Flu shot / dtap shot while pregnant help

First let me start off by saying my mother in law can be the devil and doesn’t know when to stop talking,

anyways I mentioned I will be getting the flu shot next week and the dtap (tdap??) shot also and she lost it saying that I shouldn’t do that that I should really talk to her daughter who is also pregnant and a nurse and all this shit and then finished off by saying it will give my baby autism.

I can’t stand her and I just need some none biased advice on if I should get the flu shot or not without getting worried and anxious for my unborn child.

Thanks in advance 💕
