What is an alternative?
By any common-sense definition, the word 'alternative' suggests a choice between two or
more options. In the case of animal experiments there is no choice. If a non-animal (in
vitro) method is developed to replace animals, then it must be used.
Advances in science and technology can lead to techniques that can replace animals.
However, different research methods are generally complementary rather than alternatives.
For instance, there is much interest in the technique of human microdosing, and antivivisection groups see this as a way of replacing animals in safety testing. But by its very nature, microdosing cannot predict toxicity or side effects that occur at higher 'therapeutic' doses, and it is clear that animal studies will still be required to asssess toxicity prior to human trials.
Few in vitro techniques at present can directly replace the use of animals.
