I'll talk about the advantages and
disadvantages of scientific tests
on animals. I think this can help to discover and cure new diseases, but always using it well.
Tests scientific can help to discover
new vaccine to
unfamiliar diseases. There are many laboratories are investigating animal a vaccine for
cancer. These tests can certainly kill some animals,
but it may save
many lives.
In all laboratories when they discover a new
vaccine, don´t know the effects it can have, and tested
on animals, such as rats. Scientists can see the effects of the vaccine and if no bad results
can be used by sick patients.
For end, my opinion is
that it is okay to try the tests on animals,
although some may
die, but it can cure diseases, but in tests
they do, they have to make them better for the least possible
harm to the animals.
