The animals that are used for such experimental purposes are euthanized after the completion of the experiment, by the laboratory authorities. It is estimated that roughly 500 million animals die in the process of testing every year, around the world.

These vaccines are tested over animals for years, before they are introduced for human consumption. Similarly advancements in organ transplantation from other species to human beings had been possible only due to such experimentations. There are various other beneficiary areas like genetics research, toxicology testing, biomedical research, and behavioral
