New crown vaccine has been developed! Subject feedback is good, experts predict: the epidemic will be effectively controlled!

Development phase:

Vaccination of volunteers has been completed.

Zheng Zhongwei, director of the science and technology development center of the National Health Commission and head of the vaccine research and development team of the joint prevention and control mechanism of the State Council, revealed that on July 22, the vaccine had begun to be used urgently. CCTV News reported that China’s biological new crown inactivated vaccine international clinical (phase III) has been vaccinated more than 20000 people, with considerable safety performance, and the effectiveness in further observation, is worth looking forward to.

Because China’s “vaccine management law” stipulates that when there is a particularly major public health event, the vaccine can be used urgently within a certain range and within a certain time limit. The purpose is to establish an immune barrier among medical personnel, epidemic prevention personnel, frontier inspection personnel, basic urban operation personnel and other special groups.

Vaccination cases: the subjects were in good condition without discomfort

Back to reality, how do vaccinated people feel?

A female subject who has participated in the phase III vaccination experiment said that there was no special discomfort in the whole process of the test, except that she had some dry heat in her sleep that night, and it was normal the next day. In fact, the number of employees in the first batch of voluntary vaccination units is not very large, which belongs to the small and medium scale; or because of the cooperative business projects with overseas countries, it is necessary to send personnel to these countries. The woman then added, “blood pressure will be measured before vaccination. There is no special physical examination for the time being. But two kinds of people are definitely not allowed to participate in the vaccination, under the age of 18 and pregnant women

So who needs to be injected first?

The government affairs which are closely related to the people or the service window which has been in contact with the ordinary people in work should be the first. For example, medical staff in hospitals, teachers, customs, security inspection, government, military and police, etc., can obtain immunity, which can largely block the rapid spread of new coronavirus; in addition, it is also convenient for the state to monitor the vaccine effect and possible side effects.

Expert opinion: suppress the peak and achieve results

Wu Zunyou, chief epidemiologist of the Chinese Center for Disease Control and prevention, made a speech on the newly developed new crown vaccine Jin. He mentioned that the persistence of immunity produced by human being infected with different viruses is different. Some will have lifelong protective effect, and some will have very limited immunity.

There is no doubt that the new vaccine has protective effect. However, there is no definite conclusion about the duration of immunity. However, scientists, including doctors in the field of disease transmission, generally believe that the new vaccine developed in China has an effective period of 6-12 months. As long as the vaccine has a protective effect, even for 6-12 months, it is also very important. It can effectively control the epidemic and hold down the epidemic peak. With the new vaccine, we can suppress the peak and keep the number of cases under control, which is particularly helpful for controlling the epidemic situation.
