RHDV2 killed thousands of rabbits last year and it's still lurking in the environment. We vaccinated close to 400 rabbits and they all need booster shots this year and we're expecting to house another 400 rabbits or more in our new sanctuary. We need to order at least that amount of vaccine or more now as there will only be one order this year. Even using bulk packs of vaccine, this is going to be an expensive proposition. Vaccinating the rabbits is crucial. Please help!
