I haven't got my baby vaccinated yet at 2 months

I've heard bad things about vaccinations and am worried about getting them. I want to research it first. My doctor didn't tell me anything about them at her 2 month visit but I need a new doc, one that explains things and spends time at the visits to make sure she's healthy. I asked about the Hepb shot and whether it's transmitted by bodily fluids. If that's the case why would she need it? That's like getting an AIDS shot.

Please be nice with your responses, I'm a first time mom and just worry about everything I do for her. And I know people can be mean on here when someone isn't knowledgeable.
