Are you for or against using animals for medical research?

At the moment, it is that it's a reality nowadays, scientifics use animals to taste some products, or some cures that it would be efficient to many people in the future. This should be forbidden, at least in this country. One of the arguments for the practice with animals it is because if you try with them scientifics do not kill people in the case that the cure ins't effective. When you try these things with animals you may kill them but maybe it's better to kill an animal and not a person. On the other hand, I think that this isn't good at all, because animals don't have to die for these things that are going to be good things for humans, but not to animals. Scientifics might try products like shampoo with other things, but not killing animals like rabbits when they taste on it. All in all I am not in favour of this, but I reckon that if you don't taste things in animals you aren't going to know the reactions that these products are going to have in humans. I couldn't change this but I would like to invent another way to taste these things without killing innocent animals.
