Polio
Polio is a paralyzing disease that has no cure. Multiple doses of the oral polio vaccine and completion of the routine vaccination schedule for all children under the age of five is essential to provide children high immunity against this terrible disease.
The Pakistan Polio Program conducts multiple mass vaccination drives in a year, bringing the vaccine to children at their doorsteps, while the Expanded Program on Immunization provides vaccinations against 12 childhood diseases free of charge at health facilities.
Parents must ensure vaccination for all their children under the age of five to keep them protected.
