"Two times in the space of a decade, then, I became the beneficiary of one of the greatest acts of human altruism: living organ donation."

"Now, I find myself dependent on others yet again. This time, my health relies on people to get vaccinated against the coronavirus. As a transplant recipient, I am one of the immunologically unlucky: those who derive insufficient or no protective immunity from vaccinations. We organ recipients take medications — typically anti-metabolites — that suppress our immune systems, specifically, the function of the body’s B cells, which are responsible for generating antibodies. These drugs are necessary to prevent the body from attacking implanted organs, thus blocking organ rejection. But this means that many of us produce no detectable defenses against covid-19."

From "Opinion: Vaccines probably don’t work on me. So I must rely on others to beat covid-19" (WaPo).
