A cluster randomised controlled trial of a web based decision aid to support parents’ decisions about their child's Measles Mumps and Rubella (MMR) vaccination

Abstract

HighlightsThe use of decision aids for immunisation decisions is under researched and controversial.Parents receiving a decision aid or a leaflet had reduced decisional conflict for the MMR decision.MMR uptake in the decision aid and control arms achieved levels required for population immunity.Leaflet arm parents were less likely to vaccinate their child.Childhood immunisation decision aids can achieve both informed decision-making and uptake.

Vaccine Message Framing and Parents’ Intent to Immunize Their Infants for MMR

“…This work contributes to the emerging literature about vaccine communication with parents and can provide additional evidence to inform MMR vaccine communication approaches and perhaps vaccine communication in general. With growing interest in childhood vaccine decision aids, 49 evidence-based approaches are critical to ensuring effective communication about childhood vaccines. Moreover, this work suggests a pattern of parental focus on the child' s well-being, perhaps to the exclusion of concerns about population health.…”

Cost effectiveness of a web-based decision aid for parents deciding about MMR vaccination: a three-arm cluster randomised controlled trial in primary care

“…The trial 16 concluded that, of the two interventions, only the decision aid achieved both informed decision making and MMR uptake.…”

“…16 A total of 220 first-time parents whose first child was offered the first MMR vaccine dose (aged 3-12 months) received either:…”

“…10 The concern about using decision aids in the context of vaccination is that encouraging people to deliberate about their MMR beliefs may affect their motivation to vaccinate. [11][12][13] However, increasing evidence, 14,15 including the findings from the recently published Detailed Evaluation of a Childhood Immunisation Decision Aid (DECIDA) study, 16 suggests that decision aids for childhood vaccination decisions may actually achieve both informed decision making and increased vaccine uptake.…”

What are the factors that contribute to parental vaccine-hesitancy and what can we do about it?

“…Shourie et al conducted a three-arm cluster randomized trial comparing the use of a MMR decision aid, to a MMR informational leaflet, to usual care. 45 Decisional conflict was reduced in both intervention arms; children whose parents were in the leaflet arm were less likely to be vaccinated with MMR (91%) compared with the decision aid (100%) and control (99%) arms (P D 0.017). Wroe et al conducted a prospective interventional trial comparing the impact of a 20 page manual on the benefits and risks of childhood vaccinations to support vaccination decisions (intervention) to a less in depth 19 page leaflet published by the Ministry of Health (control).…”
