Influenza is mainly two types of infection, with more symptoms, and may even cause serious illness

Influenza is different from the common cold. The most important specificity of influenza is epidemic and contagious. Influenza is an acute respiratory infection caused by influenza viruses. There are four types of influenza viruses (A, B, C, D or ABCD), but only types A and B will cause the prevalence of seasonal influenza, including two subtypes of H1N1 and H3N2, and two subtypes of influenza B viruses, Victoria and Yamagata.

Influenza may cause symptoms of patients including fever, headache, muscle aches, fatigue, runny nose, sore throat and cough . The above are just mild symptoms of influenza, similar to common colds; for moderate and severe cases, infected people will have gastrointestinal symptoms such as nausea, vomiting and diarrhea (similar to gastrointestinal cold symptoms), and may even lead to pneumonia , encephalitis , myocarditis , nephritis and other serious secondary infections or neurological diseases. If these moderate and severe cases have no obvious signs, the infection will have a triggering chance. Injecting influenza vaccine can help reduce the chance of infection.

Injection vaccine is inactivated vaccine . Generally, the side effects are small and manufacturers are different. If you have a choice for injecting the vaccine, you can confirm with the epidemic prevention agency and choose a manufacturer that you feel safe injecting the vaccine.

The elderly should get influenza vaccine. Influenza vaccine prevents severe illness and reduces mortality rate.

Influenza vaccine may vary from age or physical condition to protect people, and has a large fluctuation in efficiency, generally around 30% to 80%. The protective power for adults over 18 years old is about 40% hospitalized due to confirmed flu, and the protective power for severe influenza in the ward can reach more than 80%.

htmlThe protection of influenza vaccine for children and adolescents aged 06 months to 18 years old is similar to that of adults, but for the elderly, it can reduce the chance of 50% to 60%. For severe influenza complications and 80% of the mortality rate. Therefore, the elderly should get influenza vaccine regularly to protect themselves.

It should be noted that getting influenza vaccine requires more than 7-14 days to be separated from new crown vaccine , and actively inform yourself of your vaccination history before getting influenza vaccine. What are the common side effects of influenza vaccine for

?

Although the flu vaccine has been used for so many years, it does not mean that there are few side effects. The common side effects are mainly as follows:

1, mild side effects of vaccine

mainly show that the injection site is red, swollen and painful, and a few people will have mild systemic reactions, such as: fever, headache, muscle aches, nausea, skin itching, rash , etc. These symptoms generally recover naturally within 1-2 days after the injection of the vaccine.

2, severe side effects of vaccine

These side effects generally appear within a few minutes to a few hours after injection, including acute allergic reactions, allergic shock ( dyspnea , hoarse voice, swelling of eyes, dizziness and heartbeat, wheezing, etc.). The incidence of these symptoms is very low, and it usually occurs at a lot of time. Therefore, after injection, the medical institution will allow the injector to rest for half an hour before leaving. If the above serious symptoms appear after vaccination, seek medical treatment immediately.

4 major precautions for influenza vaccine

In order to prevent the harm of potential side effects of influenza vaccines, vaccine injectors should pay attention to four aspects:

1. After vaccination, there is a small chance of allergic reactions and eventually lead to allergic shock. In order to be able to treat medical treatment immediately after the incident, you should wait at the injection institution for at least 30 minutes before leaving after getting vaccinated.

2. Use antiplatelets, anticoagulant drugs or people with abnormal coagulation dysfunction . After injection, press the pinhole for a period of time to avoid bleeding or hematoma.

3. After vaccination, you should pay attention to whether there is a persistent fever. should generally pay special attention to it for more than 2 days. In addition, if the symptoms include abnormal conditions such as dyspnea, fast heartbeat, awareness or behavior changes, you should seek medical treatment immediately and inform the doctor of the vaccination status during treatment.

4. After completing vaccination, although it can effectively reduce the risk of influenza virus infection, it may still be infected with other respiratory infections , such as pneumonia and other . You should not be careless, especially during the epidemic.

In addition to the above precautions, many people have some misunderstandings about influenza vaccine injections, believing that they rarely get sick and do not need to get influenza vaccine; or they used to be often given, but now they can be slow, and they will be given again in two years, etc. So, which of these statements are correct?

5 misunderstandings about getting influenza vaccination

1. Can’t you catch a cold if you get influenza vaccination?

Many people believe that the symptoms of influenza and cold are similar. If you get the flu vaccine, you will avoid a cold and you will not get any cold. In fact, the pathogens of general colds may come from hundreds of different viruses and bacteria, which are different from influenza. Generally, colds may not have strong infections, but it does not mean that vaccines are effective for all colds.

In addition, there are individual differences in the protective effects produced after influenza vaccination, and a few people may also suffer from colds or other influenza viruses when their protective power is insufficient. In addition, after completing the influenza vaccination, protective strength will not be produced after at least 2 weeks, and it will not be effective immediately after vaccination.

2. You don’t need to get influenza vaccinated if you get sick very rarely?

For influenza, everyone may suffer from influenza. Only the risk of illness is different and the severity of symptoms is different. Even if few people get sick, they will still get sick if they are infected with influenza virus. Therefore, the best way to fight influenza is to get one influenza vaccine every year.

Although most people infected with influenza have mild symptoms and can recover within about one week, since high-risk groups such as the elderly, children and chronic patients are prone to complications after suffering from influenza, such as pneumonia, nephritis, encephalitis, myocarditis, and even death, this type of population should pay special attention and it is recommended to receive influenza vaccine regularly every year to prevent complications caused by influenza.

3. Can’t get the flu vaccine if you have a cold?

Since influenza vaccine is an inactivated vaccine, that is, the virus in the vaccine is an inactive virus, even if the injector has mild diseases such as colds, diarrhea, and allergies, it will not affect vaccination. However, if several more serious problems occur before vaccination, it is recommended to postpone vaccination first. After the symptoms are cured or the condition is stable, then consider vaccination. For example,

Fever

Have serious diseases (such as cancer)

Immunity deficiency or long-term use of drugs that inhibit immunity (such as steroids or anti-cancer drugs)

Allergic to vaccine components

Have had serious side effects on influenza vaccine

4. I was given influenza vaccine last year, so I don’t need to be given this year?

Due to the strong variability of influenza viruses, the virus strains that are popular every year are slightly different. The last vaccine is not immune to viruses of different antigenic types, and the protection effect will also be reduced accordingly.

In addition, even if the influenza virus has not mutated, the vaccine composition is the same, but the protective effect may decrease after 4-6 months of vaccination. Usually, the protective power does not exceed 1 year, so it is recommended to vaccinate once a year.

5. Can influenza vaccine be administered with other vaccines?

influenza vaccine will not interfere with its inactivated vaccine. You can be vaccinated at the same time, or you can get vaccinated at a time, such as the common childhood vaccines such as Streptococcus pneumonia vaccine and Japanese encephalitis vaccine. However, in order to prevent side effects, it is best to inform the doctor whether you have received other vaccines in the near future before vaccination.

Due to the COVID-19 pandemic, some people may consider getting the COVID-19 vaccine in addition to getting the flu vaccine. In order to avoid side effects, it is recommended that the vaccination time between the influenza vaccine and the COVID-19 vaccine should be at least 7 days apart, preferably 14 days.
