Vaccines may not be as effective for those who are immuno-compromised. Protecting them needs to be made a top priority, says researchers — to keep them safe and to slow the emergence of variants.
The COVID vaccines haven't proved very effective for people living with organ transplants. But getting a third dose of the mRNA vaccines gave a big bump in antibody levels in a new study.
For most people, COVID-19 vaccines promise a return to something akin to normal life. But for the hundreds of thousands of Americans who have a transplanted organ, it's a different story.
An international team has put human cells into monkey embryos in hopes of finding new ways to produce organs for transplantation. But some ethicists still worry about how such research could go wrong.
Health officials are changing how they assess the regional nonprofits that find organs to transplant. The goal is to understand, and eventually fix, the geographic disparities in organ availability.
After Tom Saputo underwent a double-lung transplant in 2018, he was stunned by the more than $11,000 bill for his share of a 27-mile air ambulance ride from one hospital to another.
The nation's organ transplant network is considering changing how livers are distributed. The goal is to make the system fairer, but critics worry patients in poorer rural areas could lose out.
When Dr. Vanessa Grubbs fell in love with a man whose kidneys were failing, he'd been waiting for a transplant for years. Her book explores the ways racial inequity is embedded in the system.
Results from two sets of experiments provide encouragement to researchers working on "chimera" embryos that may someday be used to grow organs for transplantation into people.
A cardiologist knows how to game the system to get his patients bumped up the list for a heart transplant by giving them care they don't need. Is that being a good doctor — or a moral failure?
At least one U.S. hospital is attempting uterine transplants for women born without a uterus, or who've lost it to disease. The surgery has yielded births in other nations, but poses real risks, too.
Researchers experimenting with chimeric embryos say they could develop into adult pigs, sheep or cows with human organs that one day might be suitable for transplantation in people.
Scientists have tried for years to grow artificial kidneys in the lab. They've gotten a bit closer by using stem cells to create an "organoid" much like a fetal kidney. But it's missing key parts.
