Collins insists that investigation with non-human primates has been and "still is vital to help us understand and improve human health". However, the ethical approaches are questioned by more and more people every time.
The issue gets even more polemic when stories like Foxie's reach the media. Foxie was a chimpanzee that had to be rescued from a lab. They experimented on her with hepatitis vaccines. Not only was her health affected, but also her mental stability –for she was also forced to breed babies that were taken away from her. With the help of wildlife keepers, loads of patience, and dozens of dolls that make her feel like a mom again, Foxie is rehabbing from her past as a lab primate.
In the last two years all procedures that used these species have been carefully reviewed, and a strong conclusion has been reached: all of them can be carried out in alternative ways –or using other species (a "solution" that would keep the polemic on).
Famous ecologist and primatologist Jane Goodall, who has been fighting for animal rights (and especially for primates rights) for over 50 years, believes this is a big step for the US. "I've been working on this since 1987, and it's finally happening. It's come about in stages, and this is the final one, where the last 50 chimpanzees that were in the hands of scientists have been freed".
