I know of no data, either anecdotal or comprehensive that supports 
these conclusions.  There was a recent report from Canada that showed 
a possible/likely vaccine reaction from a booster dose (see promed 
for details), but that is the only thoroughly reported negative 
reaction to my knowledge.  So far, 1000's of doses have been 
administered to zoo animals with almost no reports to the National 
Zoo WNV surveillance system, or any of the zoo vet list serves.

However, this issue has yet to be seriously studied so we have no 
hard data to back this up.  I still see nothing that resembles a 
higher than normal vaccine reaction risk with this product to date.
