Understanding Vaccine Hesitancy in Parents: A Machine Learning Approach

This observational study aims to explore the factors influencing vaccine hesitancy among parents of children aged 0-48 months using machine learning techniques. With an estimated enrollment of 600 participants, the research focuses on parents who are proficient in Turkish, can access social media platforms, and have children without absolute contraindications to vaccination. The study will employ a non-probability sampling method, specifically snowball sampling, to reach participants via platforms like Instagram and WhatsApp between June and September 2025.

Why This Study Matters: Vaccine hesitancy is a growing concern worldwide, as it can lead to lower vaccination rates and increased risk of preventable diseases. Understanding the reasons behind this hesitancy is crucial for developing targeted interventions to improve public health. This study is particularly important because it uses machine learning to predict hesitancy, offering a data-driven approach to address this complex issue.

Key Aspects of the Study:

• Participants: Parents aged 18 and older with children aged 0-4 years, who are willing to participate and meet the inclusion criteria.
• Measurement Tool: The Vaccine Hesitancy Scale, which includes 21 items across four subscales, will be used to assess hesitancy levels.
• Outcome: The primary outcome is the parental vaccine hesitancy status, measured on the first day of the study via an online questionnaire.

General Considerations: Vaccine hesitancy is influenced by a variety of factors, including misinformation, cultural beliefs, and lack of trust in healthcare systems. Research like this is vital to identify these factors and develop strategies to counteract them. By leveraging machine learning, the study can uncover patterns and predictors of hesitancy that might not be evident through traditional methods. This could lead to more effective public health campaigns and policies.

For parents and caregivers, understanding vaccine hesitancy can help in making informed decisions about their children's health. It also highlights the importance of open communication with healthcare providers to address any concerns or misconceptions about vaccines. This study contributes to the broader effort to ensure that all children receive the protection they need against preventable diseases.
