Which statement is true about animal research contributions?

• A. It has not contributed to medicine
• B. It only contributes to vaccines
• C. It is not used in teaching
• D. It has contributed to medicines, drugs and understanding host-pathogen interactions

Answer: (D)

Animal research has contributed broadly to medicine and our understanding of infections, not just vaccines. Research in animal models has helped discover and develop medicines and therapies, supported safety and efficacy testing for new drugs, and deepened our knowledge of how hosts respond to pathogens and how infections progress. For example, canine studies played a role in the development of insulin therapy, and animal work has been essential in understanding immune responses and guiding vaccine design. It is also a foundational part of teaching in medical and veterinary training, where students learn physiology, pathology, and experimental methods using animal models. So the statement that captures these wide-ranging contributions—medicines, drugs, and understanding host-pathogen interactions—is true.
