There are leukemia vaccines being developed, which seems odd because vaccines are for viruses. It is possible the word "vaccine" is being used for some reason other than accuracy. But the question must be asked, why a vaccine for an unknown cause? They do the same with MS. But don't say such and such virus causes it. Something is being kept from us because science isn't only property and profitable, its evidence in lawsuits too.
