ZimbabweÃs second round of its 2007 Child Health Days began this Monday. This critical campaign targets two million children with polio vaccine and basic childhood immunisation.Now in its third consecutive year, Child Health Days have played a significant role in raising immunisation rates and boosting child-survival-efforts in Zimbabwe. 40 year old Edith Mwanyali regrets that in the past she has missed the opportunity to protect her children. Mrs Mwanyali says home visits and strong information campaigns ensured she was aware of this weekÃs Child Health Days. The community mobilisation has been critical to the success of the Child Health Days. Tens of thousands of selfless, hardworking medical staff and volunteers underscore why there is so much reason to be positive in Zimbabwe.
