I don't want to get jumped on here, but I have been thinking long and hard about the vacc's in particular the myxi jab, and I probably wont be letting them have it anymore. As far as I am aware it doesn't stop them getting myxi, just gives them a better chance of surviving it. I would not put my rabbits through fighting the illness, and having to be given medication and being handled. I think for my rabbits it would be a lot kinder to have them pts straight away if they were to get myxi, which hopefully they never will.
I think for a lot of people the vacc is a very good idea, if they have tamer rabbits, who don't get so stressed at being handled they stop eating, with confident owners who are able to give the medication when required without stressing the rabbit even more. My rabbits wouldn't cope with it all, and I wouldn't put them through it.
I'll still do the VHD jab though.
Oh and about the cleaning, mine have their trays emptied and washed with lemon juice twice a week, usually thursday and sunday.
