The flu (influenza) vaccine is a vaccine that is renewed every year against the seasonal influenza virus. Because the virus changes frequently, it is repeated every season. Whether or not it is given is decided by the doctor after evaluating the child's age, any additional illnesses and the family's situation.

When it is given

The flu season usually begins in autumn. So that the vaccine's protection lasts throughout the season, it is preferably given before the season starts. It can also be given after the season has begun.

Who it is primarily considered for

  • Children with asthma or chronic lung disease
  • Children with heart disease, diabetes or kidney disease
  • Children whose immune system is suppressed
  • Children in crowded environments and those attending nursery
  • Children living in the same household as someone at risk

This list is not a requirement; these are the points the doctor takes into account during the evaluation.

Side effects

The most common are redness and tenderness at the injection site. Mild fever and fatigue lasting a day or two may occur. These are expected signs of the immune response.

A common misconception

The flu vaccine does not cause the flu. The cold-like picture that appears in the days after vaccination is usually due to another respiratory virus circulating at the same time.
