Introduction: The development and initial assessment in a clinical setting of a theory-driven, individually tailored educational application (app), MomsTalkShots, focused on increasing uptake of maternal and infant vaccines is described.
Methods: MomsTalkShots algorithmically tailored videos based on parent needs to deliver an intervention that was specifically responsive to individual vaccine attitudes, beliefs and intentions, demographics, and source credibility. MomsTalkShots was evaluated among 1103 pregnant women recruited from 23 geographically and socio-demographically diverse obstetrician-gynecologist offices in Georgia and Colorado in 2017. Self-reported information needs were assessed pre-and post-videos and participants self-reported factors related to usability and analyzed in 2018.
Results: The vast majority of women reported MomsTalkShots was helpful (95%), trustworthy (94%), interesting (97%) and clear to understand (99%), none of which varied by demographics or parity. Reported usability was slightly lower among vaccine hesitant women, yet the majority reported MomsTalkShots was helpful (91%), trustworthy (85%), interesting (97%) and clear (99%). The majority of women (72%) who did not have enough vaccine information pre-videos reported enough information post-videos.
Conclusions: MomsTalkShots was designed to provide individually tailored vaccine information to pregnant women from a population with varied vaccine intentions, confidence and vaccine concerns. MomsTalkShots was extremely well-received among pregnant women, even among women who were initially vaccine hesitant and did not intend to vaccinate themselves and their infants according to the recommended immunization schedule. Next steps include evaluation to assess impact on vaccine uptake and expansion to adolescent and adult vaccines.
