Don't be stopped by these rumors
Refute rumors
◎Intern reporter Yu Ziyue
Since the beginning of this year, domestic vaccination work on the new crown vaccine has been carried out in an orderly manner.
Official data show that as of April 12, 31 provinces (autonomous regions, municipalities) and the Xinjiang Production and Construction Corps have reported a total of more than 170 million doses of the new crown vaccine.
When the vaccination work was carried out in an orderly manner, there were many rumors about the new crown vaccine on the Internet: you can take off the mask after the new crown vaccine, you can not get the new crown vaccine for allergies, and you will have a fever and swelling face after the new crown vaccine... these statements I wonder how many did you believe?
Can I take off my mask after getting the new crown vaccine? The truth: protective measures such as wearing masks are still needed
Masks are a great hero in preventing the spread of the new crown virus.
Recently, there have been rumors that the mask can be taken off after being vaccinated with the new crown vaccine, "the bird will hide in the bow".
is this real?
In this regard, Feng Zijian, deputy director of the Chinese Center for Disease Control and Prevention, gave a negative answer at the press conference of the Joint Prevention and Control Mechanism of the State Council.
Feng Zijian said that there are two issues that need to be considered: on the one hand, the current global epidemic has not completely subsided; on the other hand, my country's vaccination rate is still low, and there is still a long way to go from a high level of population immunity.
Based on this, the entry of people from high-endemic areas or the entry of their articles may still cause the spread of the new coronavirus in the country.
Moreover, relevant experts said that the protection rate of any vaccine is not 100%, and the same is true for the new crown vaccine.
Therefore, even if vaccinated, the risk of infection with the virus is greatly reduced, but it is not completely impossible for infection.
The epidemic has not completely subsided, and the public should not take it lightly.
"Before the new crown vaccination rate in our country reaches a high level, the general public must still strengthen their awareness of protection and develop good personal hygiene habits. Regardless of whether they are vaccinated or not, they must continue to wear masks in crowded indoor or closed places. , And follow the specific prevention and control measures requirements of various localities." Feng Zijian said.
The new coronavirus will mutate, and the vaccine is useless? The truth: vaccines are not in vain, they can build a basic immune barrier
"The current vaccine is only for the current epidemic of the new coronavirus. After the virus mutates, the vaccine is useless." said a Beijing citizen who was randomly interviewed by a reporter from Science and Technology Daily on April 9.
Recently, there are not a few people who hold this view, and many people have this view.
So, after the new coronavirus mutates, will the vaccine really be a waste?
In this regard, Shao Yiming, a researcher at the Chinese Center for Disease Control and Prevention and a consultant to the World Health Organization's Vaccine Research and Development Committee, made it clear in an interview with the media that the new crown vaccine will not be in vain.
Shao Yiming said that in the face of the new coronavirus variant, the level of neutralizing antibodies induced by the new coronavirus vaccine may decrease, that is, the protective efficacy of the vaccine may decrease.
However, as long as the vaccine is vaccinated, the vaccine will build the basic immunity against the new coronavirus for the vaccinated.
Even if the ability of the virus variant strain to escape the vaccine barrier becomes stronger, a new variant strain vaccine can still be given as a booster shot.
In this way, the booster injection can quickly stimulate the body's immune protection against the mutant virus based on the existing immunity.
According to media reports, a research report recently released by the Butantan Institute in the State of Sao Paulo, Brazil, shows that the Claive Covid-19 vaccine developed by China and Brazil can effectively fight the mutant new coronaviruses that have emerged in Brazil, the United Kingdom and South Africa.
Researchers extracted serum from vaccinated volunteers and placed it in a petri dish together with the mutant virus. The results showed that the antibodies in the serum can effectively fight the mutant virus.
In addition, according to the latest information released by the World Health Organization, from the global monitoring of the mutation of the new coronavirus, there is no evidence to prove that the existing new coronavirus vaccine will be invalid in the face of the virus variant.
Will you have a fever and face swelling after being vaccinated with the new crown vaccine? The truth: the incidence of adverse reactions is low
The number of doses of "170 million" seems to be a lot, but in fact, due to the large population of our country, the domestic vaccination rate is much lower than that of the United Kingdom and the United States. Herd immunity can only be generated when the new crown vaccination rate reaches 70% to 80%.
Obviously, the number of vaccination doses in our country is far from enough. What's more, the "170 million" also includes multiple doses for a single person.
