Saudi scholarship student Waleed Seddiq has won the Harvard Medical School Annual Conference Award for his research, through which he made a medical discovery using viruses as a medicine to kill brain cancers.

Seddiq told the Saudi Press Agency (SPA): "We are currently using cold viruses, which are called genetically modified HSV, to target brain cancer. Treating a brain cancer patient has been very difficult because all current drugs cannot cross the blood-brain barrier; however, these viruses are transferred accurately to the cancerous cells in the brain through the patient's own stem cells."

He added: "The currently published research is in the clinical trial stages at Harvard University and the university's BWH Hospital."
