Technical report: Reduction of the influenza burden in children
Insights
Annual influenza immunization is recommended for high-risk children. Healthy young children, including those 6-23 months old, also face high hospitalization rates and should be considered for vaccination and protected by vaccinating contacts.
Area of Science:
- Pediatrics
- Immunology
- Public Health
Background:
- Children under 24 months, including healthy ones, experience high hospitalization rates for influenza, similar to the elderly.
- Current recommendations prioritize annual influenza immunization for children 6 months and older with high-risk conditions.
- Influenza immunization is not currently recommended for healthy young children.
Purpose of the Study:
- To highlight the significant burden of influenza and its complications in young children.
- To advocate for expanded influenza immunization strategies in children.
- To discuss challenges and recommendations for routine influenza immunization in healthy young children.
Main Methods:
- Review of epidemiologic studies on influenza burden in children.
- Analysis of current influenza immunization recommendations.
- Discussion of factors influencing vaccine uptake and policy implementation.
Main Results:
- Children under 24 months with chronic conditions and healthy children in this age group are hospitalized for influenza at high rates.
- Increased efforts are needed to identify and recall high-risk children for immunization.
- Immunization of children aged 6-23 months and their close contacts is encouraged, with a long-term goal of universal immunization for this age group.
Conclusions:
- Protecting young children from influenza requires a multi-faceted approach, including vaccinating close contacts and caregivers.
- Addressing physician and parent education, vaccine supply, and reimbursement are crucial for implementing routine immunization in healthy young children.
- The ultimate goal is to achieve universal influenza immunization for children aged 6 to 24 months to reduce disease burden.
Abstract:
Epidemiologic studies have shown that children of all ages with certain chronic conditions, such as asthma, and otherwise healthy children younger than 24 months (6 through 23 months) are hospitalized for influenza and its complications at high rates similar to those experienced by the elderly. Annual influenza immunization is already recommended for all children 6 months and older with high-risk conditions. By contrast, influenza immunization has not been recommended for healthy young children. To protect children against the complications of influenza, increased efforts are needed to identify and recall high-risk children. In addition, immunization of children between 6 through 23 months of age and their close contacts is now encouraged to the extent feasible. Children younger than 6 months may be protected by immunization of their household contacts and out-of-home caregivers. The ultimate goal is universal immunization of children 6 to 24 months of age. Issues that need to be addressed before institution of routine immunization of healthy young children include education of physicians and parents about the morbidity caused by influenza, adequate vaccine supply, and appropriate reimbursement of practitioners for influenza immunization. This report contains a summary of the influenza virus, protective immunity, disease burden in children, diagnosis, vaccines, and antiviral agents.
