This winter, the most concerned topic among the people is the vaccination of the new crown vaccine.
Regarding the new crown vaccine, many people are still skeptical and are unwilling to get the vaccine.
Some people are afraid that there will be side effects after the COVID-19 vaccine is administered;
Some people are worried that the new coronavirus has been mutating and the effectiveness of the vaccine cannot be guaranteed;
Some people also think that after getting the vaccine, they still have to wear a mask, which is useless.
People still have many concerns about the new crown vaccine, so the editor has specially compiled this collection of new crown vaccines to relieve everyone's concerns.
Concern 1:
Which vaccine do we get? Is it safe?
At present, the inactivated vaccine for emergency use in my country is two models of Chinese medicine, one of from Sinovac. Among them, Zhejiang Province, which was the first to start vaccination, used the inactivated vaccine from Beijing Sinovac.
Adverse reactions observed in China's inactivated vaccine mainly include: headache and fever, local redness at the vaccination site, or lumps , and some people have cough, loss of appetite, vomiting, diarrhea and other adverse reactions.
Since July, my country has carried out more than 41 million doses of new crown vaccine emergency vaccination for high-risk exposed people. After strict monitoring and tracking of adverse reactions, there were no serious adverse reactions in . More than 60,000 people in went to high-risk areas abroad, and no serious infections were reported in .
So overall, the vaccination response of new crown vaccine is not large and is within the normal range.
From another perspective, the vaccine is an alien antigen after all, and there will inevitably be some inconvenience with the body.
There are two situations: one is called adverse reaction , which refers to the occurrence of harmful reactions such as fever and nausea after standardized vaccination. All drugs, including vaccines, will produce adverse reactions, which is within the allowable range.
There is also a kind of coupling reaction , which means that the vaccinator happens to be in the incubation period of certain other diseases when he is vaccinated. During vaccination, the disease happens to be sick. This situation has nothing to do with vaccination or vaccine quality, and it does not constitute an adverse reaction.
So, first, the vaccine cannot 100% guarantee that there will be no adverse reactions, and second, based on the current clinical experimental data, the adverse reactions of the new crown vaccine are still within the normal range, and can be understood to be safe to a certain extent.
Concern 2:
virus has mutated, can the "old" vaccine still prevent "new" virus?
From a virus perspective, virus mutation is a normal phenomenon . Generally speaking, this mutation will not affect the severity of the disease, the infectiousness of the disease, nor will the immune effect of the vaccine on the virus.
China's vaccine research and development has collected 100,000 viral gene sequences from 6 continents and 105 countries. According to the current research results, the mutation changes of the new coronavirus are still within a normal range.
From the perspective of vaccines, China's vaccine types are mainly divided into: inactivated vaccine and adenovirus vector vaccine.
inactivated vaccine is made by selecting pathogens with strong immunogenicity and killing viruses by physical or chemical methods. There are many epitopes on inactivated viruses, which are enough to induce immune protection, and the virus mutation has little effect on its effectiveness.
adenovirus vector vaccine mainly targets the "S protein (spike protein)" on the surface of the new coronavirus. Therefore, as long as the S protein of does not undergo significant mutations, will basically not affect the effectiveness of the vaccine. We have no worries about this at present.
In short, the new crown vaccine currently developed can basically effectively cover virus mutations.Even if more mutations occur in in the future, we can quickly upgrade based on the current vaccine of , so everyone is not worried that the "old" vaccine cannot cure the "new" virus.
Concern Three:
Still need to wear a mask when you go out after getting the COVID-19 vaccine. What's the use?
- Sinopharm Zhongsheng The inactivated vaccine developed in Beijing is effective 86%
- US Pfizer , Germany Biotech, and China Fosun mRNA vaccine developed in is effective 95%
- The mRNA vaccine developed by the United States, developed by the Murdner has an effective efficiency of 94.5%
(data source: Global Times, CCTV News)
, such a set of effective data, has an effective efficiency of 86%, 95%, and 94.5%, and to a certain extent, has proved the effectiveness of the new crown vaccine.
In addition, the criteria for measuring whether the new crown vaccine is effective are also not only limited to individual . Professor Roy Anderson of the Imperial College of Technology in the UK said that if the new crown pneumonia vaccine is 90%, then the vaccination rate of 66.7% can achieve herd immunity (in the case of R0=2.5); if the is 70%, then the vaccination rate of 85.7% can achieve herd immunity.
can be seen. How much effect vaccination plays is not only whether individuals will be infected, but also how many people will be vaccinated. The more people are vaccinated, the wider the immune barrier formed, the more conducive it will be to achieve herd immunity as a whole for humans.
So when the current herd immunity has not been established, we still need to be vaccinated at , and protective measures must still be taken.
Therefore,
Can the new crown vaccine be vaccinated or should I get it?
At the joint prevention and control press conference, the news is that the new crown vaccine is expected to be launched at the end of December 2020 as soon as possible, and some places in China have begun emergency vaccination.
For example, Zhejiang Jiaxing, Shaoxing , Yiwu and other places have opened new crown vaccine appointments and used the vaccine for emergency vaccination.
Other regions are also actively implementing various measures to provide convenient services for the people to get vaccinated. Generally speaking, the vaccination unit has health service centers, township health centers or comprehensive hospitals in the jurisdiction. After
and other products are officially launched, is usually distributed, organized and notified to the public by the disease control system. everyone can pay more attention to the relevant information of local disease control and community health service centers.
Judging from the current open appointment situation, the new crown vaccine requires to be vaccinated twice, with a interval of 2-4 weeks. The price of the vaccine is RMB 200 per unit, and there is a service fee of 28 yuan each time. After , it costs 456 yuan to , which is not expensive.
At present, it is not recommended to get for children and pregnant women with new crown vaccine , because the new crown vaccine has not been fully promoted, and its suitable population is not yet clear yet, and we still need to wait for the official notice; in addition, before the national guidelines and plans are announced, it is recommended that new crown vaccine and HPV vaccine not be vaccinated at the same time.
Here, I would like to remind all vaccinators that during the vaccination process, you must truthfully report your personal health status to medical staff, what basic diseases do have, are you in the onset of the disease, whether you have any allergies, etc.
In addition, according to previous vaccination experience, these adverse reactions often occur within 30 minutes after vaccination, so vaccinators must stay at the vaccination site for 30 minutes after vaccination. After 30 minutes, you can go home without any problems.
After returning home, even if symptoms related to adverse reactions occur, you should seek medical treatment in time. At the same time, we should also remind all vaccinators to pay attention to diet and rest, and keep the vaccination site clean and dry.
Currently, only some areas in Zhejiang have opened COVID-19 vaccine appointments, and there is no news in other cities.Friends, don’t worry. The current vaccine is emergency vaccination. Whether it can be fully liberalized in the future, we still have to wait for the results of the third phase of the experiment. During this period, we must still take personal protection, wear masks in public places, maintain social distance, wash hands frequently, etc., and protect ourselves and the people around us.
