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).
What is Polio?
Polio is a viral disease. There is no cure for Polio. However, it can be prevented through immunization.
Polio Vaccine in India
The OPV was first introduced in India in 1979-80. In India, the vaccine is administered in the following way:
- Birth: OPV zero
- 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

IPV is Injectable Polio Vaccine. It is injected only by trained professionals. OPV is generally preferred over IPV as it is in inexpensive and also easy to administer.
