Overview of Influenza

Influenza is a contagious respiratory illness caused by influenza viruses, which can cause mild to severe symptoms, leading to hospitalization or death. There are two types of influenza viruses (A and B) that cause seasonal outbreaks each year, otherwise known as the influenza season. Children younger than 5 years old, especially those younger than 2, and children and adolescents with certain underlying medical conditions are at a high risk of developing serious influenza-related complications. Influenza vaccines are a safe and effective way to prevent serious symptoms, hospitalization, and death due to influenza-related illnesses.

AAP Recommendations

The American Academy of Pediatrics recommends annual influenza immunization of all children without medical contraindications, starting at 6 months of age. Any licensed influenza vaccine (injection and intranasal) appropriate by age and health status can be used for vaccination.
