Hello. The Vetala have been in only one episode unfortunately. We don't have much information about them. Currently there is no known cure for them. I think these species cannot be cured because they do not turn humans into their kind. Their lineage exists on breeding among each other. We thought that there were no cure for werewolves until last season but apparently there was. Anything is possible. However, if you want a logical sort of explanation for curing monsters, check angels. Castiel was able to cure Dean who was turning into a Jefferson Starship.
