The advocacy advert below comes from the UK branch of UNICEF, and it's pretty grim.

It sees a young boy, bruised and bloody, making his way into a pharmacy to get a prescription for gang violence from the helpful pharmacist. Handing him over a bottle of medicine, the pharmacist advises the battered boy to take a drop from off a sugar cube, telling him "It'll keep you safe, okay?"

Sadly, as the advert plays out, we see the truth behind the situation, and get reminded that when it comes to tackling violence against children, "There's no vaccine. There's only you."
