OK, I'm a bit confused now about the reasons vaccine reactions occur.  I
had thought that reactions were caused by the ferret's allergic reaction to
a vaccine, and that the allergy would make itself known the first or second
time the ferret was vaccinated.  But the things that have been written just
recently sound more like vaccine reactions are due to particular batches of
vaccine, and so there'd be no way of predicting when reactions might occur
during a ferret's vaccination history.  Does anybody have any comment on
this?
