What happened to the “full moon” vaccination for the key population of novel coronavirus vaccine?

.

Mr

.

Zhang, who lives in Beijing, received his first dose of the vaccine this week

.

He told reporters that there was no abnormal feeling after vaccination, but there was some muscle ache at the needle mouth

.

In about two weeks, he will receive a second dose of the vaccine

.

Since last December 15th, China novel coronavirus pneumonia vaccine has been vaccinated by the focus population

.

Feng Duojia, President of China Vaccine Industry Association, said in an interview with reporters on January 16 that from the relevant data, the vaccination progress is normal at present

.

Shanxi is carrying out the vaccination work for the key population aged between 18 and 59

.

According to Wei Liang, the new vaccine currently being used in China is inactivated vaccine

.

Feng Duojia said that the technology of this kind of vaccine has been recognized all over the world

.

It has been used for decades and has been used by billions of people

.

It is a well tested and reassuring vaccine

.

“From the actual combat experience, the inactivated vaccine is stable and reliable.” On January 13, Yin Weidong, chairman of Beijing Kexing Zhongwei Biological Technology Co., Ltd., said that as of January 10, the company had provided more than 7 million doses of novel coronavirus inactivated vaccine kelefu to all provinces, autonomous regions and municipalities in China for emergency use

.

Yang Xiaoming, chairman of Sinopharm China biology, also said in an interview with Chinese media on the 15th that since the start of vaccination for key groups, more than 10 million inoculations have been given nationwide

.

The vaccination was divided into two injections with an interval of two weeks

.

Wei Liang photographed Duojia and said that the relevant data should be inferred by the enterprises according to the vaccine supply

.

According to the relevant vaccine delivery plan, this progress belongs to the normal speed

.

“First of all, we need to consider the population coverage in order to achieve the population immune barrier, and also consider the limited number of vaccines.” China’s novel coronavirus vaccination is implemented according to the “three-step” strategy

.

The first step is to vaccinate the key population with high risk of infection, including the staff engaged in import cold chain, port quarantine, ship pilotage, air service, fresh food market, public transport, medical and disease control, as well as the staff going to work and study in medium and high risk countries or regions

.

The second step is to vaccinate high-risk groups, that is, those who are prone to severe illness or even death after infection with new coronavirus

.

The third step is to vaccinate the general population

.

Why such a strategy? “Because the number of vaccines is limited, it needs to be divided according to the risk of infection.” Feng Duojia said that this is also in line with the basic guidelines of the World Health Organization for vaccination in various countries

.

The reason why the current vaccination population in China is controlled between 18 and 59 years old is that the experimental data of this age group has been obtained, and the experimental data of “one old and one small” age groups of 60 years old and under 18 years old are still under study

.

Each recipient should fill in the informed consent form before vaccination

.

Photo by Wei Liang, Yang Xiaoming also revealed that according to the data obtained and the application procedures of the State Food and drug administration, people aged 3 to 17 are expected to be granted the novel coronavirus vaccine before March this year

.

Feng Duojia said that this shows that the trial of the relevant age groups has been completed

.

However, he pointed out that vaccination can cover all ages, and the follow-up work depends on whether the quantity of vaccine can keep up with the supply

.

There must be priorities in the specific vaccination process

.

“In theory, it’s all about vaccination, but step by step.” In fact, Yang Xiaoming also mentioned in the interview that, from the point of view of “receiving as much as possible”, vaccines are “still in short supply”

.

“The world is in short supply.” Feng Duojia said that most of the figures reported now are production capacity rather than output

.

There is a time limit to the production capacity

.

For example, the production capacity of a vaccine company can reach 1 billion units, but it may take two to three years to reach this capacity

.

Detailed figures should focus on the production per unit time

.

He also said that active prevention of new coronavirus, vaccination is currently the only effective way

.

Novel coronavirus pneumonia may be developed in the future, but it still takes time

.

On January 14, doctors and nurses vaccinated taxi drivers with the new vaccine at the vaccination site of Guangzhou Red Cross Hospital in Guangdong Province

.

At present, Guangdong Province is promoting the vaccination work of novel coronavirus vaccine in an orderly way according to the priority port cities and priority key groups

.

According to Li canon, although experts at home and abroad have called for “taking it as much as possible”, some people still say they are not willing to get the novel coronavirus vaccine or hold a wait-and-see attitude

.

“It’s because we don’t know about vaccines,” Feng said The probability of side effects of vaccination is very small

.

Even if there is a little adverse reaction, it is nothing compared with the pain of illness

.

“Our advice to you now is that if you have the chance to get vaccinated and there are no contraindications, you should take it as soon as possible, and don’t hesitate to worry about other problems with the vaccine.” Is it necessary for all people to be vaccinated with the new vaccine to construct the population immune barrier? Feng Duojia said that it is not necessary

.

The country is working out more detailed immunization program, and the vaccine coverage rate of different diseases is also different

.

The vaccine is not 100% effective

.

The “discounted” part should be converted into the number of people who need to be vaccinated

.

On January 8, the medical staff of Xinjiekou community health service center, the first cultural center of Xicheng, Beijing, inquired and registered the vaccinators

.

Starting from January 2021, each district of Beijing will carry out the work of new coronavirus vaccination batch by batch according to the national key vaccination population

.

Tian Yuhao, consultant of who vaccine R & D Committee and researcher of CDC Shao Yiming, also said in an interview earlier this month that the protection rate of vaccine is not 100%

.

For example, the protection rate of the first vaccine approved by China is about 80%

.

More people need to be vaccinated if 66% of the population immune barrier is to be established

.

“We calculated that about 85% of the population would be vaccinated.” Feng Duojia believes that 85% is a theoretical figure, and the specific vaccination rate depends on the change of the epidemic situation

.

Vaccination also interferes with the epidemic situation

.

After a certain stage, the epidemic trend will change

.

In such a dynamic process, vaccination work should be adjusted accordingly

.

If China’s novel coronavirus pneumonia is no longer more prevalent, the 85% coverage rate may be the same
