Debating on one vaccine

Hello. My daughter is 5 years old and has had zero vaccines. Auto immune runs in my family. Her doctor has had no problem with declining her vaccines. However there's one thing that bugs me. We live on a farm and I debate on if she should get a tetanus shot. The problem is it is a combination shot. I've thought about this on and off for a long time. I'm not sure what to do. A friend of ours also just had a bunch of young calves die from what their vet thought was possibly tetanus after they were banded (rubber band on their balls to make them fall off and turn them into steers which are boy cows with no balls) my fiance is 43 and he's never had a cow die from being banded. Regardless it has been one I've debated for some time. Thoughts?
