I think the difference between a Zombie and a Vampire really depends on what the main Vampire does to them? As far as I can tell, if Dio absorbs their blood or some other method, they turn into Zombies, or just flat out die. However, the stone masks created Vampries in a way such that the spikes would puncture certain parts of the brain to activate their full potential.

Dio probably had the ability to do this as demonstrated by his parasite bud things that control people in part 3. I think the main reason he did not turn people into vampires in part 1 was due to his pride and carefulness. If there was another vampire, he obviously wouldn't be the strongest being,  and the only reason he made some in part 3 was proubably due to the fact that even if he made them, he still had an upper hand due to having the The World.
