What kind of vampirism are you trying to keep under control? And in what manner do you want it to be controlled?
The best solution is just to keep them fed. If they crave murder, feed them murder. However, it should be noted that vampires already do this themselves, they will fulfill their craving eventually, and this will exacerbate their antagonism to society (or their ecosystem). Their desire is often self-destructive and compulsive, and even the smarter ones are often led to constant suffering by their own vampirism. If you want to prevent this from happening, to keep this destructive vampirism under control, you should design a system where the vampire can feed without causing harm. A system where they can kill without killing. For example, if a blood vampire craves fresh human blood, you can probably be a donor, or advice them to find someone close to them who can accept and understand their cravings. Sometimes they might not even understand their own impulses because they have never been given the time to contemplate it, and the object of their craving might not even be blood, and something more fundamental, which can be the case, but sometimes not. If it really is the case, you might be able to find a substitute for blood that can lead to less antagonism, or design a system that can nourish their craving more wholly.
You're an outsider, and you will probably be able to notice different things about their vampirism, but it's best that you pay attention to their internal perception and experience which they've lived with their entire lives. An outsider and an insider perspective will be very vital to a solution and a complete reconciliation cannot ignore either. You'll have to work out a solution together, but I'm sure you can do it.
If the pacification of the vampiric impulses are done, that's half of your job done, but it's not done yet. They say you have to teach a man how to fish and you'll feed them for a lifetime, same thing with vampires; if you want to reintegrate them into society by themselves, they will have to have greater self-knowledge and the knowhow of vampirism as well. However, if they fundamentally cannot do this themselves, you should not shame them, because many vampires actually can't do this, and that's okay. It is fine for vampires to be reliant on the help of others, and it's fine to feed a man a fish forever, not everyone's supposed to be a fisherman. However, there is always a potential for them to grow, and if they wish to do so, and I'm sure they eventually will, you should encourage them, they will be happier that way!
Usually for self-knowledge to blossom and fully settle in, it's vital that they have a clear head so that they can think about themselves and contemplate many many difficult things. That's why the first step is so important, placating vampirism is crucial for them to be able to make better judgments, and it allows them to feel more whole with their own goodness. It's shadow work, to an aspect of themselves that have caused so much suffering to them and their surroundings throughout their entire life, so it will often not be easy. Sometimes they'll either fall into "the world is good i am terrible" mindset or "i am good the world is terrible" mindset, they might go and suppress their cravings, understanding that it has done so much harm, but that will often not go well, and can often lead to destructive outbursts and an aftermath that will lead to a heavy and seemingly inescapable despair. Your job, for their development, is to always challenge their understanding without denying their attempts to grow. If they fail to find a solution and fall into despair, you should be there to lift them back up and tell them "Good job, you've worked hard" and tell them that it is often necessary to fall before they can learn to walk, and that they can rest before they wish to try again, and assure them that even if it is a step back, it is still progress. You'll have to always believe in them, and their potential.
One day, some of them will be able to run faster than you do, and develop better systems of placating better than yours. If that is the case, then your job is done. I hope that answers the question on the individual level on a general way.
Of course, this won't be the end of the road if what you mean is vampirism *entirely*, which is also very important. But I've learned that it's best to not bite off more than you can chew, and you should focus on what you can do best. As long as there is the condition that enables vampirism, there will be vampires.
The problem on the individual level is often caused by the collective, and the problem in the collective can be caused by the individual. If there is a solution to the entire condition of vampirism, it will have to look at all levels. I have no answer on how to keep vampirism as a whole in check, maybe not yet, maybe someone else will come up with it, but I'm sure one day, there will be one. We'll just have to be patient.
