The polio vaccine was tested on animals, and it reduced the global occurrence of the disease from 350,000 cases in 1988 to 223 cases in 2012. Animal testing is a controversial topic that’s sometimes overlooked and helps people and saves many lives. Living systems of human beings and animals are very complex, therefore not all of the calculations may work out. Studying cells in a petri dish doesn’t give the chance to study related processes occurring in the central nervous system, endocrine system, and immune system. Animals are similar to humans in many ways,therefore it is the best option to take without losing a human life.Chimpanzees have 99% of the DNA humans have and mice genes are 98% similar to humans.

If vaccines weren’t tested on animals, millions of animals would have died from many different diseases including rabies, tetanus, etcetera. Animal testing has been instrumental in saving species from extinction, such as the black-footed ferret, and the California condor. Koalas are being ravaged by the STD chlamydia and are now being tested with new chlamydia vaccines that may stall the animal's disappearance. A majority of biologists and many of the largest biomedical and health organizations in the U.S. endorse animal testing. A 2011 poll of 1,000 biomedical scientists conducted by the science journal Nature found that over 90% agreed that the use of animal testing in research is essential. The American Cancer Society, American Physiological Society, and many others advocate the use of animal testing in scientific research. Animals are very different anatomically,metabolically,and cellularly from human beings and therefore make poor test subjects. The anatomic, metabolic, and cellular differences between animals and people make animals poor models for human beings. Animal testing is thought to be cruel and inhumane for the animals. According to Humane Society International, animals are commonly subjected to force feeding, forced inhalation, food and water deprivation, and many other horrible
