Combination or high-impact prevention is a set of strategically-selected interventions that matches the needs of a given country or community—and is delivered at the scale needed to make an impact. It means doing less of something and far more of others. It means making tough decisions and measuring impact. Above all, it means moving with clarity and speed.

There are emerging global definitions of what combination prevention is, and evolving models of what it can achieve. AVAC works with advocates to define what combination prevention means in a given context, track country and donor alignment with a combination prevention strategy and ensure that there is an implementation science agenda to fill in gaps in knowledge.
