I'm currently in the process of creating a modpack for 1.16.5 with Vampirism as one of it's many mods. It's a post apocalyptic sort of mod, taking place during a zombie apocalypse. As the title suggests, I desire a feature that allows different mobs, aside from just vampires to be capable of infecting players with the affliction, in this case, zombies and husks. I also second that there should be an option to enable hunger in vampires, as I don't want mine to strictly rely on blood for survival. A sort of more... realistic(ish) approach to Vampirism, and making catching the affliction easier, which can either be beneficial or detrimental, depending on what kind of playthrough a player desires.

Nevermind, found a mod that does this for me.
