Correct Option: 1  

Explanation:
1950s
The polio vaccine known as oral poliovirus vaccine (OPV), was developed towards the end of the 1950s by American physician and microbiologist Albert Sabin containing live attenuated (weakened) virus and then put through its final trials in 1960 prior to formal introduction. Jonas Salk developed a "killed-virus" vaccine against polio in the early 1950s which was given by injection.
