Families Fighting Flu was established for the children who die each year due to the influenza virus (commonly called "the flu"). The non-profit organization is a group of families and pediatricians who have experienced first-hand what it is like to lose a child to the flu or to have a child experience severe medical complications from the flu. The organization was incorporated in 2005 with the mission of reducing pediatric deaths due to the flu by raising awareness about the importance of getting all children vaccinated against the flu.

Families Fighting Flu, the first organization of its kind, is urging the Centers for Disease Control and Prevention's (CDC) Advisory Committee on Immunization Practices (ACIP) — the group of experts who provide advice and guidance to the CDC on the most effective means to help prevent vaccine-preventable diseases — to recommend annual universal pediatric influenza vaccination to ensure that parents get their children vaccinated against the flu every year. The organization encourages all families and individuals who have either lost a child to the flu or whose child has experienced medical complications from the virus to come forward and join together through this organization for support, flu research and prevention. Losing a child is a parent's worst nightmare, but together, these families and pediatricians can help one another by working toward the important goal of preventing the flu among children.

Providing a meeting place for families and friends, this site is a way for members to realize they are not alone in this fight against influenza. The organization gives them a chance to channel their grief into helping to save others by encouraging annual flu vaccination for all children in the United States.
