Visit the scene
Bus mobile vaccination
"You take your ID card here to line up for registration..."
"The interval between the strengthening needle and the second needle needs to be more than 6 months..."
A few days ago, on the square in front of Tianshuiyuan Street Book Wholesale Market in Chaoyang District, Beijing, two mobile vaccination buses with eye-catching colors parked here.
Under the guidance of the staff, the people vaccinated on the spot lined up in an orderly manner according to the one-meter noodles, scanned the code, measured the temperature, and confirmed that there was no contraindication to vaccination, signed the informed consent form, filled out the vaccination form, and then vaccinated in the first mobile vaccination.

Entering the mobile vaccination vehicle, the medical staff are working according to their respective responsibilities, assisting the affected residents to complete the vaccination in turn.
There are two vaccination stations in the vaccination vehicle. In order to deal with special situations, the vehicle is also equipped with an emergency treatment area, equipped with blood pressure meters, emergency medicines, etc.

In the whole country, there are many other people like Liulitun Sub-district who promote the intensive immunization work of the new crown vaccine.
Authoritative answer
Boost immune antibody
Why do we need to carry out the new crown vaccine booster immunization?
Can the booster cope with the constantly mutating virus strains?
How long is the interval between the new crown vaccine booster vaccination and the full vaccination?
"According to the results of domestic and foreign research, after the application of the new crown vaccine, the antibody level has declined over time. Intensified injections can quickly increase the antibody level by increasing the number of doses of vaccination." Chief of Immunization Program, China Centers for Disease Control and Prevention Expert Wang Huaqing said at a press conference on the Joint Prevention and Control Mechanism of the State Council that the current research shows that some inactivated vaccines after the third shot are compared with one month after the second shot. The antibody level is probably increased by about 5 times, and some may be higher, which means that it will produce a better protective effect.
Regarding the problem of virus mutation, Wang Huaqing said that all current vaccines still have a protective effect on the disease caused by the mutant strain in the early stage, especially the protective effect on severe illness is more obvious.
"Currently, the interval between the intensified injections for more than 6 months is determined based on some results of pre-clinical studies and expert argumentation." Wang Huaqing said that based on past experience with other vaccines, if the interval is increased, the overall immune effect will not be improved. Will be affected too much.
However, if the interval is longer, as the antibody level decreases, once the source of infection is exposed, the risk of infection will increase. Therefore, it is recommended that everyone follow the interval requirements and carry out enhanced immunization work as soon as possible.
The National Health Commission recently released the new crown vaccine booster immunization related questions and answers (hereinafter referred to as "Q&A"), showing that the current vaccines that can be used to implement booster immunization include Sinopharm Zhongsheng Beijing Company, Beijing Kexing Company, and Sinopharm Zhongsheng Wuhan Company. Inactivated vaccines and adenovirus vector vaccines of Tianjin Cansino Company.
According to the needs of epidemic prevention and control, booster immunizations will be implemented for people aged 18 and over who have received the above-mentioned vaccines for 6 months.
How to determine the type of booster vaccination against the new crown vaccine?
Questions and answers remind that at this stage, the original vaccine that has been vaccinated should be used for booster immunization.
Among them, people who use the same new coronavirus inactivated vaccine to complete two doses of vaccination, in principle, use the original inactivated vaccine for one dose booster immunization; people who use different inactivated vaccines to complete two doses of vaccination are given priority in principle. The same vaccine as the second dose of inactivated vaccine is boosted once. In the event that the same vaccine cannot be supplied in the second dose, the same vaccine as the first dose of inactivated vaccine can be used for one booster immunization. ; People who are vaccinated with adenovirus vectors are boosted with the original vaccine.
Regarding where to get the booster shots, the Q&A pointed out that, in principle, the booster immunizations for high-risk groups and key positions that guarantee the basic operation of the society are organized and implemented by relevant units; other groups can go to the designated vaccination unit in the jurisdiction for appointment vaccination.
For specific vaccination information in each region, please refer to the official information issued by the local health department or the CDC.
Important reminder
Don't relax in flu prevention and control
At a press conference on the Joint Prevention and Control Mechanism of the State Council held a few days ago, Wu Liangyou, deputy director of the CDC of the National Health Commission, introduced that the overall epidemic situation across the country has stabilized, and the epidemics in many provinces affected by the epidemic in the early stage have been effectively controlled. Successfully blocked the spread of the virus.
The epidemics in Heihe in Heilongjiang, Shijiazhuang in Hebei, Zhengzhou in Henan, and Chengdu in Sichuan are gradually being brought under control.
The epidemic situation in some areas such as Dalian in Liaoning, Beijing, Shangrao in Jiangxi, and Dehong in Yunnan still needs attention.
Monitoring results show that since March, the country's influenza activity has been higher than the level of the same period last year.
Especially since September, the influenza activity level in some southern provinces has shown an obvious upward trend.
Experts comprehensively judged that with the advent of winter and lower temperatures, the risk of a superimposed epidemic of respiratory infectious diseases such as the new crown pneumonia epidemic and influenza has increased.
"The role of the new crown vaccine has been well reflected in the process of preventing the new crown, and the flu vaccine is the most effective means of preventing influenza, especially for infants and the elderly after vaccination can reduce the risk of serious complications." Wang Huaqing pointed out that vaccination The new crown vaccine cannot replace the flu vaccine.
The technical guidelines for influenza vaccination in China have identified the priority groups for influenza vaccination. The elderly and children are the key groups for influenza prevention and control.
In the "New Coronavirus Vaccination Technical Guidelines (First Edition)", it is currently recommended that the interval between influenza vaccine and new coronavirus vaccination be at least 14 days.
"In addition to paying attention to the time interval during vaccination, the following points should also be paid attention to." Wang Huaqing emphasized that in the past vaccination with influenza vaccine, especially the vaccine with the same technical route, if there is an acute allergic reaction, the follow-up influenza vaccination should not be vaccinated; During the process, the recipient should truthfully report his health status and medication history to the vaccination doctor. It is currently seen that some drugs will affect the effect of influenza vaccination; currently there are two main types of influenza vaccines: attenuated live vaccines and inactivated vaccines The two types of vaccines are used for different targets, and the characteristics and contraindications of the vaccine are also different. Before vaccination, explain your own situation to the doctor so that the doctor can well judge which technical route of flu vaccine is more suitable for the vaccinator; Stay on the scene for 30 minutes.
