Do you believe that experimentation on animals for scientific purposes is justified. Are there any alternatives to animal experiments?

The generation of safety data is fundamental for the development of new medicines and vaccines. Before testing the new medicine or vaccine, it is a global standard established by many regulatory authorities that tests with

animals

should be conducted to understand the safety profile of the medicine, which are named pre-clinical tests. The pre-clinical tests with

In the 1950s, it was found that a lot of babies were born without arms and legs due to the use of medicine for nausea during their intrauterine development. It would be avoided if pre-clinical research with pregnant mice were conducted before launching it on the market for pregnant women to use. Never mind, alternatives for animal experimentation should be continuously developed in order to decrease as much as possible the use of

in preclinical studies. Until new technologies and methods are developed, it is important to keep all efforts on the conduction of preclinical research with a focus on
