Hello, Anti-Vaccine – These seven answers to the flu vaccine are especially for you.

Today, November 9 is the National Influenza Day. Those who are immunized on this day will benefit from the recommended flat rate benefit of 30 francs. Interested parties may voluntarily use the proposal in one of the doctors' practices or pharmacies participating in the campaign.

Many people do not want to be vaccinated for other reasons. However, highly contagious influenza ("influenza") is often underestimated because it is confused with an under-estimated flu infection ("cold"). The flu can severely weaken the immune system and cause life-threatening complications. Every year 1,500 people die of illness and consequences in Switzerland.

The vaccine does not provide 100% protection against infection, but it is the best treatment for the flu. It is best to take this vaccine before the flu episode begins. It is best to be between mid-October and mid-November. Recommended for those who want to protect themselves and not infect others. If you are in a risk group (see # 5), immunization is urgent.

How effective is the flu shot?

Vaccines can not provide absolute protection because influenza viruses are mutated and the immune system can not always accurately detect and combat this. Efficacy also depends on whether circulating viruses and vaccines contain these viruses. Premiums vary from year to year, but often exceed 90 percent.

Other factors, such as age at vaccination, also affect effectiveness and are low in older people. Therefore, it is not possible to accurately quantify the effectiveness of a vaccine against a particular season. According to the Federal Health Agency (FOPH)
Young adults have a 70-90% risk of illness, around the elderly

However, in spite of the vaccine, in terms of disease,
It got weaker. Serious complications also occur less frequently.

Could the vaccine have side effects?

Yes. About one-third of people who get vaccinated have a redness and some edema or pain at the injection site. They sink within a couple of hours and do not need any treatment.

Nausea Rashes, edema, allergic asthma, or almost all of the already existing allergies have little to do with serious allergic reactions. If you suffer from serious side effects, you should see a doctor.

There is very little inoculation to the antagonist-barre syndrome (GBS). Approximately one million cases of vaccination. However, GBS occurs much more frequently as a result of complications of influenza infection. Therefore, the vaccine protects more from GBS than it does. However, the risk of serious complications from the flu is much higher than the serious side effects of the vaccine.

Can the vaccine cause flu?

No, it's impossible. Vaccines that stimulate the immune system to produce specific antibodies are composed of inactivated virus fragments of various influenza virus strains. It can not cause flu.

Why do people who get vaccinated show symptoms similar to the flu?

There are five reasons.

Insufficient scope: If the vaccine does not fully cover the circulating virus system, it only provides partial protection.

Low protection: In the case of elderly people or immune deficient people, only a weak immune system is formed after vaccination and only partially protected. However, the flu is less likely to cause symptoms and complications.

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

Side effects of vaccination: 5 to 10 percent of people who have been immunized can respond to fever, muscle aches, or some discomfort. These symptoms are usually harmless and disappear after a short time.

cold : Because the symptoms are often similar, a harmless cold is mistaken for a flu. However, the cold rarely causes complications.

Who should be immunized?

People in the risk group should be immunized. The problem is:

  • People over 60 years
  • Second trimester Pregnant woman (the baby is protected during the first month of life)
  • 6 months premature infant during first 2 flu season
  • Chronically ill
  • BMI over 40 overweight
  • Medical staff and caregivers are at high risk of infection and they are also more at risk of infecting patients.
  • Retired and nursing home residents

Do you need immunizations even if you are not in a risk group?

You should get vaccinated if you come into contact with family or work colleagues who are at high risk for complications. How to prevent infecting such vulnerable people.

Seasonal flu in healthy children and healthy young adults usually progresses without complications. Her symptoms are uncomfortable. You can also prevent influenza during the winter vacation by vaccinating in the fall.

When should you not be vaccinated?

People who have had a severe allergic reaction to the vaccine from previous flu shots should not be immunized. This also applies to people with egg whites allergies.

If you have high fever, you should wait until the vaccine has settled down. Otherwise, vaccine protection may be reduced.

Conversely, during pregnancy and lactation, flu vaccines can be made without hesitation. It is a good idea to protect your mother and newborn from flu infections.

Health and nutrition

So cough and sneeze.
