VHd and the combined vaccine????

[bunnylover177]

coco was a 6 year old bun who has always been vaccinated and 9 months ago had the combined vaccination. he died suddenly and when the vet opened him up he had enormous multiple cysts on his liver. he sent it all off to azoology path lab and the results came back as biliary cyst melanoma leading to acute liver failure typical of VHD. I Know last year there was a bid debate about the efficacy of the combined vacc especially for rabbits previously vaccinated for VHd. Does anyone know how that debate end? Was there thought to be a problem? Coco,s companion had modular maxi a few years ago but she is ok now. Could Coco have had nodular maxi at some point and his immune response to the combined vaccine was the problem? struggling for some answers.....

Goodness :?

On the vaccine data sheet it says this:

Rabbits that have been vaccinated previously with another myxomatosis vaccine, or that have experienced natural myxomatosis infection in the field, may not develop a proper immune response against rabbit haemorrhagic disease following vaccination.

I had my vet on the phone so I,m a bit clearer. Coco had two problems. He had biliary cysts which, had we known about them , could have been removed but he also sub acute hemeretic hepatitis (excuse my spelling). That could be caused by a massive sudden infection, something toxic he ate or, and this is interesting, chronic VHd. - the same idea as nodular maxi only with VHd so his body fought the VHd as he was vaccinated but was overwhelmed. he died under anesthetic when he was being x rayed so i guess his little body had just had enough. The lab couldn't,t do further tests as his tissues would need to have been frozen. The good news is that none of this is infectious so our other buns are safe. my vet does not think it was a problem with the vaccine.

As far as I know the new vaccine only has a possibility of lesser coverage for VHD if the european myxi vaccine had been used previously, not the UK version.

It sounds as though Coco was just desperately unlucky I am really sorry
