Which of the following is an inactivated (killed) polio vaccine developed in 1952?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. Salk vaccine.

  •  The Salk vaccine is the inactivated (killed) polio vaccine developed by Dr. Jonas Salk in 1952. It is an inactivated polio vaccine (IPV), which means it uses a killed version of the poliovirus to stimulate an immune response without causing the disease.
  • The Salk vaccine is typically administered via injection. The introduction of the Salk vaccine significantly reduced the incidence of polio in many countries and was a crucial step in the global effort to eradicate the disease.
