Medical Testing for Animals :(

I think we want to research new medicines for restrain virus or bacteria and so on, but we must be sacrifice life of animals that I feel not happy.Animals are also live in the world, why we deprive their life,we don't have the lights.Someone could say:"If we don't find animals test that what we should find.''I think researchers have not found to replace it to test,therefore we are just only at the cost of animals.

''White Mouses''are tested by researchers create new medicines or vaccines,who inject these medicines to mouses' body and observe their action.If the tests are successful and these vaccines will be use.

Although the action is not inhuman,I think researchers will research new manners to substitude animals.
