Hi, opponents of the vaccine – these 7 responses to the flu are special for you

Daniel Huber /

Many people do not want to be vaccinated – for various reasons. However, a very infectious influenza ("influenza") is often underestimated because you like to confuse them with a significantly harmless influenza infection ("cold"). Grip seriously weakens the immune system and can cause complications that endanger life.

Although the vaccine does not provide 100% protection against infection, it is the best medicine for flu. The vaccine is most effective if taken before the onset of the flu episode – preferably from mid-October to mid-November. It is recommended for those who want to protect themselves and do not want to infect others. If you belong to a risk group (see point 5), vaccination is urgently needed.

How effective is the flu effect?

The vaccine can not provide absolute protection because influenza viruses mutate so that the immune system can not always reliably detect and counteract. The effectiveness also depends on which viruses circulate and whether the vaccine covers them. Coverage varies from year to year, but often exceeds 90%.

In addition, other factors such as the age of the vaccine affect efficiency – it is lower in the elderly. Accordingly, vaccine efficacy for a particular season can not be accurately quantified – according to the Federal Institute for Public Health (FOPH) it is reduced to health
younger adults at risk of a disease of 70-90 percent, in the elderly
30-50 percent.

However, if it is a disease in spite of the vaccine, the symptoms are often
weakened. In addition, severe complications occur less often.

Can the vaccine have side effects?

Yes. In about a third of vaccinated individuals, redness and mild ischemia or pain at the injection site occur. They are interrupted within a few hours to two days and do not require any treatment.

Rash, edema, allergic asthma or – usually with an already existing allergy – are rarely associated with severe allergic reactions. If you suffer from serious side effects, you should see a doctor.

Very rarely comes the Guillain-Barre syndrome (GBS) – approximately in one million cases vaccinated. However, GBS occurs more often due to the complication of influenza infection. The vaccine thus protects more than GBS than it starts. In any case, the risk of developing influenza causes serious complications is much greater than in the case of serious adverse effects of the vaccine.

Can a vaccine cause a flu?

No, that's not possible. The vaccine, which stimulates the immune system to produce specific antibodies, consists of fragments of inactivated viruses from different types of influenza virus. You can not cause the flu.

Why do immunized people sometimes have symptoms like flu?

Five reasons can lead to:

Insufficient coverage: If the vaccine does not cover the circulating viral strain, it provides only partial protection.

Low protection: Primarily in elderly or immunocompromised individuals, only the immune system of the weak body develops after vaccination, and they are then only partially protected. However, if they get flu, the symptoms are less and less likely to cause complications.

Vaccination time: It takes about two weeks for the immune system to develop. At this moment you can be infected.

Undesirable effects of vaccination: Five to ten percent of the vaccinated can react with fever, muscle aches or mild weaknesses. These symptoms are usually harmless and disappear after a short time.

cold: It is often harmless to the flu due to flu because the symptoms are similar. However, colds rarely cause complications.

Who needs to be vaccinated?

Those belonging to the risk group should be vaccinated. This refers to:

  • People over 60 years old
  • Pregnant women from the second trimester (then the baby is protected during the first months of life)
  • A six-month baby food during the first two seasons of the flu
  • chronically ill
  • People with overweight with BMI over 40 years
  • medical staff and carers, because they have an increased risk of infection. They also have a higher risk of infecting patients.
  • Residents of retirees and care homes

Where we are talking about health:

Should I be vaccinated, even if you do not belong to a risk group?

If you come into contact with people at home or at work who are at greater risk for complications, you should be vaccinated. How to prevent you from infecting such vulnerable people.

In healthy children and healthy young adults, seasonal flu usually goes without complications. Her symptoms are unpleasant. In addition, vaccination in autumn can prevent, for example, during winter holidays, flu.

When do they need to be vaccinated?

Those who have had a severe allergic reaction to any vaccine in the previous flu shot should not be vaccinated. This also applies to people who are very allergic to eggs.

If you have a high temperature, you should wait with the vaccine until it crashes. Otherwise, the protection of the vaccine could be reduced.

By contrast, during pregnancy and lactation, the flu vaccine can be done without hesitation. It is recommended to protect the mother and infants from influenza.
