Democrats said this was a conspiracy and those who talked about it needed to be censored for China.
YES, it was.
A breakthrough occurred in 1949, when poliovirus was successfully cultivated in human tissue by John Enders, Thomas Weller and Frederick Robbins at Boston Children’s Hospital. Their pioneering work was recognized with the 1954 Nobel Prize.
Not long afterwards, in the early 1950s, the first successful vaccine was created by US physician Jonas Salk. Salk tested his experimental killed-virus vaccine on himself and his family in 1953, and a year later on 1.6 million children in Canada, Finland and the USA.
The results were announced on 12 April 1955, and Salk’s inactivated polio vaccine (IPV) was licensed on the same day. By 1957, annual cases dropped from 58 000 to 5600, and by 1961, only 161 cases remained.
Salk had a family of THREE.
Then he decided to test it on 1.6 million people?
I have no clue as to why you want to fight about the development of the Polio vaccine vs the Covid vaccine and how long it took to development them You must be fun to live with.
Now for the FACTS!
"Salk, born in New York City in 1914, first conducted research on viruses in the 1930s when he was a medical student at New York University, and during World War II helped develop flu vaccines. In 1947, he became head of a research laboratory at the University of Pittsburgh and in 1948 was awarded a grant to study the polio virus and develop a possible vaccine.
By 1950, he had an early version of his polio vaccine."
"Salk’s procedure, first attempted unsuccessfully by American Maurice Brodie in the 1930s, was to kill several strains of the virus and then inject the benign viruses into a healthy person’s bloodstream. The person’s immune system would then create antibodies designed to resist future exposure to poliomyelitis.
Salk conducted the first human trials on former polio patients and on himself and his family, and by 1953 was ready to announce his findings. This occurred on the CBS national radio network on the evening of March 25 and two days later in an article published in the
Journal of the American Medical Association. Dr. Salk became an immediate celebrity."
"
In 1954, clinical trials using the Salk vaccine and a placebo began on 1.3 million American schoolchildren. In April 1955, it was announced that the vaccine was effective and safe, and a nationwide inoculation campaign began. Shortly thereafter, tragedy struck in the Western and mid-Western United States, when more than
200,000 people were injected with a defective vaccine manufactured at Cutter Laboratories of Berkeley, California. Thousands of polio cases were reported, 200 children were left paralyzed and 10 died."
"The incident delayed production of the vaccine, but new polio cases dropped to under 6,000 in 1957, the first year after the vaccine was widely available. In 1962, an oral vaccine developed by Polish-American researcher Albert Sabin became available, greatly facilitating the distribution of the polio vaccine. Today, there is
no year-round transmission of poliovirus in the United States. Among other honors, Jonas Salk was awarded the Presidential Medal of Freedom in 1977. He died in La Jolla,
California, in 1995."
