we know the typical shape of an influenza-wave.
Why does it go down and not stay at the peak ?
Must be because people develope immunity and the
virus runs out of native victims.
But this immunity doesn't last so long, because
the next season the same happens again.
There are several types of immunity.
The vaccine apparantly addresses another
immunity, which lasts longer. I assume the wave-immunity
only lasts ~4 months, then the next wave may come.
And then we have this immunity which lasts
life-long and somehow protects against
old strains, but not entirely, since we may still
get it each season...
I'd like a graph, how the different sorts
of immunity expire over time. Where is it ?
