La mano di un bambino malato tenuta dalla madre alla clinica locale di Liboi, Kenya

The hand of a sick child is held by it’s mother at a local clinic in the town of Liboi, Kenya, Wednesday, July 27, 2011.
UNICEF says it is trying to vaccinate more than 300,000 children in Kenya in an emergency program designed to prevent an outbreak of disease as refugees stream into northern Kenya from famine-hit Somalia.
