NCT03966300

Brief Summary

Vaccination hesitancy is identified as a threat to global health by the World Health Organization (WHO). For adolescents undergoing vaccination at school, prior studies demonstrate that concerns about pain and/or fear of needles contribute to negative experiences with vaccination and non-compliance with vaccination. The investigators developed an intervention that addresses vaccination hesitancy. In this study, investigators will evaluate the effectiveness of this intervention in a randomized controlled trial.

Outcome Measures

Primary Outcomes (1)

  • Student fear

    student self-reported fear during vaccination, rated on a 0-10 scale

    within 5 minutes after vaccination

Secondary Outcomes (13)

  • Student pain

    within 5 minutes after vaccination

  • Student dizziness

    within 5 minutes of vaccination

  • Student fainting

    within 1 hour after vaccination

  • Student post-immunization stress-related responses

    within 1 hour after vaccination

  • Utilization of coping strategies

    within 5 minutes after vaccination

  • +8 more secondary outcomes

Study Arms (2)

CARD (multi-faceted knowledge translation intervention)

EXPERIMENTAL

CARD will be integrated into the school vaccination program. This includes pre-vaccination day preparation (e.g., planning of clinic spaces, student and school staff education about CARD) and vaccination day activities (e.g., clinic set-up, processes for triaging students, implementing pain/fear/fainting mitigation interventions from CARD during vaccination)

Other: Multi-faceted knowledge translation intervention

Control (standard/usual care)

NO INTERVENTION

There are no specific procedures being undertaken to plan or execute clinics. Usual practices will be instituted (i.e., no education specific to CARD, nor clinic set-up or execution to incorporate interventions for pain, fear or fainting)

Interventions

The intervention consists of education of relevant stakeholders of best practices and integration of best practices into the vaccination delivery program

Students will not be aware of whether they are in the intervention or control group. Care providers who are trained in the intervention are aware of the group allocation. They will not communicate with care providers not trained in the intervention. Care providers that are trained in the intervention will not deliver care to participants in the control group and care providers that are not trained will not deliver care to participants in the intervention group
