A cluster randomized trial to determine the effectiveness of a novel, digital pendant and voice reminder platform on increasing infant immunization adherence in rural Udaipur, India

Effect of vaccine reminder and tracker bracelets on routine childhood immunization coverage and timeliness in urban Pakistan: a randomized controlled trial

“…This corresponds to findings from other studies where caregivers in a variety of settings have expressed the need and desire for innovative and novel reminder/recall mechanisms [26] [27]. This finding is also in line with results of the study in Udaipur, India where mothers expressed increased satisfaction and acceptability for the novel digital pendant as compared to the traditional immunization reminder mechanism [18]. Our finding, therefore, serves as an important validation of the bracelets in the context of their health-oriented value.…”

“…Overtime, the utility of wearables for health has expanded across different disease domains and in recent years, the line between consumer health wearables and medical devices has begun to blur [16]. The upsurge of wearables is mostly concentrated in developed countries, but the concept has gained traction in low and middle-income countries as well where wearable solutions integrating data records such as tattooed bracelets for immunization [17], Near Field Communication (NFC) powered digital pendants [18] and Vaccine Indicator Reminder (VIR) bands [19,20] are coming to the forefront.…”

Effect of vaccine reminder and tracker bracelets on routine childhood immunization coverage and timeliness in urban Pakistan (2017-18): a randomized controlled trial

“…This corresponds to ndings from other studies where caregivers in a variety of settings have expressed the need and desire for innovative and novel reminder/recall mechanisms [26] [27]. This nding is also in line with results of the study in Udaipur, India where mothers expressed increased satisfaction and acceptability for the novel digital pendant as compared to the traditional immunization reminder mechanism [18]. Our nding, therefore, serves as an important validation of the bracelets in the context of their health-oriented value.…”

“…Despite their growing in uence, currently, there is limited published literature investigating the impact of these innovative tools. Our study is among the rst few attempts to rigorously investigate the impact of these innovations, and our ndings are corroborated by a similar study in the region which reported that a Near Field Communication (NFC) powered digital pendant worn as a necklace around the child's neck did not have any signi cant impact on DTP-3 vaccination adherence [18].…”

Vaccine hesitancy among caregivers and association with childhood vaccination timeliness in Addis Ababa, Ethiopia

“…29 Additionally, some authors have attributed unmeasured confounding and residual vaccine defaulting behaviors to vaccine hesitancy without identifying a root cause or exploring the potential linkages between hesitancy and vaccination outcomes. 30 It is important to note that vaccine hesitancy is unlikely to be the sole factor explaining untimely vaccination, and other factors, including health literacy, may play a significant role. Nearly 50% of the surveyed respondents had an elementary education or less, indicating that level of schooling and insufficient health literacy may have explained some of the hesitancy or untimeliness of vaccinations.…”
