- The MMR vaccine was discovered by Maurice Hilleman in the late  1960s at the pharmaceutical company Merck and Co., Inc. In his  lifetime he created 36 vaccinations for diffe…rent things. He is  credited with saving more lives than any other scientist in the  20th century.

- Polio. Before Jonas Salk began testing a polio vaccine in 1952, an average of between 13,000 and 20,000 polio cases of paralytic poliomyelitis were reported yearly (In fact in 1952, the number of polio cases nationally peaked at 58,000).lthough the broad use of the oral live virus Sabin vaccine resulted in rare but serious cases of vaccine-induced paralytic polio until the late 1990s, new guidelines call for administering four doses of the inactivated Salk vaccine from 2 months to 4 to 6 years, eliminating the risk of vaccine-related polio.

Jonas Salk Jonas Edward Salk (/sɔːlk/; October 28, 1914 – June 23, 1995) was an American medical researcher and virologist. He discovered and developed one of the first successful polio vaccines. Born in New York City, he attended New York University School of Medicine, later choosing to do medical research instead of becoming a practicing physician.

Polio vaccine The Salk vaccine, or inactivated poliovirus vaccine (IPV), is based on three wild, virulent reference strains, Mahoney (type 1 poliovirus), MEF-1 (type 2 poliovirus), and Saukett (type 3 poliovirus), grown in a type of monkey kidney tissue culture (Vero cell line), which are then inactivated with formalin.ral polio vaccines were developed by several groups, one of which was led by Albert Sabin. Other groups, led by Hilary Koprowski and H.R. Cox, developed their own attenuated vaccine strains. In 1958, the National Institutes of Health created a special committee on live polio vaccines.

Polio vaccine Two polio vaccines are used throughout the world to provide immunity to the virus that causes poliomyelitis (or polio). The first was developed by Jonas Salk through the use of HeLa cells and first tested in 1952.ral polio vaccine (OPV) is an attenuated vaccine, produced by the passage of the virus through non-human cells at a sub-physiological temperature, which produces spontaneous mutations in the viral genome.

Poliomyelitis Poliomyelitis, often called polio or infantile paralysis, is an infectious disease caused by the poliovirus.Approximately 90% to 95% of infections cause no symptoms.oliomyelitis has existed for thousands of years, with depictions of the disease in ancient art. The disease was first recognized as a distinct condition by Michael Underwood in 1789 and the virus that causes it was first identified in 1908 by Karl Landsteiner.

Did the polio vaccine eradicate polio? Inactivated Polio Vaccine (IPV) can prevent polio. A 1916 polio epidemic in the United States killed 6,000 people and paralyzed 27,000 more. In the early 1950's there were mor … e than 25,000 cases of polio reported each year.Polio vaccination was begun in 1955.t marked the launch of the Global Polio Eradication Initiative, spearheaded by WHO, Rotary International, the US Centers for Disease Control and Prevention (CDC) and the United Nations Children's Fund (UNICEF).

The Free Sleepydust 'ME/CFS & FMS' Ezine Get Your Free Copy Below Well like many medical breakthroughs, 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.owever 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.

- The impact was dramatic: In 1955 there were 28,985 cases of polio; in 1956, 14,647; in 1957, 5,894. By 1959, 90 other countries used Salk's vaccine. Another researcher, Albert Sabin, didn't think Salk's killed-virus vaccine was strong enough.

- This and the fact that cases of polio caused by the oral polio vaccine (OPV) are not being reflected as polio have ensured that India is now declared “polio free” and is being showcased as a success story of the Global Polio Eradication Initiative that was launched in 1988 by the World Health Assembly.rom 1923 to 1953,before the Salk killed-virus vaccine was introduced, the polio death rate in the United States and England had already declined on its own by 47 percent and 55 percent, respectively.

Jonas Salk When news of the vaccine's success was made public on April 12, 1955, Salk was hailed as a miracle worker and the day almost became a national holiday.

Louis Pasteur Vaccine Discovery. Pasteur’s first vaccine discovery was in 1879 with a contagious disease called chicken-cholera. After unexpectedly exposing chickens to the weakened form of a disease, he proved that they became immune to the actual virus.ouis Pasteur helped resolve the mysteries of several deadly diseases like chicken cholera, anthrax, rabies and silkworm diseases.

Jonas Salk Biography Polio Vaccine In 1947, Salk took a position at University of Pittsburgh, where he began conducting research on polio, also known as infantile paralysis. By 1951, Salk had determined that there were three distinct types of polio viruses and was able to develop a killed virus vaccine for the disease. The vaccine used polio viruses that had been grown in a laboratory and then destroyed. Preliminary testing of the polio vaccine began in 1952 - the shot given mostly to children. National testing expanded over the next two years, making it one of the largest clinical trials in medical history. Roughly 1.8 million children were given the vaccine during the test phase.
