Fluenz is a vaccine used to help protect children and adolescents from 2 years to less than 18 years old against seasonal influenza (flu). Seasonal influenza epidemics are mainly caused by two types of influenza virus, known as influenza A and B. Each of these circulate as different subtypes or lineages, which change over time. Fluenz contains live attenuated (weakened) types of the influenza virus; two type A viruses (subtypes A-H1N1 and A-H3N2) and one type B virus (Victoria lineage), which are selected in accordance with the official recommendation for the annual flu season.
