title: [Influenza: immunization to new age groups].
abstract: Influenza immunization is a main tool to prevent this important viral illness. Traditional vaccine recommendations, mainly focused to elderly and people with chronic medical conditions, have been expanded during last years. The article summarizes the fundament of lowering the age cut off in adults and of the incorporation of healthy infants between 6 and 24 months. The performance of the vaccine in those new age groups is analyzed. Finally, new groups to possibly be incorporated in future vaccine recommendations are mentioned.
