Certainly over time science has had to do things which are not good to get benefits for the human being. Which is very sad because they hurt some people to save others which is not fair but it has been this that has achieved the advances that we have today. Currently it is not allowed the experimentation in the human being without consent. Which is good because before they did in many people without their prior authorization. So it seems fair to me that they have suspended this study because they are breaking the law and the principles of bioethics. I loved this article very useful in my area. Greetings friend.
