How big are the side effects of COVID-19 vaccine？ The doctor’s circle of friends broke the truth, and these three are more common.
Recently, the most common thing I heard was that there were confirmed cases in Covid-19, and the prevention and control measures were strengthened.
Fortunately, our vaccine came out in time, but it was followed by all kinds of rumors about the side effects of the vaccine flying all over the sky, and all kinds of so-called "secret recipes" to "kill" Covid-19 emerged one after another.
When it comes to vaccines, everyone is familiar with them. We have been vaccinated a lot since childhood. However, some time ago, when the first dose of COVID-19 vaccine began to be widely injected, my circle of friends was almost screened by the news of vaccination. As a doctor, there are quite a few medical staff in my circle of friends, but there are also many friends in other industries, so it is still representative.
Dr. Xin Lu Xing Chen: From the feedback of friends circle, most people say that they don’t feel anything after vaccination, and some friends don’t even feel pain after the injection. Apart from giving such good technical praise to the nurse, I guess it may be that this guy is stunned by the beautiful nurse.
However, some people say that the place where they hit will be painful, some will have small induration, and a few people feel a little tired or dizzy. They ask privately and will be fine in a day. At present, a friend said that he had a low fever after vaccination, but his temperature was normal the next day.
Therefore, through the feedback from friends circle, combined with the officially published research, it seems that the main common adverse reactions are as follows:
1. Pain, redness and induration at the inoculation site.
2. Fatigue and dizziness may also occur.
3, muscle aches, cough, fever, etc. Fever is rare, and it can be a transient low fever.
70% of adverse reactions occur within 24 hours after inoculation. Generally, most adverse reactions will disappear in a short time after rest and observation and hydration.
There are also some rare adverse reactions, such as anaphylactic shock, the incidence of which is very low.
Of course, there are still someMore rare and unknown "side effects"It exists on the network of friends, and it has no basis. It is sent only for scientific research:
At work, I often meet these colleagues and ask about their feelings about vaccination. Basically, they shrug their shoulders and say that they have no feelings, and some are quite awkward.Publicly clamoring that he is the "safest date"
This is quite awkward.
On the other hand, there are quite a few friends who have had the second injection recently. Let’s take a look at it and summarize it later. Of course, my circle of friends is still limited after all. Although the overall adverse reactions are similar to other vaccines in the past, it cannot be ruled out that individuals may have more serious reactions. So, what circumstances need to come to the hospital after vaccination?
1, fever over 38.5°C, persistent, especially with severe systemic symptoms.
2, local swelling diameter < ＜1.5cm generally do not need to be treated. Larger ones can be locally compressed several times a day for 10~15 minutes each time. If it is ≥3cm, you should seek medical advice in time to rule out local inflammation.
3, severe allergic rash, anaphylactic shock, etc. (so after the vaccination, you should stay on observation for 30 minutes).
In addition, a friend asked me if I could get other vaccines at the same time.
Answer: No, if you want to inject other vaccines, the interval should be at least 2 weeks. In this information age, all kinds of knowledge on the Internet are true or false. When the COVID-19 vaccine came out, rumors were flying all over the sky. Many people rumored that they were making mice as experiments. But if you think about it, you will know that at present, all the first-line personnel are vaccinated, and quite a few are medical personnel. Who would be so stupid and deliberately disabled all the first-line personnel? Then who will fight Covid-19? So this is a rumor that can’t stand scrutiny.
and Inactivated vaccine is currently used in China.Is obtained by inactivating and purifying Covid-19 cultured in vitro. These inactivated viruses are already dead and have no pathogenic ability, but they can still stimulate our body to have an immune response and produce antibodies.
In layman’s termsAfter the inactivated fake virus enters the human body, it can teach the immune system to know this virus. Next time if you encounter a real virus, the immune system will take a look:Ah, this guy looks familiar.Check the computer network. Oh, this is a terrorist with a criminal record, so I went to the armory and pulled the corresponding one.antibodySniper rifle,"Bang bang bang"Just kill it.
This is a very mature technology, and many vaccines we usually inject use this technology. No matter from the official statistics or from the situation around us, our vaccine in China is relatively safe. After all, even Zhang Wenhong’s bosses in Shanghai and many foreign heads of state have played, and they are all closest to the information center. They are all vaccinated. Isn’t that the best explanation for safety?
So after producing antibodies, is the effect good? How long can you protect us?
According to statistical analysis, the neutralizing antibody positive conversion rate of our inactivated vaccine was 99.52% after two doses of immunization program, and the protective effect of the vaccine on diseases caused by Covid-19 infection was 79.34%.
Everyone is also very concerned about the protection time of human body, but because the vaccine has only been observed for 8 months, it shows that the protective antibody can still maintain a high level, so the prospect is still optimistic.
According to the previous answers of experts from China CDC, there can be at least a protection period of more than half a year, and the follow-up protection needs relevant research to determine. So it is no problem to spend the most dangerous months in winter after vaccination.
Recently, the methods of drinking tea and drinking alcohol to resist virus have been circulated on the Internet, which is said to have a 99.9% killing rate of the virus.
This rumor was popular when the virus first came out last year, and there is no evidence so far, so we just have the right to listen to it as a joke. Of course, if people can be soaked in tea or white wine for a period of time according to the test standards, it may be really effective, but at that time, it seemed that people and viruses were burned to death, right?
This winter is quite cold, but the heart to fight the epidemic is fierce, and the circle of friends is also very hot. The ridicule is relaxing, but we are rigorous in medical science!
