Are you against or for using animals for medical research?

Nowadays, there are a lot of countries that use animals for meical research; however, there are some negative and some positive arguments about this.

One of the arguments for using animals for medical research is that every year there are more than one milion animals that die in laboratories because of medical research; they can't hold the experiment, it isn't fais. In addition, although animals and people are similar in a lot of aspects, there are also a lot of differences between us.

On the other hand, if we use animals for medical research, we don't need a person, as it is easier to kill one animal than a person; also we have a lot of similar aspects, this is a great advantage because we can advance more in medical research.

All in all, I'm not in favour of using animals for medical research: neverthless, I recognize it is easier to kill an animal than a person.
