I remember hearing something about a ferret's blood vessels contracting during a vaccine reaction, and about possible health complications later. Has anyone ever heard of negative health effects that a ferret suffered related to an earlier vaccine reaction? Basically I'm wondering if a ferret has a bad reaction and then pulls through, will he/she be have sustained any bodily damage that will put their health at a greater risk in the future. I know that's not worded well, but hopefully the question behind my mumbling is clear. Thanks Risa [Posted in FML issue 4116]
