It's a matter of resources. Animal testing has found hundreds of vaccines against HIV that work in primates, but none of them have worked in humans. How is that a useful thing to spend time on? You have a model, and it's proven that your model doesn't work: I would expect you to throw away the model. You could spend those excellent researchers and science budget on anything else, and expect better results. (I get that all drugs have been tested on animals out of legislative requirement, but I hope it's clear we are talking about using animal models for de novo drug discovery). For a business-oriented forum, I find it hard to understand why people see this as valuable.
