The mutation of the new crown virus has updated the previous concept of prevention and control, and many schools have strengthened prevention and control management after the opening of the school, including the injection of the new crown vaccine. How old are the children of the CORONAVIRUS vaccine?
In the beginning of the school season, Professor Liang Zong'an, executive deputy leader of the Sichuan Provincial COVID-19 Medical Treatment Expert Group and director of the Department of Respiratory and Critical Care Medicine of West China Hospital of Sichuan University, gave an important lesson to the teachers and students of Dujiangyan in Chengdu. At the invitation of the Publicity Department of Chengdu Dujiangyan Municipal Party Committee, Dujiangyan Cd-operative Center, and the expert team of Shoujia Hospital, the first 5G platform hospital in Dujiangyan, Professor Liang Zongan gave guidance at Dujiangyan Shoujia Hospital, participated in the salon activity of "Opening Season, Prevention and Control of Mutation of The New Coronavirus", and carried out free consultations for patients at Dujiangyan Shoujia Hospital.
At the salon site, the heads of Schools such as Dujiangyan Campus of Sichuan Agricultural University, Chengdu Neusoft College, and Guanzhou Primary School consulted Professor Liang Zongan about the details of school prevention and control, focusing on how old the new crown virus vaccine is suitable for children and what are the contraindications of the vaccine.
First, how old are the children of the new crown virus vaccine?
Professor Liang Zongan introduced that now our vaccine is mainly suitable for adolescents aged 12-17 years, and their clinical research has been completed for adolescents of this age. Judging from the completed results, in fact, there are not many adverse reactions to the inactivated vaccine for this part of the population, or most of them have no adverse reactions, indicating that it is very safe for adolescents to be vaccinated. Children under the age of 12 have not been vaccinated because our clinical studies have not yet been completed. Our country's vaccination is strictly in accordance with the completion of phase III clinical procedures before it is widely vaccinated.
Second, why is there still a "breakthrough infection" after vaccination?
Liang Zongan introduced that "breakthrough infection" means that people are still infected after vaccination. Specifically, it should not have been infected after vaccination, but now it is still infected, and this patient is called a "breakthrough infection" case. Although the effectiveness of the new crown vaccine has declined in the face of mutated strains, the existing vaccine will not develop severe diseases to protect patients, and the proportion of protecting the lives of patients is still very high, and vaccination is very important.
Third, should adolescents be vaccinated against COVID-19?
Professor Liang Zong'an said that the mutant strain of the new crown virus "Delta" has become the main virus strain of the global new crown pandemic, and the strain has the characteristics of fast transmission speed, fast internal replication, and long negative time. Liang Zongan believes that adolescents do need to be vaccinated against the new crown, on the one hand, the vast majority of people in China, including adolescents, do not have immunity to the new crown virus, are susceptible to the new crown virus, and after the onset of infection, some people will develop critical illness and even cause death. Not only that, 12-17-year-old teenagers are mostly school students, and once someone is infected with the new crown virus, it is very easy to cause outbreaks and even epidemics. After vaccination, the vast majority of people can gain immunity, which effectively reduces the risk of morbidity, severe illness and death. On the other hand, children are the key group for the construction of immune barriers, and the vaccination of people under 18 years of age against the new crown virus is an important part of building the immune barrier of the whole population.
Fourth, parents are inevitably worried about the side effects of the new crown vaccine, is it safe for adolescents to receive the new crown vaccine?
Professor Liang Zong'an introduced that because each person has individual characteristics, the reaction is different, but the systemic reaction is very small, and some people may have fever, but it is completely controllable and safe. Vaccination with COVID-19 can help recipients build immunity to COVID-19, so getting covid-19 vaccination does not reduce your child's immunity. The world's authoritative infectious disease journal "Lancet- Infectious Diseases" published online the safety, tolerability and immunogenicity of the inactivated new coronavirus vaccine developed by China's Kexing in healthy children and adolescents aged 3-17 in China.
