@alaking, Welcome to Mayo Clinic Connect. Thank you for posting this question. I am a transplant recipient, and I do not have any experience with the medication Belatacept from my own experience to share with you. On Mayo Connect, patients share their experiences with others who are like them, and I look forward to hearing from somneone who has had an experience related to this medication.
In the meantime, @alaking, I would like to learn a little more about your situation so that I might try to find someone to connect you with. Have your doctors mentioned this medication? Are you being considered for a 2nd transplant? What organ(s) are involved?
