Many people do not want to get vaccinated – for different reasons. However, the highly contagious influenza ("influenza") is often underestimated, because you like to confuse them with a significantly harmless flu infection ("cold"). The flu severely weakens the immune system and can cause life-threatening complications. Although the vaccine does not provide 100% protection against infection, it is the best cure for the flu. The vaccine is most effective if taken before the onset of the flu episode – preferably between mid-October and 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 required. How effective is the flu vaccine The vaccine can not provide absolute protection because the influenza viruses mutate so that the immune system can not always reliably detect and combat it. Efficacy also depends on which viruses circulate and whether the vaccine covers them. The coverage varies from year to year, but often exceeds 90 percent. In addition, other factors such as the age of the vaccinee influence the effectiveness – it is lower in the elderly. Therefore, the effectiveness of the vaccine for a particular season can not be quantified exactly – according to the Federal Office of Public Health (FOPH) it lowers in healthy
younger adults the risk of disease by 70-90 percent, in seniors around
30-50 percent. However, if it comes to a disease despite the vaccine, the symptoms are often
weakened. In addition, severe complications occur less often.Can the side effects have? Yes. In around one third of the vaccinated persons, redness and slight swelling or pain occur at the injection site. They subside within a few hours to two days and require no treatment. Nausea rash, edema, allergic asthma or – usually with allergy already present – are more rarely associated with a severe allergic reaction. Those who suffer from severe side effects, should consult a doctor. Extremely rare it comes to a Guillain-Barré syndrome (GBS) – approximately in one case to a million vaccinated. However, GBS occurs much more often as a result of a complication of a flu infection. The vaccine thus protects more from GBS than it triggers. In any case, the risk that the flu causes serious complications is much higher than that of serious side effects of the vaccine. Can the vaccine trigger the flu? No, that is not possible. The vaccine, which stimulates the immune system to produce specific antibodies, consists of fragments of inactivated viruses from various influenza virus strains. You can not cause flu. Why do vaccinated people sometimes have flu-like symptoms? Five reasons can lead to this: Insufficient coverage: If the vaccine does not fully cover the currently circulating viral strains, it offers only partial protection.Small protective effect: Primarily in the elderly or immunocompromised individuals, only a weak body will develop after vaccination Immune defense and they are then only partially protected. However, if they get flu, the symptoms are less and less likely to cause complications. Timing of vaccination: It takes about two weeks for the body's immune system to develop. In this time you can be infected. Side Effects of Vaccination: Five to ten percent of those vaccinated may experience fever, muscle pain, or a mild feeling of illness. These symptoms are usually harmless and disappear after a short time. Cold: Often a harmless cold is mistaken for the flu because the symptoms are similar. However, colds rarely cause complications. Who should be vaccinated? Who belongs to a risk group should be vaccinated. This applies to: People over 60 years pregnant from the second trimester (then the baby is protected in the first few months of life) preterm infants from the age of six months during the first two flu seasonschronisch Ill obese people with a BMI over 40 medical staff and caregivers, because they have one increased risk of infection. They are also at greater risk of infecting patients. Residents of retirement and care homes
Speaking of health: Should you get vaccinated even though you are not a member of a high-risk group If you come into contact with people at home or at work who are at an increased risk for a complication, you should get vaccinated. How to prevent you from infecting such vulnerable people. In healthy children and healthy younger adults, the seasonal flu usually goes without complications. Her symptoms are uncomfortable. In addition, a vaccination in the fall can prevent, for example, during the winter holidays, the flu. When to NOT vaccinate Anyone who has had a severe allergic reaction to any of the vaccine in a previous flu shot should not be vaccinated. This also applies to people who are very allergic to egg white. If you have a high fever, you should wait with the vaccine until it has subsided. Otherwise the vaccine protection could be reduced. In contrast, during pregnancy and lactation, the flu vaccine can be made without hesitation. It is recommended to protect the mother and the newborn from the flu infection.
