You may want to do some research on the 'cytokine storm' which is what this particular influenza produces.
You are correct, it is not the influenza itself that causes the damage, it is the immune system in 'overdrive' which produces cytokine in excess
amounts destroying cellular integrity and making one especially susceptible to pneumonia and other such complications.
The reason the very young and old are not as severely affected (presumably) is because the stronger your immune system is, the more damage it will do
to you once you've been infected.
If I'm wrong, I invite correction.
