Kidney transplant recipients are still at high risk of severe disease due to the coronavirus even after being fully vaccinated, disease experts have warned.

“What we’re telling patients right now is, unfortunately, they’re going to have to take extra precautions of continuing to do all the things that we had to do early on, which is to wear masks, social distance, wash hands, because there’s very little protection [against COVID-19],” said Mike Spigler, vice president of patient services at the American Kidney Fund.
