Thanks for asking. What country, province, or state are you in? I am not sure where if the world you are and thus not sure of which species of vulture you are referring to. Vultures may be large and dark, but they are not known to be a danger to humans. If you gave me more information about the species and what more specifically is your concern? Once you know what species of vulture is in your neighborhood you could find out more about their life history and the benefits they provide to the local ecosystem and food web. You could then help educate your neighbor of their positive attributes and help them overcome any fear they may have of vultures that could be perhaps attributed to them based on their large size or dark color? By eating things such as carrion of dead farm animals, roadkill, mice, and shrews they help recycle the nutrients of these animals and spread nutrients needed to renew life.  If you have a landfill or compost facility, they might be found there eating garbage or rotten food. They is beneficial for soil conservation as they are taking food nutrients that were tossed out and processing them and then fertilizing the soil, fields, natural areas etc.  with needed nutrients. This is one-way nutrients are recycled or replenished.
