An interventional study of Parent source and Doctor source in Vaccine Hesitancy, sponsored by University of Manitoba. Completed at 1 site in Canada. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2019-10-10.
Sponsored by University of Manitoba · Not applicable, Interventional, and Health services research
Views on vaccines range from those who are strongly supportive to those who are stridently opposed and will not budge from identity-based core beliefs about vaccines. In between these poles are numerous others who can delay, be reluctant (but still accept), or refuse/accept some vaccines for their children but not others. It is for these vaccine-hesitant parents that constitute the 'middle ground' of this spectrum where the most immediate and productive gains can be made towards enhancing vaccination acceptance and improving uptake. However, navigating this noisy communications environment is difficult, given the array of confusing and conflicting information available from multiple and competing sources. To date, there is no consensus on how best to use communication to respond to vaccine hesitancy. Building on two Canada-wide surveys of parents, the goal of this research is to identify which communication strategies show the greatest impact in reducing parental vaccine hesitancy and improving vaccination intentions.
The specific objectives are to:

News story content includes process of weighing the risks/benefits of vaccinating, the importance of vaccines for community protection, and concludes with a recommendation to vaccinate.
News story content focuses on the consequences of not vaccinating (including vaccine preventable diseases) and the decisional regret.
Vaccine Hesitancy
Parent Attitudes about Childhood Vaccines (PACV). The PACV is a validated 15 question survey on vaccine hesitancy.
Time frame: Change in baseline measured up to 1 day after content delivery
Intention to Vaccinate
intention to vaccinate item using a 5 point likert scale ranging from very unlikely to vaccinate to very likely to vaccinate, and see if there is a one-response shift in participant intentions among vaccine hesitant parents.
Time frame: Change in baseline measured up to 1 day after content delivery

Ran from Jul 2018 to primary completion in Nov 2018, 4 months.
Of 82 non-industry interventional studies with no phase under Vaccination Hesitancy, half reached primary completion within 6 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 14. This study's 4 months is below that.
Counting every sponsor, half of 83 studies reached it within 5 months; a quarter within 2 and three quarters within 14.
