I am off prednisolone for 4 months and on MMF for 6 months. I have also had splenectomy 10 years ago. I am going to celebrate Christmas with a family with kids who are having or just had chicken pox. I had chicken pox 20 years ago in my early teens. But I'm a bit concerned now as I was immunosuppressed recently - is my immune system wiped out now and I could get it again? And if so, how dangerous it would be for me?
