OMC - I've done it again!!

I saw this beauty online through Pet Finders. I kept going back and looking at her. I thought I've got 5, one more won't make much of a difference - right? I called about her thinking if she's still up for adoption and I can have her, it was meant to be - Right? So she's in my bathroom right now, scared to death and such a tiny girl. The other guys haven't noticed her yet, but once she calms down she should be OK. She was in a laundry room with 10 - 12 other cats and they were all getting along fine. It should work out. There was a Tortie in with her that was returned because he played in the water bowl and made puddles all around. He was so sweet, I was tempted.

Question - She is due for her vaccines and I have them to give to her. Should I do it now while she is still scared and get all the scary stuff over in one day or wait till she's more comfortable?

Oh, I think I'm going to name her Jeannie. You youngsters won't remember this, but there was a T V show way back called "I Dream of Jeannie" and I immediately thought her eyes looked like Jeannie in the show.
