Mass media reaches millions of people and can stimulate significant shifts in behaviour when the right messages reach the right people.

We have conducted the first randomised controlled trials (RCTs) to prove that mass media campaigns can change behaviours and improve health. Results from our first RCT show that our radio campaign increased malaria diagnoses by 56% and modelling suggests it saved an estimated 3,000 lives in Burkina Faso.

We have since delivered similar campaigns in seven countries, saving an estimated 22,000 lives between 2020 and 2025.

We are committed to using the most rigorous methodologies feasible to continue to achieve and demonstrate our impact at scale.
