edit doesn't work

so it's mainly just K171 and K180 .
Why does the mouse (and human ?) immune system concentrate on Sa,
just coincidence or (unknown) chemical "attractors"

---edit1---
...checking... but almost all H1, including seasonal and mexflu has 171K and 180K .. I'm confused

is the US-age structure of mexflu different from other countries ? I'm not aware of that.
Only USA had the 1976vax

Great post ! It should receive wide circulation. This casts an entirely new light on the much-maligned 1976 Swine Flu vaccination effort, which now appears to have had a mitigating or protective effect against novel 2009 H1N1. It may not be enough to turn around entrenched anti-vaccine sentiments, but the successes of the current and past H1N1 vaccines ought to be incorporated into public health communications going forward.

Correct, they did not look at 1945-1957 H1N1 vintages. They did
observe that the 1944 vintage protected mice less well than earlier
ones, implying antigenic drift by that time. Epi studies have
suggested that those born after 1944 do not have cross-reacting
antibodies. See for example
http://www.eurosurveillance.org/ViewArticle.asp.... I
think it would have been useful for the authors to include some
1945-57 H1 viruses, but I would not count on infection with those
providing protection.

Dr. R, I didn't see in the above a test for H1N1 virus of the 1943-1957 vintage. Did I miss that? If not, then it may be speculative to state that one would have to be born on or before 1943. Since H1N1 of the 1918 type continued to circulate until it was displaced by the pandemic H2N2, some protection may still be afforded by those that may have been exposed or innoculated, although other epitopes may have been involved. Right?
