Vaccination Against COVID 'Does Not Mean Immunity' For People With Organ Transplants

Laura Burns was thrilled when she got her second dose of the COVID-19 vaccine three months ago. The 71-year-old thought that with vaccination, she might finally be closer to being able to see her family in Europe again.

"I have not seen them now for two years, and that's including my stepdaughter. It's very very ... that's hard," says Burns, who lives in Austin, Texas.

But when researchers at Johns Hopkins analyzed her blood, they couldn't detect any antibodies to the coronavirus. "I had no response whatsoever," she says. So she asked the doctors, " 'Does this mean I have no protection?' And the answer I got was, 'It means you may have no protection. You should operate on that assumption.' "
