Today, I was attracted by the above news. Every winter, it is the peak period for the masses to vaccinate the influenza vaccine . After the baptism of new coronary pneumonia, the influenza vaccine has attracted more attention and once received a shot. Hard to find. However, seeing the above news, vaccinations can cause death, is it suddenly a bit daunting? Let us analyze, can this vaccine still be used? What is the
flu vaccine? The
influenza virus can make people suffer from influenza , which is a very contagious respiratory disease with obvious symptoms and severe illness, and can cause death in severe cases. The flu vaccine is a "magic medicine" that can prevent people from getting sick. After the virus is inactivated or lysed, part of the "dead" virus is injected into the human body. At this time, the part of the virus fragment that enters the human body is not enough to cause the disease, but it can stimulate the human body to produce powerful antibodies. When influenza virus invades again, people who have been vaccinated can quickly mobilize enough antibodies to wipe out the virus. For people who have not been vaccinated, because they do not have these antibodies in their bodies, the virus can multiply in the body and cause the human body to get sick.

vaccine common adverse reactions
under normal circumstances, after vaccination, there will be no obvious symptoms of discomfort. A small number of people may have fever, rashes, and slight redness and swelling at the injection site due to physical differences, but these phenomena are relatively mild, and the duration is very short, and they can relieve themselves without special treatment. In very special circumstances, individual people will have high fever, dyspnea, wheezing, shock, coma, etc. This is a severe allergic reaction, which requires immediate emergency treatment, which usually occurs within a short period of time after vaccination. This is why after the vaccination, the doctor will keep the vaccinated person in the hospital for at least half an hour, and then leave after there is no adverse reaction.

Can vaccination cause death?
Although the vaccine is generally safe, there are always special cases outside of the general situation. Vaccination cannot guarantee 100% absolute safety. In the case of more than 70 deaths from influenza vaccination in South Korea, it is necessary to analyze the specific condition of each patient in order to clarify the cause and effect. Most of the cases are elderly people, and elderly people suffer from various diseases, even if vaccination factors are excluded, they may become worse or die due to other diseases. To say "death after vaccination" is extremely misleading. It is not stated how long after vaccination, what symptoms did you have, and how long after you died? It also did not indicate whether the patient himself had other diseases, the severity of other diseases, and whether they were fatal? Therefore, vaccination may cause death, but the probability is very, very very low, and other diseases must be excluded. On the contrary, the effective rate after vaccination is very clear.
vaccination
In summary, vaccination is generally safe. However, there are some special groups that cannot be vaccinated: pregnant women, severe allergies, people with immunodeficiency and , people with various diseases and unstable conditions, etc.
must be observed for at least half an hour after vaccination, and within three days, try to avoid allergic foods such as seafood, because if an allergic reaction occurs due to diet, it is not easy to distinguish from the allergic reaction caused by the vaccine.
