This work is not in ferrets and it is preliminary, but it appears that
in at least one species the "common wisdom" that the immune system
weakens with age may simply be wrong. Instead, inappropriate immune
responses may be more common.

I just wanted to put this here because posts are so very often written
as if a weakened immune system with age is to be automatically assumed,
AND because I can imagine a mechanism where this could play into the
increase of cases of anaphylactic shock at older ages compared to
younger (besides there being more exposures), and because of the hefty
titer levels our own older ferrets had when their CDV titer levels were
done.
