when discussing a vaccine for ECE with my vet, he said it wouldn't help my ferrets because they'd already been exposed. Pam Grant said the same thing in her ECE post this AM. My question is, why not? If ECE came be contracted again - and it is apparent that this is so, wouldn't yearly vaccinations help, and if not, why not? We (humans) are typically revaccinated for certain conditions (tetanus, etc) and animals are re-vaccinated annually for distemper, etc due to decreased antibodies. Wouldn't 'natural' post-exposure antibodies decrease in time as well, and wouldn't a vaccination be helpful to boost antibodies in previously exposed ferrets? Thanks - Debbie Riccio WNYFLFA Rochester, NY P.S: Would a vaccine be helpful to any kits my previously affected jills or exposed jills would have? What if just the hob had had ECE and not the jill - could kits get ECE thru sperm or semen? Or just via the jill if she gets ECE from semen? Can the jill get ECE from semen of a previously exposed hob? [Posted in FML issue 1250]
