The studies suggest that face to face strategies do not consistently improve either immunisation rates or parent knowledge and
understanding of vaccination, but the evidence was low to very low quality for these outcomes. Only one study measured the cost of a
face to face case management strategy. In this study, the cost of fully immunising one additional child was eight times the cost of usual
care, but the quality of this evidence was very low. No studies measured parents’ intention to vaccinate their child or parent experience
of intervention, and none of the studies looked at possible harmful outcomes related to the intervention. The results of this review
are limited by the small number of included studies, small number of outcomes measured and problems with the way the researchers
decided who should receive the intervention and with the way outcomes were assessed.
