CDC Ends Primate Research Opening the Door to Life Outside a Lab for Macaques

The Centers for Disease Control and Prevention is ending all research that uses monkeys. The CDC’s decision brings an end to its primate program, leaving the agency’s colony in limbo. The group includes about 200 macaques, many of whom have known only a life in the laboratory. CDC researchers were told the shutdown must be finished by the end of the year.

Macaques in CDC programs have historically been used in studies on HIV, hepatitis, and other infectious diseases, undergoing frequent blood testing, infection trials, periods of restraint, and extended time in rooms with limited enrichment.

The CDC has not formally stated where the monkeys will go or how they will be supported once the research ends. Setting primates up for life outside a lab usually takes researchers and caregivers who know how to work with them, veterinarians who understand their health needs, and space where the animals can act naturally and form social bonds again.

The Primate Rescue Center explains how primates rescued from research labs, the pet trade, or the animal entertainment industry often have medical or behavioral issues that require time and care to address.

The Physicians Committee for Responsible Medicine has urged the CDC to partner with accredited sanctuaries for placement.
