In this day and age, one would wonder why an ancient disease such as polio still exists. That's not to say there have been no developments in the field of vaccine formulation and immunization. In fact, polio has been eliminated in developed nations. The sad part is that polio still persists in India, Nigeria, Afghanistan, and Pakistan - all emerging countries (read: poor countries). The infectious disease continues to cripple populations with overcrowded living conditions and poor sanitation.

The World Health Organization (WHO) will have none of that... in the next decade, that is. Experts have identified new vaccine strategies that could get rid of polio, for good. The solution is in the form of "monovalent vaccine against the strain in India from the standard trivalent vaccine that protects against three types of polio virus". 

It's been almost 19 years since WHO launched the Global Polio Eradication Initiative. If the new vaccine strategy works, we can all say goodbye to the debilitating disease. Sayonara. Au revoir. Arrivederci. Hasta la vista...
