Seconds. That's the difference between life and death. I've seen it firsthand, in Gaza, in Syria, in Sudan.

I'm Javid Abdomenem, a doctor with Medt Sins-Saint-Saint-Fontierre. As conflicts continue to spread across the world,

it's crucial we can act fast. As an MSF doctor, I may need to stop life-threatening bleeding,

treat gunshot wounds, or care for blast victims, all in a matter of seconds.

That's why, at Medicines-on-Fontierre, we don't waste any time.

You can buy us vital time.

Please give just £30.
