Hello, opponents of vaccines: these 7 answers for the flu are especially for you

Daniel Huber / watson.ch

Many people do not want to be vaccinated for different reasons. However, highly contagious flu ("flu") is often underestimated, because you want to confuse them with a significantly harmless ("cold") influenza infection. Flu influences the immune system severely and can cause life-threatening complications.

Although the vaccine does not offer 100% protection against the infection, it is the best cure for influenza. The vaccine is most effective if taken before the start 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 urgent.

How effective is influenza vaccine?

The vaccine can not provide absolute protection because the influenza viruses mutate so that the immune system can not always be able to detect and fight reliably. Efficacy also depends on the viruses circulating and the vaccine is covered. Coverage varies from year to year, but often exceeds 90 percent.

In addition, other factors such as the age of the vaccine influence efficacy: it is lower in the elderly. Therefore, the effectiveness of the vaccine for a given season can not be quantified exactly – according to the Federal Public Health Office (FOPH) that reduces the health
Young adults the risk of illness in 70-90 percent, in the elderly
30-50 percent.

However, if it is a disease despite the vaccine, the symptoms are usually
weakened In addition, serious complications occur less frequently.

Can the vaccine have side effects?

Yes In about one-third of people vaccinations, redness and a slight swelling or pain occur at the injection site. They disappear in a few hours up to two days and do not require any treatment.

Eruption of nausea, edema, allergic asthma or, usually with allergies already present, are rarely associated with a serious allergic reaction. If you suffer from severe side effects, you should see a doctor.

Very rarely it is a Guillain-Barré syndrome (GBS), approximately in a single case of one million vaccinated. However, GBS occurs much more often as a result of a complication of a flu infection. The vaccine thus protects more than the GBS that triggers. In any case, the risk of influenza causing serious complications is much higher than that of the serious side effects of the vaccine.

Can the flu activate the vaccine?

No, this is not possible. The vaccine, which stimulates the immune system to produce specific antibodies, consists of fragments of inactivated viruses from several strains of influenza viruses. It can not cause flu.

Why do people sometimes have flu-like symptoms?

Five reasons can lead to:

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

Low protection: Mainly in older or immunocompromised people after vaccination only one immune system of the weak body arises and are then only partially protected. However, if you get the flu, the symptoms are less and less likely to cause complications.

Vaccination time: It takes about two weeks to develop the body's immune system. At this time you may be infected.

Side effects of vaccination: Five to ten percent of the vaccinated can react with fever, muscle pain or a slight discomfort. These symptoms are often harmless and disappear after a short time.

cold: Often, a harmless cold is confused with the flu because the symptoms are similar. However, colds rarely cause complications.

Who should vaccinate?

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

  • People over 60 years old
  • Pregnant women in the second trimester (then the baby is also protected during the first months of life)
  • Preterm infants from the age of six months during the first two flu seasons
  • chronically ill
  • People overweight with a BMI of more than 40
  • Medical personnel and carers, because they have a higher risk of infection. They also have a higher risk of infecting the patients.
  • Residents of nursing homes and nursing homes

Where we talk about health:

Should I vaccinate myself, even if you do not belong to any risk group?

If you get in touch with people at home or at work who have a risk of complications, you should get vaccinated. How to prevent them from infecting such vulnerable people.

In healthier and healthier children, seasonal flu usually has no complications. Your symptoms are awkward. In addition, a vacuum in the fall can be avoided, for example, during winter vacations, flu.

When should not vaccinate?

Those who have had a severe allergic reaction to any of the vaccines in a previous influenza vaccine should not vaccinate. This also applies to people who are very allergic to egg whites.

If you have high fever, you should wait with the vaccine until it is reduced. Otherwise, the protection of the vaccine could be reduced.

In contrast, during pregnancy and lactation, the flu vaccine can be done without a doubt. It is recommended to protect the mother and the newborn from influenza infection.
