This may sound irrational ...

[*Ash*]

My understanding from reading another thread is that your niece died within 24 hours of a vacc. Is that correct? I don't know how old she was though.

I can see why you are fearful. The death of a child is a horror too painful to contemplate. It is tragic that your sister has experienced it. I think it is easy to experience fear during pregnancy.It doesn't matter how many other babies we have had. Are you fearful that your daughter may die at the same age that Kassidy was? Or that she will die if she is vacc. (not ncecessarily at the same age)?
I hope you don't mind me asking, but I am trying to gain a better understanding of your fears. It is apparent that these fears have played on your mind for months and it must be emotionally exhausting for you. Has it affected your ability to enjoy your pregnancy?

It doesn't matter how many times someone may tell you that a fear is irrational, it feels real and valid for the person experiencing it. I don't know how to make your fear dissipate. Do you feel that there is a certain milestone that you need to reach, for example, your daughter being older than Kassidy was when she died?
