Animal experiments go through a process designed to make sure that an experiment is carried out only after all the alternatives have been considered. The experiments go through and receive the necessary approvals from institutional committees made up of scientists, an expert veterinarian responsible for animal welfare, a lawyer, a researcher from the humanities and a public representative.
It is important to emphasize that science, as a human activity, is built and advances through competition and constant mutual review by peers who are experts in specialized fields of research. Peer review has proven very effective in advancing science, and we are confident that this mechanism is highly effective and also ensures animal welfare.
