The NHS is launching a major campaign in the region to encourage more people to give blood.

Sixteen-year-old Christie Dalgleish from Carlisle is only alive today because of seventy tranfusions she received after developing aplastic anaemia three years ago.
Her mother, Jennifer Dalgliesh, says that the importance of people giving blood cannot be overstated.
