Over the years, many vaccines and medicines have been established due to animal testing. In the 1930s, anesthesia was developed through dogs. Today, many doctors use anesthesia to fix a toothache or to perform a heart transplant. People do not feel pain during medical actions as a result. In the 1940s, treatment for arthritis were studied in rabbits and monkeys and were eventually made. During the early 1900s, polio vaccines were created through experiments on monkeys and rodents (Hayhurst 3). Vaccines have been made for tetanus, rabies, whooping cough, tuberculosis, measles and mumps. With the vaccines, many lives will be spared.a·sy·lum a·sy·lum
Animal testing is used for safety trials. Safety trials are important because they ensure that all vaccines and drugs are safe enough to release to the public. As a result of safety trials, the lifespan of a human has also increased. In the early 1900s, Dr. Simon Brimhall became the first laboratory animal veterinarian. When Brimhall began his work, the average lifespan of adults in the United States was
about forty seven years (Cothran 2). In the years following, the lifespan increased almost sixty percent which means adults can live up to seventy five years. Animal research has enabled for a longer...
