Did Jonas Salk make money off the polio vaccine?
Salk was immediately hailed as a “miracle worker” when the vaccine’s success was first made public in April 1955, and chose to not patent the vaccine or seek any profit from it in order to maximize its global distribution….

Why was oral polio vaccine discontinued?
Use of the oral polio vaccine was discontinued in the UK in 2004 and the US in 2000, and the UN agency advises that the use of the oral vaccine should be discontinued after polio is judged to be eradicated because of the risk of vaccine-derived outbreaks.
What was the problem with the oral polio vaccine?
A major concern about OPV is its ability to revert to a form that can cause paralysis. Outbreaks of vaccine-associated paralytic poliomyelitis (VAPP) have been reported in many countries of the world [2, 4].
What were the side effects of the Salk vaccine?
Common side effects include:
- redness, pain, swelling, or a lump where the shot was given;
- low fever;
- joint pain, body aches;
- drowsiness, mild fussiness or crying; or.
- vomiting.
When did Jonas Salk start working on the 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.
How did Jonas Salk create the 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.
When did they quit giving the polio vaccine?
The oral poliovirus vaccine (OPV) is a weakened live vaccine that is still used in many parts of the world, but hasn’t been used in the United States since 2000. Using IPV eliminates the small risk of developing polio after receiving the live oral polio vaccine.
Can you still get polio if vaccinated?
No, the inactivated polio vaccine (IPV) cannot cause paralytic polio because it contains killed virus only.
When did they stop giving oral polio vaccine?
OPV was recommended for use in the United States for almost 40 years, from 1963 until 2000. The results have been miraculous: Polio was eliminated from the United States in 1979 and from the Western Hemisphere in 1991. Since 2000, only IPV is recommended to prevent polio in the United States.
Why did IPV replace oral live vaccine?
At least one dose of IPV must be introduced, given in addition to OPV, to protect against type 2 poliovirus and to boost population immunity. The switch from tOPV to bOPV will reduce the risk of vaccine associated polio and increase protection from types 1 and 3 polioviruses.
How long did it take to eliminate polio?
Thanks to the polio vaccine, dedicated health care professionals, and parents who vaccinate their children on schedule, polio has been eliminated in this country for more than 30 years. This means that there is no year-round transmission of poliovirus in the United States.
Is oral polio vaccine safe?
OPV is safe, effective and is the essential tool available to protect all children against polio. It has no common side effects and has been used all over the world to protect children against polio. Over the last 20 years, this vaccine has saved 5 million people from permanent paralysis by polio.
