**Core Concept**
The oral polio vaccine (OPV) is a live, attenuated vaccine designed to provide immunity against poliomyelitis, a highly infectious disease caused by the poliovirus. The development of OPV marked a significant milestone in the global effort to eradicate polio.

**Why the Correct Answer is Right**
The oral polio vaccine was developed by Albert Sabin, a Soviet-American medical researcher. Sabin's vaccine was a major improvement over the earlier inactivated poliovirus vaccine (IPV) developed by Jonas Salk, as it was easier to administer and provided longer-lasting immunity. The Sabin vaccine contains three strains of live, attenuated poliovirus, which are administered orally to stimulate a mucosal immune response.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not specify a well-known contributor to the development of the oral polio vaccine.
**Option B:** This option is incorrect as it is not a recognized figure in the history of polio vaccine development.
**Option C:** This option is incorrect as it does not accurately identify the developer of the oral polio vaccine.

**Clinical Pearl / High-Yield Fact**
It is essential to remember that the oral polio vaccine was a crucial innovation in the fight against polio, allowing for widespread vaccination campaigns and ultimately contributing to the near-eradication of the disease. The Sabin vaccine's live, attenuated nature also made it more effective at preventing transmission of the virus in areas with poor sanitation.

**Correct Answer: C. Albert Sabin**
