In addition to Hubei, many places in the country have also begun to be vaccinated.
In Anhui, on October 9, Wuhu released an official WeChat public account to release a message that on October 8, Nanling County, Wuhu City, has begun to strengthen the injection of the new crown vaccine. Previously, Wuhu counties (cities) have also successively launched to strengthen vaccination, such as Jinghu District, Yijiang District, Wanlan District, and Fanchang District. Fuyang released a weChat public account to release a message that Fuyang City began to start the new crown virus vaccine to strengthen the injection of immunization work from October 9; according to the news of Dahui News on October 9, the Beacon Hill Community Service Center in Shushan District of Hefei City began to receive the new crown vaccine "reinforcing needle" from the same day, and whether other counties and districts in Hefei have also started to launch "reinforcing injections" still need to wait for the notice issued by the county and district disease control.
In Fujian, according to CCTV News reported on October 9, Jinjiang City, Fujian Province, has officially launched the intensification of immunization of high-risk groups, and carried out a third dose of vaccination for key groups with the second dose for 6 months. From 10 October, Xiamen Will also initiate enhanced immunization for people over the age of 12 who have completed two doses of inactivated vaccine or one dose of adenovirus vector vaccination for 6 months.
In Heilongjiang, according to the Suihua Evening News on October 9, on October 7, the Suihua City Headquarters for Responding to the Novel Coronavirus Pneumonia Epidemic issued the "Suihua City New Coronavirus Vaccine Enhanced Immunization Implementation Plan", and officially launched the new coronavirus vaccine enhancement immunization work from now on.
In Hainan, according to the South China Sea Network, from October 4, 2021, the new crown virus vaccine for key populations will be launched to strengthen immunization.
In Zhejiang, on September 17, the 77th press conference on the prevention and control of the new crown pneumonia epidemic in Zhejiang Province announced that the work of strengthening the immunization of key populations will be carried out in an orderly manner in accordance with the unified arrangements of the state in the near future.
In Henan, as early as September 16, Henan Daily reported that the state is about to launch the new crown virus vaccine to strengthen immunization, and Henan will do a good job in the calculation of target groups, cost protection and other preparations as soon as possible to ensure the smooth development of key populations to strengthen immunization.
At present, the vaccines that have been approved for vaccination in China involve three technical routes of inactivation, adenovirus vectors, and recombinant subunit new crown vaccines, and the manufacturers include Sinopharm Group China Biologics, Kexing, CanSino Biologics, Zhifei Biologics and other enterprises.
1. What is enhanced immunization?
Boosting immunization refers to the number of vaccine doses that, after completing vaccination, are supplemented according to the situation of antibody regression to maintain the body's immunity to the virus. For example, at this stage, the new crown virus inactivated vaccine is fully vaccinated with 2 injections, and according to the degree of decline in the level of antibodies in the human body, 1 injection is carried out, which is called strengthening immunization.
Second, why should we carry out immunization strengthening?
At present, the global new crown pneumonia epidemic is still developing continuously, the new crown virus is accelerating the spread of mutations, and the risk of the epidemic entering China is still high. Recently, the local cluster epidemic caused by overseas imports in many places fully shows that China's "external prevention of imports, internal prevention of rebound" is still facing greater pressure.
As of the end of September, the total number of doses of the new crown virus vaccine worldwide has exceeded 6 billion doses, China has exceeded 2.2 billion doses, and nearly 1.05 billion people across the country have completed the whole process of vaccination.
According to the results of domestic and foreign studies, the new crown vaccine has played a great role in preventing infection and reducing the incidence of disease. However, after vaccination, after a period of time, some people's immunity is declining, and the protective effect is weakening.
In response to this problem, the relevant experts of the national vaccine research and development special class organized the demonstration, and the relevant enterprises also reported the research results of strengthening the clinical trial after immunization. The results of the study showed that no serious adverse reactions occurred to boost immunity, and the neutralizing antibodies grew rapidly or rebounded.
