How MMV estimates impact

How MMV estimates impact

Our cumulative impact 

MMV products have effectively treated or protected ~640 million people and saved an estimated 13.6 million lives (absolute impact)/1.4 million lives (relative impact).

How we calculated 

The number of people effectively treated or protected is estimated from the cumulative volume of MMV-supported products since the launch of each product. 

Estimated numbers of doses needed per treatment are used to convert volumes into numbers of potential treatments, resulting in the theoretical number of people treated or protected. The theoretical number of people treated or protected is then adjusted for wastage, sales and appropriate use (i.e., excluding use of antimalarials in non-malarial cases or drugs indicated for severe malaria in uncomplicated cases) to obtain the estimated number of people effectively treated or protected.

It is estimated that 1.1 billion people have received an MMV-supported product and that 640 million of these were appropriately treated.

The absolute number of deaths averted uses the estimated number of people effectively treated or protected for each product to derive the number of lives saved based on published clinical trial results for that product. It is an estimate based on the assumption that no other treatments would be provided if an MMV-partnership product was not available. The relative number of deaths averted represents the impact of MMV-supported products versus the situation where the MMV-supported products were not available and alternatives were provided. The protective or curative effect of each MMV-supported product is compared with that of the most likely alternative treatment option, based on published clinical trial results.

For example, MMV-supported injectable artesunate is compared to injectable quinine. Where there is no direct comparator (e.g., SPAQ for SMC), the product is compared to the absence of treatment.
