George Franklin III is one of the longest-surviving kidney transplant recipients in the U.S. Now 67, he received his lifesaving surgery 46 years ago, which has enabled him to lead a healthy and active life—swimming, bowling, visiting friends and even competing in a sporting tournament known as the International Transplant Games. But since the beginning of the COVID pandemic, he hasn’t been able to do any of these things. Like most transplant recipients, Franklin, who lives in western Maryland, has to take medication to suppress his immune system and prevent his body from rejecting the donor organ. In March 2021 he received the Johnson & Johnson COVID vaccine but did not develop detectable levels of antibodies. “Those of us that have no antibodies,” he says, “it’s as if we’ve never taken a shot.” (In November 2021 he got the Moderna vaccine and finally developed antibodies.)
