China has launched a daily reporting system for COVID-19 vaccination data.

Reporter: According to our vaccination setup and plan, what is the current vaccination situation at what time node?

Wang Huaqing: If our country wants to build an immune barrier, it may require more than 1 billion people to be vaccinated against the new crown vaccine.

How safe is the new crown vaccine?

Although in the past week, the number of domestic new crown vaccines has increased rapidly from three to four million to 7 million in a single day, but compared with some countries with an inoculation rate of 40% or even 60%, it is still relatively low.

Reporter: The new crown vaccine is completed at a very fast speed from research and development to production and application.

Wang Huaqing: The research and development of the new crown vaccine has gone through pre-clinical and clinical phases 1, 2, and 3 before it is marketed.

Reporter: Is the safety performance of this vaccine developed beyond normal rules 100% safe?

Wang Huaqing: Any vaccine has its risks.

Do I need to wait for the new crown vaccine?

There are still people in China who are holding a wait-and-see attitude towards the vaccine, entangled in whether it is necessary to fight or question whether it can be used, at least 70 countries and regions around the world have approved the use or agreed to purchase the Chinese vaccine, and many foreign leaders have been vaccinated early.

However, due to the strong domestic epidemic control, some people are still waiting and watching and expect a better vaccine to appear.

Reporter: Everyone thinks that since we may do better in the future, and the current situation is not so urgent, can I postpone the vaccine for a while, which might be better for me personally?

Wang Huaqing: Everyone delays this vaccination, then our immune barrier will never be established.

Reporter: But many people will also say why I should rush ahead?

Wang Huaqing: There is still a problem.

After being vaccinated, we have immunity, we can no longer serve as a source of infection, and the virus can no longer spread.

Can the new crown vaccine deal with virus mutation?

The new crown epidemic was declared by the World Health Organization as "the most serious global public health emergency in history", and the new crown virus that caused the epidemic is called by experts as the most cunning virus known to mankind.

Reporter: You just talked about the possibility of virus mutation.

Wang Huaqing: Although we have seen the mutation of the virus, it seems that vaccination is still useful at present.

In view of the virus mutation, scientists from various countries are currently trying to monitor the mutation, and find corresponding solutions for those that may affect the effect of the vaccine.

Why is it still diagnosed after vaccination?

On March 18, a doctor in Xi'an City was diagnosed with a case of new coronary pneumonia after having already completed two injections of the new crown vaccine.

In this regard, Wang Huaqing said that the best effect of the vaccine is to prevent infection.
The new crown vaccine has the effect of preventing infection and disease, and the effect of preventing severe illness is higher.

Wang Huaqing: None of the vaccines currently on the market have a protection rate of 100%.
They may fail due to individual reasons or vaccine characteristics.
It is not universal.

This situation can be explained based on the current protection efficiency.
According to the results of the current Phase III clinical trials, including the recent post-marketing protection effects published abroad, the vaccine actually has a protective effect on most people.

Can pregnant women get the new crown vaccine?

With the deepening of the new crown vaccination, some of the original restrictions have also changed.

Just last month, Shanghai and Beijing organized successively to vaccinate the new crown vaccine for elderly people 60 years of age and older who have a need for vaccination and have a good physical condition.
In the early stage of vaccination, elderly people over 60 are not recommended to be vaccinated.

Reporter: Pregnant women are a very special group.
Can pregnant women receive the new crown vaccine now?

Wang Huaqing: The suggestion we give now is that pregnant women (temporarily) should not be vaccinated.

Reporter: What should I do if I get pregnant by accident after being vaccinated with the new crown vaccine?

Wang Huaqing: In this case, we have also given corresponding suggestions in the guide.
After the vaccination, you do not need to take special measures.
Follow-up health care during pregnancy and follow-up work are the same as other people’s measures.

Which one of the five new crown vaccines should be used?

In terms of the development of new crown vaccines, China has always been the world's first phalanx.

At present, the new coronavirus vaccines of five manufacturing companies in my country have been approved for conditional marketing or emergency use, and all of them are vaccinated free of charge for citizens.

Which vaccine should you choose to vaccinate yourself is also a question that many people are struggling with.

Wang Huaqing: The reason why the new crown vaccine can be approved for marketing and use actually meets the most basic requirements.
In this case, it is up to the state to determine which places to supply which vaccines and uniformly deploy them.

We hope to vaccinate as soon as possible, establish an immune barrier as soon as possible, and try not to consider individual differences, because if there is a big difference, there must be a way.
