From NetFlix:

Earth’s population is up against a vicious plague that’s transforming everyone into vampires and draining the world of an increasingly precious resource: blood. As the human race count nears zero, could science hold the key to a solution?

Do you remember Ethan Hawke in Gattaca? Here also he stars in an intelligent, better than average sci-fi plus vampire theme film. However this particular film is very violent, or (to make a bad pun) should I say very bloody. As the villain in the plot Sam Neill again plays a smarmy, soft-spoken and unscrupulous blood merchant.

Be warned, some scenes are ugly: humans are farmed for their blood; bodies tend to explode in the sun; blood-starved vampires feed on humans; the fun never stops.

Toward the end of the film the plot confused me a bit. Even the Wikipedia article is a little vague about the final scene with the soldiers.

No, this is not an adult film. But for those of us who love trash, it could be entertaining.
