Contrary to the era’s prevailing scientific opinion, Salk believed his vaccine, composed of “killed” polio virus, could immunize without risk of infecting the patient. Salk administered the vaccine to volunteers who had not had polio, including himself, his lab scientist, his wife and their children.

Jonas Salk, in full Jonas Edward Salk, (born October 28, 1914, New York, New York, U.S.—died June 23, 1995, La Jolla, California), American physician and medical researcher who developed the first safe and effective vaccine for polio.

Since 1988, more than 18 million people can walk today who would otherwise have been paralyzed, and 1.5 million childhood deaths have been averted thanks to the polio vaccine. Four regions of the world are certified polio free—the Americas, Europe, South East Asia and the Western Pacific.

The man who created the first polio vaccine. Today marks the 100th birthday of Dr Jonas Salk, the medical researcher and virologist responsible for creating the world’s first polio vaccine. In the United States, where Salk was based, an epidemic in 1952 had killed over 3000 people and left more than 21,000 paralysed.

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.

Some European countries imported the Salk IPV from the US whereas some other like the Netherlands, Denmark, and Sweden started production of Salk IPV in their own public health production units [9]….

Almost all children (99 out of 100) who get all the recommended doses of polio vaccine will be protected from polio. The first polio vaccine was available in the United States in 1955. Thanks to widespread use of polio vaccine, the United States has been polio-free since 1979.

The smallpox vaccine was the first vaccine to be developed against a contagious disease. In 1796, the British doctor Edward Jenner demonstrated that an infection with the relatively mild cowpox virus conferred immunity against the deadly smallpox virus.

Vaccinations began in the 18th century with the work of Edward Jenner and the smallpox vaccine.

Currently, 16 vaccines – some requiring multiple doses at specific ages and times – are recommended from birth to 18 years old. Recommended vaccines include: Influenza (annual flu shot) Diphtheria, tetanus and pertussis (DTaP)

These six are the target diseases of WHO’s Expanded Programme on Immuni- zation (EPI), and of UNICEF’s Univer- sal Childhood Immunization (UCI); measles, poliomyelitis, diphtheria, pertussis (whooping cough), tetanus and tuberculosis.

Five out of six World Health Organization regions are now certified wild poliovirus free—the African Region, the Americas, Europe, South East Asia and the Western Pacific. Without our polio eradication efforts, more than 18 million people who are currently healthy would have been paralyzed by the virus.
