Pig Kidney Keeps US Man Alive 271 Days
Pig Kidney Keeps US Man Alive 271 Days
The News
A New Hampshire man with end-stage kidney disease lived 271 days with a genetically modified pig kidney — a world record for an animal organ in a human body — before receiving a kidney from a human donor.
Tim Andrews, a shop manager, was 66 when he received the pig kidney in January 2025, according to The Independent.
The transplant allowed him to stop dialysis, The Sun reported. Andrews told the Daily Mail that 18 months on he is "healthier than I ever thought I could be."
Timeline
Andrews, then 66 and suffering from end-stage kidney disease, receives a genetically modified pig kidney.
He comes off dialysis and lives with the animal organ while waiting for a human donor.
The pig kidney's run ends, the longest an animal organ has functioned in a human body, per the BBC.
Andrews receives a kidney from a human donor.
The case is reported by the BBC, The Independent, the Daily Mail and The Sun.
Reactions
Andrews framed the result as a personal turnaround, telling the Daily Mail he is the first person in the world to have survived a pig kidney transplant and is healthier now than he expected to be.
Coverage treats the nine-month mark as the central claim. The BBC asked directly whether the case points to "the future of organ transplants."
What's Next
The obvious question the case raises is how long a gene-edited animal organ can be made to last, and whether it can serve as a bridge for patients stuck on dialysis while they wait for a human donor. The sources reporting Andrews' case do not lay out a timetable for wider use.
More
Reported details vary slightly between outlets: the Daily Mail gives Andrews' current age as 67, The Sun as 68. All four sources agree on the core facts — a pig kidney, nine months, a human transplant afterward.
