Eastern Equine Encephalitis

["Karen J. Zelinsky" <kjz2@juno.com>]

Duh-- sounds to me, a dumb outsider, that that horse reacted to the
vaccine -- a "not dead - though-supposed-to-be-dead" virus affected that
"one horse in a million".  Logic.  How many other animals/people get a
mild or serious case of the condition that's supposedly guarded against
by vaccine injection?  And why were those horses vaccininated against a
virus that supposedly never appeared out "there"??

I know horses that have reacted extremely badly to injections.  
All I can think is where the heck is a bit of logic these days??  Of
course I am assuming that the horses had been vaccinated BEFORE the poor
show horse BECAME ill????
