Chimpanzees Once Used for Vaccine Research Get Health Checks as Part of Long-Term Care
Veterinarians are using anesthetic exams, blood tests and X-rays to detect disease early and tailor lifelong care for aging chimps.
- On August 25, 2026, chimpanzees formerly used in research received comprehensive health checks at the Second Chance Chimpanzee Refuge Liberia in Bapakwali, Liberia, offering them medical assessments as they age.
- More than 400 chimpanzees were used in hepatitis B vaccine experiments from the 1970s until early 2000s, with many captured from the wild as infants before spending years in laboratories.
- Examinations included blood and fecal tests, ultrasounds, and mobility checks to assess long-term health. Sanctuary veterinarian Belen Perez Hernando said these vital checks help detect early disease signs.
- Humane World for Animals assumed permanent responsibility for 60 chimpanzees in 2015. Director Liliana Pacheco Ricote said the care offers them "a second chance to live with dignity the life that they deserve."
- West African chimpanzees are classified as critically endangered due to rapidly declining numbers. Liberia holds the second-highest population of these primates in West Africa, trailing only Guinea.
