Claim · 1953 · Cellular therapy (Frischzellentherapie)
Cellular therapy as administered at Clinique La Prairie is safe; fresh fetal cells do not provoke meaningful immune rejection in human recipients and present no significant adverse-event risk.
The safety claim was central to the clinic’s positioning during Niehans’s lifetime. Swissmedic and the Swiss Federal Office of Public Health identified substantial risks from fresh-cell therapy, including hypersensitivity, injection-site abscess and sepsis, zoonotic infection, autoimmune disease, and reported deaths. The clinic published no adverse-event registry during Niehans’s career.
