According to South Korean media reports, as of October 26, South Korea has reported 59 deaths after receiving the flu vaccine. Although people are worried that the number of vaccinated people has dropped sharply, the government has not yet stopped it.
South Korean President Moon Jae-in said in a meeting at the Blue House that day that there has been confirmed that there is no direct causal relationship between deaths after receiving influenza vaccination and vaccination. In order to prevent influenza and the simultaneous infection and spread of influenza and the new crown, it is necessary to continue to expand the scope of influenza vaccination. I hope that the public will not miss the timely vaccination because they are too uneasy and accidentally get infected with the flu with a high mortality rate, which will lead to greater danger.
It is reported that most of the cases of death after receiving the flu vaccine are elderly people over 70 years old, and they die at least 4 hours after being vaccinated. There is also a 17-year-old teenager who died 2 days after receiving the vaccine.
Every winter and spring is the peak season for influenza. At present, the whole world is in the stage of the new crown epidemic. Experts such as Academician Wang Chen, Zhang Wenhong , etc. recommend getting influenza vaccination to avoid influenza infection, reduce the chance of going to fever clinics, reduce the chance of two viruses being infected with the combined infection, and reduce a hidden danger.
So, there are many people in our country who want to get influenza vaccines now, and there is a great demand for vaccines. So, how can we get vaccinated safely?
Why do you have serious adverse reactions after vaccination
First of all, one thing that must be confirmed is that the vaccine ingredients contained in the influenza vaccine will not cause influenza.
But at the same time, as a drug, influenza vaccine is not absolutely safe. There are a lot of possible adverse reactions, such as redness, swelling, hardness, pain, burning sensation at the vaccination site. A few people may have systemic reactions, such as fever, headache, dizziness, drowsiness, , fatigue, myalgia, general discomfort, nausea, vomiting, abdominal pain, diarrhea, etc. Most people have mild adverse reactions and can disappear on their own within 3 days. Serious adverse reactions are very rare. There is no difference in safety between the quadrivalent influenza vaccine and the trivalent influenza vaccine; there is no significant difference in safety compared with domestic and imported influenza vaccines. Adverse reactions may be related to the following three reasons:
, one is immune response. Because influenza vaccine is a drug made by inactivate, sterilize and lyse the influenza virus after processing, it will simulate the real virus inducing the body's immune response and prompt the body to produce antibodies. This immune response is often accompanied by various adverse reactions.
Second, during the production and preparation of influenza vaccines, trace amounts of endotoxins and impurities may remain.
three may be a coupling reaction. In other words, when injecting influenza vaccine, it may be just the incubation period of other diseases. After injecting influenza vaccine, the disease outbreak period will reach.
No matter what the cause is, if the body's immune response is too severe, or the original disease is aggravated and serious, and is not treated in a timely and properly, serious adverse reactions may occur.
One of the serious adverse reactions is Guillain-Barre syndrome (GBS). The annual incidence of GBS in the general population is 10 to 20 cases per 1 million adults, which is very rare.
Another type is rapid hypersensitivity reaction. Any vaccine has the risk of rapid hypersensitivity reactions. Severe allergic reactions may be life-threatening and occur rapidly. They usually occur within minutes to hours of vaccination. The symptoms include urticaria, angioedema , severe allergic reactions, etc. The incidence is usually 1 to 2 cases per million people.
Two types of people who are prone to adverse reactions
Adverse reactions after receiving influenza vaccine may occur. On the one hand, it may be related to the sensitivity of the immune system of people of different ages. Since children and young people are more sensitive, the invasion of harmful substances such as viruses in the body will trigger obvious immune reactions, so the chance of adverse reactions will increase; on the other hand, as they age, the elderly tend to suffer chronic pain and are stubborn and difficult to treat, so all kinds of pains that occur after vaccination will be covered up by chronic pain, so they think that they have no adverse reactions, which delays the treatment.
Children: The probability of adverse reactions after receiving influenza vaccine is higher than that of adults. The most common one is fever. The younger the age, the higher the probability of fever, but it usually disappears on its own after 1 to 2 days of vaccination. At the same time, the risk of fever convulsion in children will also increase within 1 to 2 days after vaccination.
Elderly: The most common adverse events in adults include injection site pain, fever, myalgia and headache; the elderly are the most common pain at the vaccination site, but the duration is generally less than 2 days, usually mild, and basically does not affect daily activities.
A large number of data show that inactivated influenza vaccine will not cause harm to pregnant women and fetus, and will not increase the risk of congenital malformations in the fetus.
Precautions for vaccination
Contraindications for influenza vaccine are those who are allergic to any ingredients contained in the vaccine (including excipients, formaldehyde, lysants and antibiotics); patients with mild and moderate acute diseases with or without fever symptoms are recommended to receive vaccination after the symptoms subside.
It should also be noted that people who are allergic to eggs are not currently considered a taboo, so people who are allergic to eggs can get influenza vaccine.
Influenza vaccine can be vaccinated during prevention and treatment of influenza antiviral drugs, and it is recommended that elderly people over 65 years old should receive both influenza vaccine and pneumococcal vaccine.
Common causes of adverse reactions are fasting, psychological factors, etc. The treatment method is to drink warm sugar water, keep warm and maintain a quiet and comfortable environment, and perform appropriate psychological adjustment. Local pain and swelling can be applied for local dry and hot compress; if respiratory symptoms such as dry mouth and cough can be relieved by drinking more warm water.
If you experience discomfort symptoms after vaccination, you should communicate with the doctors of the vaccinated institution in a timely manner. If the symptoms have not subsided for more than 3 days, please seek medical treatment in time.
In short, influenza has always been an infectious disease that endangers health, and now it is the COVID-19 pandemic. Influenza vaccination can not only protect oneself from influenza virus infection, but also play a good barrier for the occurrence of influenza in the population. Influenza vaccine should be actively vaccinated, especially high-risk groups such as the elderly, children, and pregnant women. #Moon Jae-in responded to 59 people who died after receiving the flu vaccine#
