Yea normally I'd do the combined one first then RHD2 two weeks later... But how things currently are... I'd do RHD2 then the combined one two weeks later personallyI think with the current situation going on, its advised to get filivac if you can, and do that one first. it covers both RHD1 & RHD2 if I'm not mistaken. both RHD viruses are airborne, so there's nothing we can to against it to protect. myxi is mostly flies I believe, so steps can be taken to prevent it. although of course both are as important.
eravac is a different vaccine and only covers RHD2. its usually given to meat rabbits as it has a withdrawal period of 0 days, meaning that there is no wait time between having the vaccine and when the rabbit can be slaughtered. if you can only get that one, then I'm not sure what I would do first, possibly still eravac, but its a tough call.
don't quote me on it, but I do believe that eravac has only 9 months of immunity (filivac has 12), or at least that's what this link says:
