Is there a console command to infect my character with vampirism? Thank you in advance.

In order to totally compatible with potential mods, the simplest way to do it is to just add the disease

Player.AddSpell 3DB3D

and then wait three days. You could artificially speed things up by using

set Vampire.daycount to 3

which will cause you to become a vampire the next time you rest.

Thank you.
