Neither. Both are already undead so are not valid targets for each other's abilities to create more of their kind. The vampire is immune to the zombie's disease (assuming it's a zombie variant that can spread zombie-ism) because undead are immune to disease, and the zombie has no CON score to be reduced by the vampire's blood drain.
