It's possible (I think).
But, if you are only 2 days into your CK experience, it might be something to store for a week (or three

)
If I were you, I would do the big Tutorial on the wiki http://www.creationkit.com/Category:Tutorials
... but, to be fair, that only has bits and pieces on character creation (and next to nothing on advanced character creation). But, that said, it will teach you lots and lots about Quests, packages, scripting and so forth (all of which you will need for your vampire follower)
You might also take a look at a vampire in the CK. If you right-click on a vamp actor (in the object list, left side of screen) you should see a Use-Info option. Clicking that will show you all of the quests and such like that the character is involved in ... You could then start crawling through how it all works (but you will probably need a better understanding of CK/Papyrus before much of it makes sense)
It takes a few days to start getting comfortable with how it all hangs together ... Once you are over that hurdle it gets
easier
