I was just wondering, I have some Eravac in the fridge to protect against RHD. I inject myself, the rabbits I'm intending to inject next week are Mini Rex and a couple tans. The vaccine is currently 1 day before it runs out of date. Will it still be ok to use in a week, and will it still be active? If it helps, it's a 20 dose vial, I do 0.5ml per rabbit, clean needle each time. Also where can you get more?
