trentonlarkin- Who Invented The Polio Vaccine? The two best known persons are Dr. Jonas Salk and Dr. Albert Sabin. There were a succession of findings by many scientists which led to an ultimate polio vaccine. But it was a scientist by the name of Dr Jonas Salk who, with the help of his colleagues at University of Pittsburgh Medical School, discovered the polio vaccine itself. Dr Jonas Salk was the son of Orthodox Polish-Jewish immigrants and was born in New York in 1914. He dedicated his life to researching the causes, prevention and cure of diseases such as influenza (flu), polio and towards the end of his life, cancer and AIDS. He was also a published author.
However there are other notable scientists who were either directly or indirectly involved with the discovery of the polio vaccine. Perhaps the most notable were Harvard’s Johns Enders and his team, who collectively discovered how to grow polio in test tubes a few years before the polio vaccine was discovered. In fact it was Enders who, in 1954, shared the only Nobel Prize given for polio research.
Another notable scientist was Dr Albert Sabin. Shortly after Dr Jonas Salk, Sabin announced a variation polio vaccine, this time using “killed” viruses.
When was the polio vaccine discovered? The polio vaccine was made pubic in April, 1955. Drawing from previous findings of other scientists, Dr Jonas Salk discovered a vaccine which effectively created a mild infection with the polio virus without running the risk of infecting the patient. When the polio vaccine was discovered , it couldn’t have happened at a better time. More and more outbreaks had been occurring since the turn of the century. In 1952 alone, the CDC estimated that there were over 21,000 paralytic cases of polio in the USA. The public was becoming increasingly frightened of the ominous poliomyelitis virus (otherwise known as infantile paralysis), which was crippling, paralyzing and even killing people.
Dr Jonas Salk’s vaccine put a stop to the polio epidemic. He never patented his polio vaccine discovery and distributed the polio vaccine freely. Nowadays, most people in developed countries never develop polio.Source(s): a medical professional

The first was developed by Jonas Salk and first tested in 1952. Announced to the world by Salk on April 12, 1955, it consists of an injected dose of inactivated (dead) poliovirus. An oral vaccine was developed by Albert Sabin using attenuated poliovirus. Human trials of Sabin's vaccine began in 1957 and it was licensed in 1962. Because there is no long term carrier state for poliovirus in immunocompetent individuals, polioviruses have no non-primate reservoir in nature, and survival of the virus in the environment for an extended period of time appears to be remote. Therefore, interruption of person-to person transmission of the virus by vaccination is the critical step in global polio eradication. The two vaccines have eradicated polio from most countries in the world, and reduced the worldwide incidence from an estimated 350,000 cases in 1988 to 1,652 cases in 2007.Source(s): College history books
