World Polio Day was observed on Tuesday to raise awareness about the significance of polio vaccination and protection of every child from this disease.

World Polio Day also provides an opportunity to highlight global efforts toward a polio-free world and honor the tireless contributions of those on the frontlines in the fight to eradicate this disease from every corner of the globe.

In his message on the occasion, Speaker National Assembly Raja Pervez Ashraf has urged the parents to complete the course of polio vaccination for their children to protect them against the disease.

He said currently, only four countries in the world are left with the polio virus, including Pakistan.
