Country Representative of the foundation, Mairo Mandara, disclosed this in Abuja on Sunday.
She said that the foundation does not estimate how much will be invested on a nation but based its investments on the needs on ground.
Mandara said facts showed that the foundation was experiencing the fastest growth the world had ever seen and that through it, 122 million children’s lives had been saved since 1990.
She further explained that mortality in children under the age of five caused by pneumonia, diarrhoea and malaria had decreased across sub-Saharan Africa.
The Country Representative assured that efforts are on to kick polio out of Nigeria this year, stating that eradication of polio in Nigeria will be the foundation’s greatest achievement.
