There have been several media reports of healthy, immunized children dying. Although the flu does tend to kill older people and younger with underlying conditions, I think that the recent deaths of children with no underlying conditions are unusual (and several have been immunized with current vaccine).
I tend to believe the info in the pro-med article.
A number of deaths in children and infants aged under 14 years) and young adults have been reported to be associated with influenza infections. At least 12 of the deaths in children (in England and Scotland) have been shown to be due to influenza A infection, (7 confirmed as A H3 viruses, 5 of which have been confirmed to be of the Fujian strain). The increased general practitioner consultation rates for influenza-like illness in children may reflect increased susceptibility in younger age groups. A high proportion of children may be immunologically naive because of low levels of influenza activity in recent years. If this interpretation is correct, many children who are becoming sick are experiencing their primary influenza illness, and it is to be expected that some will become ill enough to require hospital care and some, unfortunately, will die. The risk of severe illness is increased, but not confined to those with underlying chronic illnesses. The A H3N2 subtype of influenza is usually associated with higher morbidity and mortality in all age groups than the other circulating types or subtypes of influenza.
