What is the difference between the Salk and Sabin polio vaccines?
In the developing world, however, outbreaks of poliovirus still occur sporadically, an ironic consequence of the polio vaccine itself. The polio vaccine comes in two types: the Salk vaccine, made with a killed virus and the Sabin vaccine, made with a live but weakened, or attenuated, virus.
Which vaccine is Sabin or Salk vaccine?
The success of an inactivated (killed) polio vaccine, developed by Jonas Salk, was announced in 1955. Another attenuated live oral polio vaccine was developed by Albert Sabin and came into commercial use in 1961. Polio vaccine is on the World Health Organization’s List of Essential Medicines.
Why did Sabin vaccine replaced Salk?
Between 1963 and 1999, Sabin live vaccine largely replaced Salk killed vaccine everywhere in the world. However, because the live virus in the vaccine occasionally became strong enough to cause actual disease, Salk killed-type vaccine has replaced the live type in the United States.
What is Sabin polio vaccine?
oral poliovirus vaccine (OPV), or Sabin vaccine, named for its inventor, Albert Sabin. IPV, based on killed, or inactivated, poliovirus serotypes 1, 2, and 3, was the first vaccine to break the scourge of polio epidemics in the 1950s.
Did Salk patent 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….

What do you mean by Salk and Sabin?
In the 1950s Salk and Sabin developed separate vaccines—one from killed virus and the other from live virus—to combat the dreaded disease polio. Jonas Salk became a national hero when he allayed the fear of polio with his vaccine, approved in 1955.
Is polio vaccine made from monkeys?
Inactivated poliovirus vaccine (IPV) and live oral poliovirus vaccines (OPV) were prepared in primary cell cultures derived from rhesus monkey kidneys. Studies of these vaccines led to the discovery of a new virus called SV40 in 1959.
How long did Salk work on the polio vaccine?
Salk worked incessantly for two-and-a-half years. Salk’s inactivated polio vaccine came into use in 1955.
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.

What was unique about Jonas Salk’s polio vaccine?
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.
