I think the only possibly meaningful results of this poll would be the worringly large number of vaccinated rabbits who seem be be developing myxi. Which I guess we can put down to natural mutation of the virus, although it would be worth feeding this info back to the manufacturers. I think it is also worth noting that the relatively low number of unvaccinated rabbits developing myxi as noted in the poll so far is probably more likely to be due to the fact that most of the people on here vaccinate their buns therefore, there are less unvaccinated bunnies to get sick.
Also, from a purely scientific point of view I'd be interested to know whether the development of nodular myxi is as a result of vaccinated/wild rabbits being more resistent and thus expressing a less virulent form of the disease or whether, as in some other infectious diseases, this newer form of myxi has evolved as a way of allowing the virus to circulate in it's host population without completely burning it out.
