Flu Vaccination for Children: Why It Matters During the Back-to-School Season

The return to school increases close contact among children, facilitating the transmission of respiratory viruses. Current recommendations support annual influenza vaccination for children aged 6 months and older who do not have contraindications to vaccination.

Influenza is more than a common cold. It can cause fever, cough, myalgia and significant fatigue, and some children develop complications requiring medical care or hospitalization.

Influenza vaccines are updated seasonally to reflect the viruses expected to circulate. Vaccination reduces the risk of influenza and its potentially serious consequences, although it cannot prevent every infection.

When should children receive the flu vaccine?

Seasonal vaccination is ideally administered before influenza becomes widely established in the community. Approximately two weeks are required for an adequate immune response to develop following vaccination.

Some children aged 6 months through 8 years require two vaccine doses during the same season, administered at least four weeks apart, depending on their previous influenza vaccination history.

The appropriate vaccine formulation depends on the child’s age, medical history and relevant contraindications. For this reason, influenza vaccination should follow current age-specific and clinical recommendations.
