Need help with events lab

[shadowplaguehelpplz]

Currently I'm making a new scenario that features the shadow plague.

What I can't seem to figure out is how to create a trait that will instantly create a vampire with just one death.

Essentially, I need it so that spores will erupt and infect a few individuals in a random country (I already know how to get spores to erupt using the events lab) before instantly killing them and creating a new vampire immediately.

Would somebody please give me a step by step guide of how to do this?
