The situation of the new crown epidemic in my country is different from that in other countries, and the vaccine use strategy is also different. The main strategy of new coronavirus vaccination needs to be considered in combination with the domestic epidemic situation and the goals of prevention and control. At present, the significance of vaccinating key populations is to protect this part of the population on the one hand, and on the other hand, it is conducive to "external import and internal prevention of rebound", and is conducive to my country's overall epidemic prevention and control.
At this stage, the key populations of new crown virus vaccination mainly include those who are engaged in import cold chain, port quarantine, ship piloting, aviation air service, fresh food market, public transportation, medical disease control, and other industries with a relatively high risk of infection; going to medium-to-high-risk countries or regions Work, study and other personnel.
Is it necessary to vaccinate against the new coronavirus?
necessary. On the one hand, almost everyone in our country has no immunity against the new coronavirus and is susceptible to the new coronavirus. After the infection occurs, some people will develop critical illnesses and even cause death. After vaccination, on the one hand, the vast majority of people can gain immunity; on the other hand, through orderly vaccination of the new coronavirus vaccine, an immune barrier can be gradually established among the population and the epidemic of new coronary pneumonia can be blocked.
How to get the new coronavirus vaccine and where to get it?
The vaccination of the new coronavirus vaccine is carried out in the vaccination unit approved by the local health administrative department. Normally, the vaccination unit is located in the health service center, township health center, or general hospital in the jurisdiction. If the vaccination involves some departments or enterprises where key objects are concentrated, the local area will also set up some temporary vaccination units according to the situation.
The health administrative department or disease prevention and control agency of the jurisdiction will also announce the vaccination units that can be vaccinated against the new crown virus as required, including the location and service hours. Please pay attention to the relevant information release platform.
For most key populations, the unit where the key populations are located will organize surveys, make appointments, and assist in carrying out the vaccination work. Individuals who go to work or study in high-risk countries or regions can pay attention to the relevant service information of the local new crown virus vaccination.
What are the contraindications for vaccination?
The contraindications of vaccination refer to situations in which vaccination should not be taken. Because most contraindications are temporary, the vaccine can be vaccinated at a later time when the conditions that caused the contraindication no longer exist.
Before the new crown virus vaccination plan and vaccination guidelines have made specific provisions, the contraindications of the new crown virus vaccine vaccination shall be implemented in accordance with the vaccine instructions. The usual contraindications for vaccination include 1. Those who are allergic to vaccines or vaccine components; 2. Those who suffer from acute diseases; 3. Those who are in the acute onset of chronic diseases; 4. Those who are feverish; 5. Women who are pregnant.
How to find and grasp the contraindications of vaccination?
During the implementation process, if a severe allergic reaction occurs during the first dose of the vaccine, and it cannot be ruled out that it is caused by the vaccine, the second dose is not recommended. To understand the ingredients of the vaccine, people who have been allergic to the ingredients of the vaccine should not be vaccinated.
During vaccination, the vaccination doctor should carefully ask about the recipient's health status and previous allergy history. Recipients should truthfully report their physical health, disease history, and allergy history to the vaccination doctor. Vaccine contraindications should be included in the informed consent form.
Do I no longer need to wear a mask after receiving the new coronavirus vaccine?
Before the population's immune barrier is established, even if some people are vaccinated, everyone's awareness of prevention and control and prevention and control measures cannot be relaxed. On the one hand, the success rate of vaccine immunization is not 100%, and a small number of people who have been vaccinated may become ill during the epidemic. On the other hand, in the absence of an immune barrier, the new coronavirus is still easy to spread. Therefore, you should continue to wear masks after vaccination, especially in public places and crowded places; other protective measures such as hand hygiene, ventilation, and social distancing also need to be maintained.
How to form herd immunity in the population through vaccination?
The infectivity of different infectious diseases is different, and the level of immunity of people who block the epidemic of infectious diseases is also different. Generally speaking, the stronger the infectious power of infectious disease, the higher the immunity of the population is required. For example, measles and whooping cough are highly contagious. If they are to be blocked, the population’s immunity must reach 90%-95%. To eliminate smallpox and polio, the population’s immunity must reach more than 80%. When the population’s immunity reaches the above threshold, an immune barrier is established to block the spread of measles, whooping cough, smallpox, and polio.
The immunity of the population is directly proportional to the protective efficacy of the vaccine and the vaccination rate. Therefore, to achieve sufficient population immunity, it is necessary to have a sufficiently high vaccination rate, that is, the vast majority of people are vaccinated. Conversely, if there are more people who do not vaccinate or most people are unwilling to vaccinate, a strong immune barrier will not be formed, and the spread of disease will easily occur when there is an infectious source.
How long is the protection of the new coronavirus vaccine currently in use in my country?
The new coronavirus vaccine is a newly developed vaccine that has been put into use. It requires continuous monitoring and related research after large-scale vaccination to accumulate more scientific evidence and evaluate the protection and durability of the new coronavirus vaccine.
After vaccination, how long does it take to produce antibodies against the new coronavirus?
According to previous clinical trials of inactivated vaccines for the new coronavirus, about two weeks after the second dose of inactivated vaccines, the vaccinated population can have a better immune effect.
What are the common adverse reactions to new coronavirus vaccination?
From the results of preliminary clinical trials of the new coronavirus vaccine and the information collected during emergency use, the occurrence of common adverse reactions of the new coronavirus vaccine is basically similar to that of other vaccines that have been widely used. Common adverse reactions mainly include redness, swelling, induration, and pain at the site of inoculation, as well as clinical manifestations such as fever, fatigue, nausea, headache, and muscle aches.
Terada hardware can better ensure that the customer's tensile fabric shade structure is completed on schedule by allowing 100% of its employees to inject vaccines. In this project, we provided a tensile rod system, D ring, and some tensile structure hardware to assist customers from the initial design stage to the final completion of the project. Vaccination of all employees can not only ensure the safety of our employees but also ensure that the products we produce will not carry the possibility of spreading the virus.
