New crown vaccine emergency use age expands children can rest assured
Pay attention to the new crown vaccination
On June 6, the relevant person in charge of the vaccine research and development team of the Joint Prevention and Control Mechanism of the State Council said in an interview that the country has approved the emergency use of the new crown vaccine to expand the age range to 3 years and above.
The 3-17-year-old child group has been approved for emergency use, so is the process of vaccinating children with the new crown vaccine different from that of adults?
"Same specification, same dosage, same procedure." Yin Weidong, chairman of Kexing Holding Biotechnology Co., Ltd., responded to the reporter of Science and Technology Daily. The safety of the vaccine is good, and the antibody level is the same as that of adults.
Don't parents worry?
In the past prevention and treatment of infectious diseases, whether it was for polio, measles, Japanese encephalitis and other epidemic diseases, children and young people were the key populations for the construction of the immune barrier.
On the one hand, children’s immune system is immature and vulnerable to infections by viruses and bacteria from outside. On the other hand, nurseries, kindergartens, primary and secondary schools, etc. are all concentrated places and are prone to cluster epidemics.
"When we were young, we were all vaccinated with vaccinia and BCG. We didn't get the disease in our entire life when we grew up. This is the effect of vaccines. Therefore, vaccines are the most effective public health measure." Li Liming, a professor at the School of Public Health of Peking University, said a lot of practice It shows that vaccination is the most effective means of preventing and controlling infectious diseases.
Although the new crown virus is a brand new virus, it is still the most effective way to deal with it.
Li Liming emphasized that the prevention and control of infectious diseases consists of three steps, identifying and discovering the source of infection, cutting off the route of transmission, and protecting susceptible populations. The protection of susceptible populations depends on vaccines.
Why is the 3-17 year old group only approved recently?
According to the data published on the official website of the National Health Commission, as of June 7, 2021, 31 provinces (autonomous regions and municipalities) and the Xinjiang Production and Construction Corps have reported a total of 79.134 million doses of new crown virus vaccine.
Various monitoring data indicate that the vaccines currently on the market in my country and being vaccinated on a large scale are safe.
Since for adults, large-scale vaccination shows that the vaccine is safe and effective, why should the group of children aged 3-17 have to wait and wait until they have recently been approved for emergency use?
The so-called everything is ready, only owes east wind.
The "Dongfeng" here is the data and evidence of clinical trials.
In an earlier interview with a reporter from Science and Technology Daily, Li Liming said that what is currently lacking is the clinical trial evidence of the new crown vaccine for people under 18 years of age. Once there is evidence to show the effectiveness and safety of vaccination for this age group, the entire population of vaccination There should be no problems.
"Whether it is an adult or a child, the principle of the vaccine's immune effect is the same. From the perspective of public health strategies, the immune barrier formed by vaccination is the same for everyone, regardless of whether it is children or adults." Li Liming said.
Now, the "east wind" of clinical trials is coming.
In an interview with CCTV a few days ago, Yin Weidong introduced that SINOVAC started a clinical study on minors in early December last year. The clinical study of hundreds of people showed that the safety of vaccination in the 3-17-year-old group is good, and the level of antibody is good. It's the same as adults.
The safety and effectiveness data have been reported to the Joint Prevention and Control Mechanism of the State Council and the State Drug Administration.
According to laws and regulations, emergency use of new crown vaccine for minors is approved
According to Article 20 of the "Vaccine Management Law", in the event of a particularly major public health emergency or other emergency that seriously threatens public health, the health department of the State Council shall make recommendations for emergency use of vaccines according to the needs of the prevention and control of infectious diseases. The drug supervision and administration department can be used for emergency use within a certain range and time limit after organizing the demonstration and agreeing.
Zheng Zhongwei, director of the Science and Technology Development Center of the National Health Commission and the leader of the vaccine research and development team of the Joint Prevention and Control Mechanism Research Team of the State Council, previously introduced that the emergency use conditions and procedures of the new crown vaccine have been verified by experts for countless times. On June 24 last year, the State Council The "New Coronavirus Vaccine Emergency Use (Trial) Program" was approved.
This time, based on existing clinical evidence, the age range for emergency use of the new crown vaccine approved by my country in accordance with laws and regulations has been expanded to 3 years and above.
"When and how to use the vaccine in the minor age group, the National Health Commission will organize relevant experts to conduct demonstrations based on China's current epidemic needs and population composition, formulate immunization strategies, and promote the use of vaccines in different age groups in an orderly manner. "Yin Weidong said.
