Definition
  1. Noun:
    • A specific type of polio vaccine: The Salk vaccine is an immunization against poliomyelitis. It is made from poliovirus that has been killed (inactivated). It is administered via injection under the skin (subcutaneously) to stimulate the body's immune system to develop protection against the disease.
Usage Examples
  • Noun:
    • The introduction of the Salk vaccine led to a dramatic decline in polio cases.
    • Children in the 1950s often received the Salk vaccine.
    • The Salk vaccine uses inactivated virus, unlike the oral Sabin vaccine which uses a live, weakened virus.
Advanced Usage
  • The term is often used in historical and medical contexts to distinguish this injectable, inactivated vaccine from the later-developed oral polio vaccine (OPV).
    • The success of the Salk vaccine paved the way for global polio eradication efforts.
Variants and Related Words
  • Polio vaccine (n): The general term for any vaccine against poliomyelitis.
  • Inactivated poliovirus vaccine (IPV) (n): The technical, generic name for the type of vaccine invented by Jonas Salk. "Salk vaccine" is a proprietary eponym for IPV.
  • Sabin vaccine (n): The oral polio vaccine (OPV) that uses a live, attenuated virus, named for its developer, Albert Sabin.
Synonyms
  • IPV: Inactivated poliovirus vaccine (this is the direct technical synonym).

Notes on Meaning

  • It denotes a product and a medical breakthrough, not an action or abstract concept.
Noun
