Public health & disease

From disease eradication efforts to advances in vaccination and maternal health, this archive tracks real progress in public health. Stories here focus on what’s working — policies, interventions, and research that are improving and extending lives around the world.

Brain model, for article on glioblastoma vaccine

Vaccine prolongs life of patients with aggressive brain cancer in new trial

Glioblastoma patients now have the most promising new treatment in nearly three decades, after a personalised vaccine more than doubled five-year survival rates in a large international trial. The vaccine works by extracting proteins from a patient’s own tumour and combining them with their white blood cells, training the immune system to recognise and destroy the cancer — with benefits seen even among those traditionally considered hardest to treat. If regulators approve it, this could signal a new era of personalised immunotherapy for cancers that have long resisted every available option.

Human eye up close, for article on Gennaris bionic vision system

Monash University develops world’s first bionic eye to fully restore vision in blind people

Gennaris, a bionic vision system from Monash University, could open a path to sight for people whose blindness stems from optic nerve damage — a group that most existing visual aids simply cannot help. The device bypasses the eye entirely, sending signals from a camera headset directly to tiles implanted in the brain, which then create perceivable points of light. Sheep trials confirmed the implants are safe and stable in brain tissue, and human trials are now being planned. If it succeeds, the underlying technology could eventually be adapted to assist people living with paralysis too.
