Check the vaccine
The department of health and family welfare introduced the pulse polio immunisation programme in 1995. Since then, many rounds of national and sub-national anti-polio days have been observed and numerous children aged up to five administered the oral polio vaccine (opv).
However, polio continues to afflict. And, what is more terrifying, many children have developed the disease even after taking ten or more doses of opv. Why has the vaccine failed to protect? Common sense dictates that there can be two reasons. Many children might not respond to the vaccine because of some factors in their body, known as inhibitors. It is also possible that the vaccine might have been of poor quality
