Jonas Salk in 1955.
Jonas Salk developed the first polio vaccine in 1952.
In the 1950s, Salk developed the first polio vaccine, an injection. In 1962, Sabin developed the oral polio vaccine, taken by mouth, and still used, at present.
1950's The first polio vaccine, called the Salk vaccine, was developed by Jonas Salk and became available in 1955. In 1962 the Sabin or oral vaccine developed by Albert Sabin became available.
Jonas Salk developed a polio vaccine in the nineteen sixties.
Jonas Salk developed the first polio vaccine in 1952. It was a intradermal injection vaccine.
Jonas Salk developed the first vaccine in 1952.
Jonas Salk developed an inactivated virus polio vaccine in 1952 that was first used on people in 1955. Albert Sabin developed a live vaccine in 1958. It was the Sabin vaccine that was used to eliminate Polio around the world, but it was then removed from service because of its higher rate of induced disease.
I think that polio was virulent before 1955 when the vaccine was developed. Now, I think, since we have developed a vaccine, it isn't as virulent.
The vaccine for poliomyelitis (polio) was developed by Dr. Jonas Salk in the early 1950s. Salk's inactivated polio vaccine (IPV) was first tested in 1954 and became widely available in 1955. Later, Albert Sabin developed an oral polio vaccine (OPV) that became popular for mass immunization campaigns. Both vaccines have played crucial roles in reducing polio incidence worldwide.
Albert Sabin founded the oral polio vaccine and the vaccine was licensed in 1962.
To protect against polio.
Jonas Salk developed the polio vaccine, known as the inactivated polio vaccine (IPV). The vaccine was used to prevent poliomyelitis, a highly infectious viral disease that can cause paralysis and, in severe cases, death.
