The poor contribution of chimpanzee experiments to biomedical progress

Area of Science:

• Biomedical Research
• Animal Welfare
• Bioethics

Background:

• Biomedical research involving captive chimpanzees is costly and raises ethical concerns.
• Advocates claim significant advancements in biomedical knowledge result from these studies.

Purpose of the Study:

• To evaluate the actual contribution of chimpanzee experiments to biomedical knowledge.
• To assess the citation rates and impact of chimpanzee research on human disease treatments.

Main Methods:

• A random selection of 95 chimpanzee experiments published between 1995 and 2004 were analyzed.
• Citation analysis was performed to determine the impact of these experiments on subsequent research.
• Examination of cited papers was conducted to identify the contribution of chimpanzee studies to human disease methods.

Main Results:

• Nearly half (49.5%) of the selected chimpanzee experiments were never cited.
• Only 14.7% were cited by papers describing human disease methods, with no essential contribution from chimpanzee studies.
• In vitro, human clinical, epidemiological, molecular, and genomic studies were the primary drivers of medical advancements.

Conclusions:

• Chimpanzee experimentation yields minimal biomedical advancements and incurs significant animal welfare and ethical costs.
• The current ethics committee system appears to have failed in approving many of these studies.
• A ban on remaining chimpanzee experimentation, particularly in the United States, is warranted due to lack of benefit and high costs.
