Chimpanzees go into retirement as US ends animal testing

From laboratory to sanctuary, we meet the chimpanzees getting a new lease on life.

The United States was the last major nation to perform invasive testing on chimpanzees, infecting them with HIV, tuberculosis and other diseases.

It stopped in 2015 because of animal cruelty concerns. Now, instead of living out their days in a lab, the chimps have gone into retirement in a new home.
