How can I ensure my baby doesn’t get vaccinated? OB vs midwife?

I told my OB that I don’t want my baby to be vaccinated and she told me she was okay with it although she recommended it. I’m really against having my baby vaccinated. I’m afraid the nurses won’t listen to me, that they’ll take the baby out of the room to do it. Do you think I’m better off switching to a midwife and birthing center? I’m a FTM and I might want to have the epidural so I’m not sure I can get it with a midwife?
