The limited evidence available is low quality and suggests that face to face interventions to inform or educate parents about childhood
vaccination have little to no impact on immunisation status, or knowledge or understanding of vaccination. There is insufficient evidence
to comment on the cost of implementing the intervention, parent intention to vaccinate, parent experience of the intervention, or adverse
effects. Given the apparently limited effect of such interventions, it may be feasible and appropriate to incorporate communication
about vaccination into a healthcare encounter, rather than conduct it as a separate activity.
