@hello1234 I would think it would be helpful to test for antibodies. My transplant was almost 5 years ago. My transplant team would not write a lab order for the antibody test but my PCP did and I do have antibodies which is somewhat reassuring. I think it would definitely be helpful to determine if the vaccine that was given prior to transplant has been affected by the immunosuppressants. My gut feeling is that the antibodies remain strong. I think that because we are not advised to get repeat vaccinations for other things that we may have had prior to transplant.
