EPILOGUE
In 1988, the World Health Assembly launched a global initiative to eradicate polio by the end of the year 2000. This initiative was not without controversy. Some public health officials argued that polio, a potentially fatal or crippling disease, could be eradicated, so it should. In the long run, eradication would save billions of dollars.
