Vaccinated around the unvaccinated

I'm due to have my baby in early September, I have already gotten my TDAP and flu vaccines. I know the TDAP will offer her some immunity, but it's not 100% right? I'm asking because my boyfriend's family really is excited but there are a few anti vaxx nut jobs in the mix and personally I don't want them around the baby at all. Am I over reacting or should it be fine?