In the face of the ongoing pressure to prevent and control the new crown epidemic, vaccines will play a key role. Strengthening immunization is of great significance for protecting susceptible populations and effectively curbing the spread of the epidemic.
In addition, the antibody that strengthens immune production has stronger staying power. Six months after boosting immunization, although antibody levels also declined, they were still higher than the peak after two or one doses. These suggest that there will be a better protective effect after strengthening immunity.
Strengthening immunity can better cope with mutant strains. There are relevant studies on inactivated vaccines to enhance immunity, and after the study, it has also been seen that not only the antibody level has increased, but the antibody spectrum has also been wider, which means that it will have a better protective effect on the mutant strain.
Is it safe to strengthen immunization?
Experts from the National Vaccine R&D Special Class have conducted sufficient research and demonstration, and there are no serious adverse reactions to strengthen immunization, and neutralizing antibodies will grow rapidly.
Which populations give priority to strengthening immunization?
According to the needs of epidemic prevention and control, people aged 18 and above who have been vaccinated with 2 doses of COVID-19 inactivated vaccine for 6 months can be upgraded in Yichang.
Priority will be given to strengthening immunization among people at high risk of COVID-19 infection and in key positions to ensure the basic operation of society. People at high risk of COVID-19 infection, including people with a high risk of occupational exposure, front-line customs inspection and quarantine personnel at ports involved in imported cold chain goods, relevant personnel such as loading, unloading, handling and transportation at ports, international and domestic transportation practitioners, border port staff facing a high risk of overseas epidemics, medical and health personnel, etc., and people with a risk of infection abroad, such as those who work and study abroad for business and private reasons.
V. How long is the interval to strengthen immunity?
The interval between booster immunization and full immunization is at least 6 months. That is, it takes at least 6 months after full immunization before the booster dose can be administered.
For example, if immunization is strengthened with an inactivated vaccine, it is given at least 6 months apart at least after the second dose.
Sixth, how to choose a vaccine to strengthen immunization
In the selection of vaccines, the current recommendation of national experts is to use already vaccinated vaccines for enhanced immunization. In principle, people who have completed 2 doses of vaccination using the same inactivated vaccine should in principle use the original inactivated vaccine for 1 dose booster; for people who have completed 2 doses of vaccination with different inactivated vaccines, in principle, priority will be given to using the same vaccine as the second dose of inactivated vaccine for 1 dose booster, and if the second dose of the same vaccine cannot continue to be supplied, the same vaccine as the first dose of inactivated vaccine can be used for 1 dose of enhanced immunization.
In simple terms, in principle, the vaccine produced by the original vaccination enterprise is used, and if the same enterprise cannot meet the supply, it is also necessary to choose the same technical route of the vaccine for vaccination. For example, if you have received two doses of inactivated vaccine before, you should also receive inactivated vaccine when strengthening immunization.
VII. How to organize the implementation of immunization enhancement?
(1) For people with high occupational risk, the unit or industry is the main organization of collective vaccination, and each unit and the previous vaccination point joint system are vaccinated. Priority will be given to vaccinate people at high risk of COVID-19 infection and key positions to ensure the basic operation of society.
(2) Other groups of people, go to the new crown virus vaccination site for vaccination. The list of COVID-19 vaccination sites currently available in Yichang City is as follows:

VIII. Principles of Vaccination
Informed consent, voluntary free of charge.
IX. What are the precautions for strengthening immunization?
Bring your previous vaccination voucher and ID card before vaccination.
Contraindications are strictly avoided, and if an allergic reaction occurs before receiving the new crown virus vaccine, whether it is the first or second dose, the booster injection can no longer be given after being contraindicated.
After inoculation, it is also necessary to stay on site for at least 30 minutes. A small number of people will have a slight general reaction, such as tenderness at the vaccination site, fever, headache, and body aches, which generally do not need to go to the hospital, and pay attention to rest in 1-2 days will generally relieve themselves. However, if the symptoms are felt to be severe and last for a long time, it is recommended that the recipient go to the hospital for diagnosis and treatment in time.
The epidemic is not over, and the epidemic prevention must not be relaxed
