Educational videos to address vaccine hesitancy in childhood immunization.

BACKGROUND

As one of the essential programs that have been developed for decades, childhood immunizations are mandatory to protect children from vaccine-preventable diseases. Despite its availability and accessibility, immunization coverage has not reached the intended goals. Vaccine hesitancy and COVID-19 pandemic may threaten immunization coverage in children. This study aimed to evaluate the tailored educational videos to reduce vaccine hesitancy and analyze the changes in childhood routine immunization status.

METHODS

This was an interventional quasi-experimental study in three subdistricts of North Jakarta, Indonesia. Participants were allocated into educational videos exposures (intervention group, n = 116) or to the digital version of the maternal and child health handbook (control group, n = 104). We administered a pre- and post-intervention vaccine hesitancy survey using the Parent Attitudes about Childhood Vaccines (PACV) questionnaire with cut-off scores of 50.

RESULTS

A total of 220 parents were recruited in this study from June 18, 2021, to December 10, 2021. The pre-intervention PACV survey showed that 19 (8.6%) parents were vaccine-hesitant from both groups: 12 (10.3%) and 7 (6.7%) of parents among intervention and control groups. After the interventions, there were 8 (6.9%) and 8 (7.7%) vaccine-hesitant parents in the intervention and control groups, respectively. We found a significant difference in the post-intervention PACV median score between the intervention and control groups (17 vs 23; p = 0.035). Around 25% of parents have not completed their children's immunization status: 22.4% and 28.8% in the intervention and control groups, respectively. There was a significant difference between the proportion of PACV hesitancy on the immunization status within intervention and control groups (p = 0.001).

CONCLUSION

There was a reduction in vaccine hesitancy after interventions. Educational videos intervention distributed through WhatsApp group was associated with lower vaccine hesitancy and can be used as health education tools among Indonesian parents in the community.
