Young blood transfusion refers to transfusing blood specifically from a young person into an older one with the intention of creating a medicinal benefit. The scientific community currently views the practice as little more than snake oil.
Research
Research was done on rodents at Stanford University in which blood transfused from young mice seemed to invigorate older mice; the circulatory systems of the mice were connected which put them in a state of parabiosis. Another study at UC Berkeley found that blood from older mice hurt younger mice, with older mice gaining no benefits from blood from younger mice. One problem with the generalizability of parabiosis experiments is that it is unclear whether the benefits come from the blood that is shared or the older mouse using the younger mouse's organs to purify their blood.
In experiments like this, researchers found that some of these mice died quickly (11 out of 69 in one experiment) for reasons the scientists could not explain, but described as possibly some form of rejection. A researcher who coauthored several mouse studies into young blood transfusion, Amy Wagers, has said that her papers do not provide a scientific basis for some of the existing human trials.
Evidence from two large studies in 2017 showed that the transfusion of blood from younger donors to older people led to outcomes that were either no different from, or led to worse outcomes than, blood from older donors. Research on blood transfusion outcomes has been complicated by the lack of careful characterization of the transfusion products that have been used in clinical trials; studies had focused on how storage methods and duration might affect blood, but not on the differences among lots of blood themselves.
Commercial development
Ambrosia
A startup company, Ambrosia, has been selling "young blood transfusions" for $8,000 since 2017 under the guise of running a clinical trial, to see if such transfusions lead to changes in the blood of recipients. As of August 2017, they had 600 patients. The clinical trial has no control arm so is not randomized and is not blinded. The company was started by Jesse Karmazin, a medical school graduate without a license to practice medicine. David Wright is the licensed doctor overseeing the clinical trial; in his practice he gives intravenous treatments of vitamins and antibiotics for "non traditional" purposes, and was disciplined by the California Medical Board for the latter in 2015. A bioethicist from McGill suggests that Ambrosia is running this trial as they would be unable to get FDA approval to sell this treatment otherwise.
Alkahest
Another company, Alkahest, was started based on the Stanford rodent studies, and as of 2017 was collaborating with European pharmaceutical company, Grifols, to create a blood plasma-based experimental biologic drug which they propose to test on people with Alzheimer's.
