Chimpanzees once used for vaccine research get health checks as part of long-term care

BUJA (AP): A group of chimpanzees once used in laboratory hepatitis B vaccine experiments has received health checks at their new home in Liberia, in hopes of giving them a second chance at a normal life. The West African chimpanzees received checks ranging from teeth cleaning to X-rays and pedicures at the Humane World for Animals’ Second Chance Chimpanzee Refuge in central Liberia, Liliana Pacheco Ricote, director of the sanctuary, told The Associated Press.
