If I'm not mistaken, one of the translations had one of the dragons say that with the antibodies they had "almost" no chance to turn into a dragon. If this translation is correct and we consider that this is a manga then we can expect the dragonification happening sometime. But I hope not, it wuld feel too convenient if it happens in a crucial moment.
