Liberia Chimapanzees Sanctuary | Nation & World

Chimpanzees once used in hepatitis B vaccine experiments are getting health checks at their new home in Liberia. The West African chimpanzees receive care such as teeth cleanings and X-rays at the Second Chance Chimpanzee Refuge. American researchers used more than 400 chimps from the 1970s until the early 2000s. Liberia has the second-highest number of chimpanzees in West Africa. The checks assess long-term health and tailor care plans. The sanctuary’s veterinarian says these checks are vital for the chimps’ well-being. The impact of the experiments on the chimps is still being assessed.
