@diana61 I had seen that video also and something else made me think a J&J would be a good option but my transplant team said to try to get the same for a booster and if that was not available to get the other of the two-dose vaccines. I had Pfizer for all three shots.

I am wondering too how much which immunosuppressant you are on affects the antibody result. I am a liver transplant patient but take sirolimus due to tacrolimus causing kidney problems. My transplant team would not order a lab test for antibodies so my PCP did. I think I will ask her to do that again.
