Filter by:CONTEXT Vaccination has reduced mortality and morbidity by controlling many vaccine-preventable diseases. To prevent recurrence of these diseases, high vaccine coverages (VCs) (≥ 95%) are needed. But VCs for infants remain suboptimal, and four out of 10 parents doubt the safety and efficacy of vaccines in France. The Ministry of Health therefore decided in July 2017 to expand vaccination requirements to 11 valences now required to enter in young children collective structures. This measure, which went into effect in January 2018, has produced significant effects on VCs, but despite this, vaccine hesitancy (VH) persists in the general population at a prevalence level that fluctuates around 20% to 25%. Motivational interviewing is a collaborative conversational style that reinforces a person's own motivation and commitment to behavior change. It has been successfully tested in multiple domains related to health behavior change. It has also been adapted in Quebec in the area of vaccination and tested in maternity wards with postpartum mothers (Promovac study). Having led to an increase in the VCs of infants by an average of 7 percentage points and a 40% decrease in vaccine hesitancy, this approach has been in the process of being generalized to all maternity units in Quebec since 2017 (EMMIE program). It is indeed proving to be one of the most effective at present in improving confidence in early childhood vaccines. OBJECTIVES The main objective of this research is to provide proof of concept that, in the French context of mandatory vaccination for infants but also of high rates of VH, an educational strategy based on the principles and techniques of motivational interviewing and carried out with parents in the maternity ward in the days following delivery can reduce vaccine hesitancy (VH). The secondary objectives are as follows: - to verify that this reduction in VH is associated with a change in knowledge, attitudes, and beliefs regarding vaccines; - to verify that this reduction is sustainable (at 12 months); - to evaluate the acceptability and satisfaction of the interview for the parents METHODS This is a pragmatic randomized controlled multicenter study with individual randomization unit comparing the impact of motivational interviewing to a standard care with a leaflet on vaccination. Motivational interviewing will be carried out by trained midwives from the two participating maternity units (one in Marseille (Bouches-du-Rhône) and the other in Toulon (Var)), as part of the routine care provided to parturients. The midwives will be trained by the founding specialist of motivational interviewing in Quebec, during a two and a half day training course. This training will include a presentation of the theoretical foundations of this approach, its adaptation to the field of vaccination, and interactive games to put it into practice. The trained midwives will then be able to put this approach into practice during a one-month pilot period with parturients, during which they will be able to benefit from support in the form of a debriefing. The actual survey will only start at the end of this pilot phase. In each group, a questionnaire will be offered to the women (couples) who have agreed to participate, both before the motivational interview (or delivery of the leaflet) and after the interview (or delivery of the leaflet). The second questionnaire will be completed before discharge from the maternity hospital. A third evaluation time is planned at 12 months in both groups: it will be carried out by internet or telephone. The primary endpoint will be the change in the vaccine hesitancy score, measured by an international scale validated in French (Opel scale). Secondary endpoints will be changes in knowledge, attitudes and beliefs about vaccination between the two groups as well as satisfaction with the ME and the brochure. Randomization will be performed in blocks of 8, prior to acceptance for participation in this research. EXPECTED BENEFITS If the results of this research provide proof of concept that the educational strategy based on motivational interviewing adapted to the vaccination of infants after delivery, in maternity wards, makes it possible, in the French context, to reduce VH, this will be a major advance in public health in France. Indeed, even if the vaccination obligations introduced in January 2018 have had a positive impact on infant vaccination coverage, VH remains present in parents in a proportion that remains worrying (20 to 25% according to surveys). The results of this research will then allow us to study the conditions for generalizing motivational interviewing in order to reinforce confidence in vaccination, which is lacking in a significant part of the French population.
Synopsis: In most countries, there is an increase in the number of parents who refuse some, most or all vaccines or who adopt delayed vaccination schedule. Vaccine hesitancy (VH) is a global phenomenon that needs to be measured and addressed. However, to this date, no effective strategy has been identified. Dr Gagneur have developed and validated a new approach to educate parents of newborns about vaccination, based on motivational interviewing (MI) techniques. MI is a method to elicit and strengthen motivation for change based on the person's own arguments for change that has been shown effective for the adoption of many preventive health behaviors. This approach has been validated for vaccination during a pilot study as well as in a provincial RCT in Quebec. Now that a proof of concept has been made in Quebec, the investigators will validate the approach in other contexts (e.g. English-speaking provinces and settings with different ways to deliver maternity care and childhood vaccines). Hypothesis: An educational strategy, based on MI techniques, delivered in the maternity ward increases parents' intention to vaccinate their infant, reduces VH scores and increases infants' vaccine uptake in Quebec. This approach may be applicable across the country in order to tackle VH and thus improve infants' vaccine coverage (VC). Objective: To evaluate the impact of the MI intervention on parents' intention to vaccinate their child and their VH score and on infants' VC at 3 months of age, in a pan-Canadian context. Methods: Multicentre RCT in maternity wards of 5 provinces (QC, BC, ON, NS/PE). Parents will be randomized to receive the MI intervention (intervention group) or to receive an information flyer on vaccines (control group). MI intervention will be delivered by research assistant that will have first received a standardized training session on the content and techniques of MI. Parents will complete a self-administered questionnaire to measure knowledge and vaccination intention as well as VH before and after the intervention. Immunization data will be collected through an online questionnaire sent when the child will reach 3 months of age. Expected benefits: The strategy will be validated across different immunization programs from 5 Canadian provinces to take account of the differences in logistics and cultural contexts. Results from this study will provide to the provincial and national public health authorities an effective strategy to tackle VH.
