Die Vampirschwestern

The current (15th of August, 2018) IMDB description is absolutely wrong. The show doesn't have a character named Anastasia who's trying to save her sister from dying after drinking the blood of a dead person.

It's about two half-vampire/half-human sisters who move with their parents, a vampire father and human mother, out of Transilvania to their mother's hometown in Germany. There, they attempt to live among the humans and keep it a secret that they're vampires. The two sisters try to deal with and adjust to normal human preteen/teenage life.

I loved the movie, as said.
