Family Members getting the whooping cough vaccine

So, can we have a conversation. Our dr brought up anyone going to be around the baby needs to have their whooping cough vaccine & flu vaccine. Me & my SO proceeded to tell my MIL last week. Fast forward today, she tells us she wont be getting neither one of those vaccines & neither will her son (age 9). That she’s never heard of that, we are crazy & that they just won’t kiss the baby (which they weren’t allowed to kiss our baby regardless me & SO already discussed this) & I feel like it’s my job to protect our daughter & since they won’t get the vaccines they won’t be allowed to see our daughter till she is probably vaccinated.

Am I being to dramatic?? Or Is it my right to say sorry but no? I honestly feel so torn cause she made us feel like we have no other option but to be okay with them not getting vaccinated. & I’m not okay with that. I don’t want anyone who isn’t properly vaccinated around our daughter.
