Nosferatu and variant vampires

[Calliope5431]

What do people like about Nosferatu and vrykolakas vampires lore wise? Have you used them? How do you make them fit into your setting?

I really love the idea, but have never used them before in a setting. So I'm curious to hear your stories!

My first thought reading this, "did you sneeze? Bless you."

But to be honest I have no idea what's different about those vampires. But I suspect they can easily just replace PF2E vampires.
