I am in the COVID-19/transplant research study at the University where I had my transplant done. The head of the study shared with me the solid organ recipients who got Covid-19 and survived had “remarkably robust anti-body production and protection. I remember him telling me that because, after hearing it, I somewhat jokingly asked him if I could get COVID-19 in a protective environment so that they could make sure it doesn’t get too far. Of course, he told me That was the worst idea he had ever heard. So the answer is getting the actual virus produces a huge immune response even in transplant recipients.
