silverwoman, I have a friend with one lung, transplanted several years ago, who is currently going through rejection testing and all that goes with it. No definitive answer yet, but he should know something in a day or so. This is such a tough spot, impossible decision at this time. There is so much still to learn about these vaccines and your situation is truly special. You are going to have to keep yourself safe until you get the absolute YES from your doctors. This is one issue re the covid vaccines that must be dealt with as the true experts......I consider the Mayo infections disease and transplant fellows the experts....have enough time and information to have solid answers. Blessings in this tough time. Elizabeth
