Bloodsuckers (2005) on Netflix

Plot summary

Humanity has spread into space by 2210 and met alien races, among them the vampiric Leatherfaces and the Vorhees. Vampire Sanitation crews go ahead of settlement, sweeping planets clean of the predators. The Heironymous is one such ship, captained by Nicholas Churchill, who loves the work. His new first officer, Damian Underwood, was blacklisted by Star Fleet after a mission that killed his crew, and he wants a transfer. Telepath Quintana, born to two humans who were vampirized, tracks vampires for the crew, though Rosa Wong and Roman Kuchinsky question where her loyalty lies. Across the galaxy the vampires, led by Muco, have no wish to live peaceably with humans; they intend to rule.
