Methods for conducting systematic reviews of targeted vaccination strategies for the guide to community preventive services.

his paper describes the qualitative methods adopted by the Task Force on Community Preventive Services (Task Force) to evaluate the vidence on effectiveness of interventions to improve argeted vaccine coverage. The Task Force used the ame three conceptual categories as in their earlier eview of interventions to increase universally recomended vaccine coverage (increasing community deand, enhancing access, and provideror system-based nterventions). In the current review, the Task Force ound that (1) few studies described the effects of ndividual interventions implemented alone, (2) most tudies evaluated interventions implemented in combiation, and (3) most combinations involved more than ne conceptual approach. The Task Force examined he evidence of effectiveness for all possible combinaions across categories. This qualitative process proided the Task Force with sufficient evidence to support recommendation for the use of intervention ombinations.
