Animal testing is flawed basically because the human and animals’ systems are totally different, which is a scientific problem that cannot be fixed. The most noteworthy example is thalidomide which was used as a sedative and prescribed to treat morning sickness in pregnant women in the 1950s. Before it was put to use, thalidomide already passed the animal tests successfully. However, unfortunately, over 10,000 children had birth defects after mothers-to-be used it. Even primate animals which are similar to humans fail to anticipate what would happen in humans. For instance,when scientists test the therapeutic antibody (anti-CD28 monoclonal antibody TGN1412) did not realize that there existed a fatal immune response that was triggered in humans.
