Transplant: No or Few Antibodies after COVID Vaccination

@hello1234 My transplant department will not write a lab order for an antibody test but my PCP did for me last spring so I am hoping she will again. At that time I did have some antibodies - 13.83 was my measurement.

I am wondering if the immunosuppressant a person is on affects this and also if the level of immunosuppressant that you take does. I take sirolimus and my transplant department monitors my lab work every other month keeping my sirolimus level very close to the minimum level in the range. It would make sense to me that if a person is at a higher point on the range they would not get as many antibodies as a person on the lower end so I am hoping I will have acquired more.

Hi @contentandwell 🙂 I agree with you. Were you originally on Tacronlimis and switched to sirolimus for a reason...or always on sirolimus?

Hey JK. The John Hopkins team has said that there is a direct inverse correlation between antibodies developing if a person had the Pfizer vaccine, is on Mycophenolate, is older, and more recent transplant recipient. So, I had Pfizer, am on Mycophenolate, 62, and just one year out….I figure I’m in the not very hopeful antibody development crowd.
