Health checks have been performed on a group of chimpanzees that were previously used for hepatitis B vaccine experiments. The checks included procedures such as teeth cleaning, X-rays, and pedicures. These chimpanzees are receiving long-term care at a refuge.

The refuge is providing a second chance at a normal life for the chimpanzees. Many of the chimpanzees were captured in the wild as infants and used in experiments from the 1970s until the early 2000s.

Further details about the care and history of the chimpanzees are available from the source, including information about the refuge where they are being cared for, located in Liberia.
