This image illustrates the differences between intervention (throwing someone who is struggling a life preserver) from prevention, which is illustrated by the swimming lessons one takes before getting into the water. Intervention is like a specific antibiotic for a specific infection. Prevention is like a full-spectrum vaccine that serves to protect us before we need it. L2B is designed to be universal prevention, although it can also be used for more targeted intervention. It’s being used for all levels of prevention and intervention today, for small groups as well as individuals, so keep that in mind as you think about how you might apply it in your setting.
