World Polio Day

Every year the World Polio Day is celebrated on October 24. The day is celebrated to increase the awareness to eradicate polio. It was established by the Rotary International. It is an international organization that aims to provide humanitarian services by bringing together business professional and other people together.

Why on October 24?

The World Polio Day is celebrated on October 24 to mark the birth of Jonas Stalk. Jonas Stalk is the first American virologist who developed the polio vaccine. However, the oral polio vaccine (OPV), that is now widely used was developed by Albert Sabin. Albert developed the OPV based on Stalk’s inactivated vaccine. The OPV invention led to the establishment of GPEI (Global Polio Eradication Initiative).

  • 6 weeks: OPV – 1 and IPV – 1
  • 10 weeks: OPV – 2 and IPV – 2
  • 14 weeks: OPV – 3 and IPV – 3
  • 15 to 18 months: OPV – 4 and IPV – B1
