Abstract
Objectives: To assess the impact of a video on pertussis vaccination intentions among pregnant women and identify factors influencing their decision-making.
Materials and Methods: This quasi-experimental study was conducted from June to August 2023. Participants were pregnant women between 27 and 36 weeks of gestation. Both intervention and control groups received standard prenatal care and completed a questionnaire. The intervention group additionally watched a video on the pertussis vaccine and repeated the questionnaire.
Results: A total of 80 participants were enrolled, with 41 in the intervention group and 39 in the control group. The groups were similar in characteristics except for gestational age (29.78 ± 2.34 vs 31.69 ± 2.45 weeks, p < 0.001). Vaccination decision-making did not differ significantly between groups (p = 0.624), though the intervention group showed higher post-video knowledge scores (6.48 ± 1.62 vs 7.19 ± 1.05, p = 0.022). The intervention group exhibited a 42% increase in vaccination intentions, particularly among initially undecided participants. Key factors influencing increased vaccine acceptance in the intervention group included improved knowledge, safety concerns, cost, and medical personnel recommendations.
Conclusion: Viewing the video increased vaccination intentions by 42%, particularly among women who were initially uncertain about vaccination.