It can be seen that some people are still hesitating about whether to vaccinate. One of the main reasons is that they are worried about adverse reactions.
Some netizens left messages saying that they would have fever and face swelling after being vaccinated with the new crown vaccine, but is this really the case?
Wang Huaqing, chief expert on the immunization program of the Chinese Center for Disease Control and Prevention, once stated at a press conference of the Joint Prevention and Control Mechanism of the State Council that the new crown vaccine is a foreign antigen to the human body.
Taking into account the characteristics of the new crown vaccine itself and individual differences, some adverse reactions may occur after vaccination, but the overall incidence is relatively low.
In other words, not everyone will have adverse reactions after being vaccinated with the new crown vaccine, and only a small number of people will have symptoms of discomfort.
So what are the common adverse reactions after vaccination with the new crown vaccine?
A few days ago, a reporter from Science and Technology Daily signed the "Informed Consent for Vaccination of New Coronavirus Inactivated Vaccine" at the time of community vaccination. It clearly pointed out that the local adverse reactions after vaccination were mainly pain at the vaccination site, including local itching and swelling. , Induration and flushing, etc. The main systemic adverse reactions are fatigue and fatigue, and also include fever, muscle pain, headache, cough, diarrhea, nausea, anorexia and allergies.
After the vaccination is completed, the vaccinated person must stay at the vaccination site for 30 minutes before leaving if there is no abnormality.
The on-site staff will inform the recipients of the common adverse reactions and precautions of the new coronavirus vaccine. If the recipients have a fever or continue to be unwell after returning home, they should report to the vaccination site and seek medical attention in time.
Can't get a vaccine for allergies? The truth: general allergies are not contraindicated in vaccination
On March 29, the official website of the National Health Commission released the "New Coronavirus Vaccination Technical Guidelines (First Edition)" (hereinafter referred to as the "Vaccination Guidelines"), which listed five types of vaccination contraindications, two of which are related to Allergic reactions are related.
Therefore, there are rumors that people with allergies cannot get the new crown vaccine. Is this true?
In this regard, An Zhijie, deputy director of the Immunization Program Center of the Chinese Center for Disease Control and Prevention, said that general allergies, such as allergic rhinitis, pollen allergies, etc., are not directly related to the new crown vaccine components and are not in the scope of vaccination.
There are also people who are allergic to antibiotics such as penicillin. Can these people get the new crown vaccine?
In this regard, An Zhijie pointed out that the current new crown virus vaccine does not contain antibiotics, so antibiotic allergy is not a contraindication to vaccination.
It is worth noting that the two types of allergy-related vaccination contraindications pointed out in the "Vaccination Guide" include: those who are allergic to the active ingredients of the vaccine, any inactive ingredients, substances used in the production process, or those who have previously received similar vaccines People with allergies from time to time; people who have had severe allergic reactions to vaccines in the past, such as acute allergic reactions, angioedema, etc.
In a nutshell, people who are concerned about this must first distinguish their allergies and consult professional physicians for vaccination recommendations.
Are different brands of vaccines ineffective? Truth: No research data for the time being, special circumstances can be used to fight
At present, my country has 4 kinds of new crown vaccines approved to be marketed conditionally, of which 3 are inactivated vaccines and need to be vaccinated twice; 1 is an adenovirus vector vaccine and only needs to be vaccinated once.
There is also a recombinant protein vaccine approved for emergency use, requiring 3 doses.
For vaccines that require multiple doses, there are rumors that different brands of vaccines are not effective.
Is it really the truth?
Previously, He Qinghua, the first-level inspector of the CDC of the National Health Commission, said that more research is needed on whether vaccines produced by different companies can be superimposed or replaced.
After the research results come out, the relevant departments will put forward clear policy measures based on the research results.
Subsequently, the "Vaccination Guide" was released, giving a clearer answer: at this stage, it is recommended to use the same brand of vaccine products to complete the vaccination.
In case of special circumstances such as the inability to continue supply of vaccines and the recipients are vaccinated in different places, and the same vaccine product cannot be used to complete the vaccination, the same type of vaccine product from other manufacturers can be used to complete the vaccination.
"Currently, all domestically marketed COVID-19 vaccines have been reviewed and approved by the competent government departments and are safe and effective. The public can vaccinate as soon as possible in accordance with the unified arrangement of the region." He Qinghua said.
