Why is this year's flu so severe?

Why is this year's flu packing such a wallop? And why is it taking such a harsh toll on young children?

One reason is that the flu virus has changed, or mutated, slightly in the nine months since flu makers designed this year's vaccine, and those changes may be rendering the vaccine less effective, according to flu expert John Treanor, M.D., director of the Vaccine Treatment and Evaluation Unit at the University of Rochester. Treanor provides an update on this year's flu and explains the reasons for its unusual severity in an article in the January 15, 2004 issue of the New England Journal of Medicine.

While this year's flu vaccine may be less effective than expected, an additional problem is making this flu season worse for young children. The flu virus most prevalent this year is from a family of viruses that has been scarce in the United States over the last three years. That means nearly all children ages three and under have never encountered the virus or one similar to it and haven't produced antibodies that can fight it.

"The immune systems of young kids are being caught off guard this year," says Treanor. "Young children who get influenza are at higher risk for becoming seriously ill and developing other complications. That's why we're hearing more reports of very sick infants and toddlers, and why we have been urging parents to have their kids immunized." Treanor notes that the Centers for Disease Control and Prevention recently began to recommend influenza vaccination for all children six months to 23 months of age.

Flu vaccines typically are designed to protect against several strains of virus from different families of influenza. But over time viruses change, or mutate. Scientists studying this year's flu virus have discovered two particular changes that are troublesome because they occurred in proteins on the outer surface of the virus that this year's vaccine was designed to target.
