New crown vaccine emergency use, age-expanding children can rest assured to play

Follow the new crown vaccination

June On the 6th, 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.” Reply by Yin Weidong, Chairman of Kexing Holding Biotechnology Co., Ltd. The reporter of Science and Technology Daily said that early clinical studies of minors showed that children aged 3-17 use the same vaccine as adults, with good safety and the same antibody level as adults.

Do parents need to worry?

In the past prevention and treatment of infectious diseases, whether it was for polio, measles, Japanese encephalitis and other epidemic diseases, children were all Immune barrier to build a key population. On the one hand, because children’s immune system is immature, they are susceptible to infection by viruses and bacteria from outside. Since nurseries, kindergartens, primary and secondary schools, etc. are all concentrated places, clusters of epidemics are prone to occur.

“When we were young, we were vaccinated with Vaccinia and BCG vaccine. When we grow up This is the effect of vaccines for a lifetime. Vaccines are the most effective public health measure.” Li Liming, a professor at the School of Public Health of Peking University, said that a lot of practice has shown 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 the most effective way to deal with it. Li Liming emphasized that the prevention and control of infectious diseases are three links, identifying and discovering the source of infection, cutting off the route of transmission and protecting susceptible population, and protection of susceptible population depends on vaccines.

Why is the 3-17 year old group only recently approved?

According to the data published on the official website of the National Health Commission, as of June 7, 2021, 31 provinces (autonomous regions, municipalities) and the Xinjiang Production and Construction Corps have reported a total of 79.13 million doses of the 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 3-17-year-old child group wait and wait until it has been approved for emergency use recently?

The so-called everything is ready, only owe Dongfeng. The”Dongfeng” here is the data from clinical trials and evidence.

In an earlier interview with a reporter from Science and Technology Daily, Li Liming said that the current lack of clinical trial evidence for the new crown vaccine for people under the age of 18, once there is evidence to show the effectiveness and safety of vaccination for this age group Sex, vaccination and prevention for the entire population should be no problem.

“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 strategy, the immune barrier formed by vaccination is the same for everyone, regardless of whether it is a child or an adult.” Li Liming said .

Now, the”dongfeng” of clinical trials is coming.

In an interview with CCTV a few days ago, Yin Weidong introduced that SINOVAC In early December last year, a clinical study of minors was started. Clinical studies of hundreds of people showed that the safety of vaccination in the 3-17-year-old group is good, and the antibody level is the same as that of 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, the emergency use of the new crown vaccine for minors is approved

According to Article 20 of the Vaccine Management Law, there is a particularly major public health emergency or other serious threat to the public For health emergencies, the health department of the State Council proposes emergency use of vaccines based on the needs of infectious disease prevention and control, and the emergency use of vaccines can be used within a certain range and within a certain period of time after the organization of the State Council’s drug regulatory authority has approved it.

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 demonstrated countless times by experts , The State Council approved the”New Coronavirus Vaccine Emergency Use (Trial) Plan” on June 24 last year.

Based on the 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 will the vaccine be used in the minor age group and how to use it, the National Health Commission will organize relevant experts according to China now needs to demonstrate the epidemic situation with the composition of the population, formulate immunization strategies, and promote the use of vaccines in different age groups in an orderly manner.” Yin Weidong said.
