For example bacterial infections were the major cause of death back in the old days but when Ernest Chain infected 2 mice with a very deadly high dose of Streptococcus bacteria then proceeded to inject the subjects with penicillin. The treated subjects survived though the untreated ones died. This lead to further trials of research to test the toxicity of penicillin and development for higher quality penicillin for the consumption of humans. With the test on mice, the outcome was that it revolutionized the capability to treat bacterial infections, which was a major cause of fatalities. Just this simple test on mice lead to the saving of millions of lives for both humans and animals. As you can see animal testing has proven to be very effective over the last century in developing essential necessities and treatments humans need to thrive such as insulin, antibiotics for tuberculosis, cancer treatments, blood transfusions, tamoxifen(cancer treatment) and so many other medicines and treatments that
