Interesting article: The researchers, led by Yoshihiro Kawaoka of the University of Wisconsin at Madison, stress that the experiment is only conclusive for lab mice, not humans. Nevertheless, they say, it adds strongly to suspicions that what made the type A 1918 virus strain so extraordinarily vicious was the unique profile of its HA gene. .... The strain was especially lethal for healthy young adults...The reason for this is unclear. One theory is that the immune system reacts differently at various stages of life, and that young people may have been particularly vulnerable to an uncontrolled response by cytokines, the proteins that play a big role in causing inflammation.
