Hello, vaccine opponents – 7 flu responses are special for you

Daniel Huber / watson.ch

Many people do not want to be vaccinated – for various reasons. However, highly contagious influenza ("flu") is often underestimated because you like to confuse them with a significantly harmless flu infection ("cold"). Inflammation weakens the immune system and can cause life threatening.

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 flu episode begins – preferably between mid-October and mid-November. It is recommended to those who want to protect themselves and do not want to infect others. If you belong to a risk group (see section 5), vaccination is urgently needed.

How effective is flu?

The vaccine can not provide absolute protection because influenza viruses change so that the immune system can not always reliably detect and fight. Efficacy also depends on which viruses are circulating and whether the vaccine will cover them. Coverage ranges from year to year but often exceeds 90 percent.

In addition, other factors such as the age of the vaccine affect effectiveness – it is lower in the elderly. Therefore, the effectiveness of a vaccine for a given season can not be accurately determined – according to the Federal Office of Public Health (FOPH) it is reduced to healthy
Younger adults are at risk of disease by 70-90 percent, in the older ones
30-50 percent.

However, if it is a disease regardless of the vaccine, the symptoms are often
impaired. In addition, severe complications appear less frequently.

Can the vaccine have side effects?

That. In about one-third of the vaccinated persons, redness and mild swelling or injection site pain appear. They take a few hours to two days and do not require treatment.

Nausea, rash, edema, allergic asthma or – usually allergies already present – are rarely associated with a severe allergic reaction. If you suffer from severe side effects, you should see a doctor.

Guillain-Barré syndrome (GBS) is extremely rare – in one case up to one million vaccinated. However, GBS occurs much more frequently as a result of complications of flu infection. The vaccine protects more than GBS than it does. In any case, the risk that the flu causes serious complications is much greater than the serious side effects of the vaccine.

Can the vaccine cause flu?

No, that's not possible. A vaccine that stimulates the immune system to produce specific antibodies is composed of fragments of inactivated viruses from various strains of influenza virus. You can not cause flu.

Why do vaccinated people sometimes have symptoms of a similar flu?

Five reasons can lead to:

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

Low protection: In the elderly or immunocompromised persons, only the immune system of the weak body appears after vaccination and they were only partially protected. However, if they get a 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 point you can be infected.

Side effects of vaccination: Five to ten percent of the vaccinated can respond to fever, muscle aches, or weakness. These symptoms are usually harmless and disappear after a short time.

cold: Often harmless cold is wrong for the flu because the symptoms are similar. However, the cold rarely causes complications.

Who should be vaccinated?

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

  • People over 60
  • Pregnant women from the second trimester (then the baby is also protected during the first months of life)
  • Prenatal babies with an age of six months during the first two flu
  • chronic ill
  • overweight people with BMI over 40 years
  • medical staff and carers because they have an increased risk of infection. They also have a higher risk of a patient's infection.
  • Residents of retirees and nursing homes

Where are we already talking about health:

Should I be vaccinated, even though you are not a member of a risk group?

If you come into contact with people at home or at work who have an increased risk of complications, you should be vaccinated. How To Prevent Infection Of Such Vulnerable Persons

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

When should I not be vaccinated?

Do not vaccinate those who have had a severe allergic reaction to any of the previous flu vaccines. This also applies to people who are allergic to egg whites.

If you have a high temperature, you should wait until the vaccine is reduced. Otherwise, vaccine protection can be reduced.

Conversely, during pregnancy and lactation the flu vaccine can be done without hesitation. It is recommended to protect the mother and the infant from influenza infection.
