Background
Vaccination has transformed public health by preventing millions of deaths and protecting communities from vaccine-preventable diseases. Yet despite decades of scientific evidence demonstrating that vaccines are safe and do not cause Autism Spectrum Disorder (ASD), misconceptions and concerns about vaccine safety continue to influence parental decision-making.
For parents of children diagnosed with ASD, these concerns may be shaped by personal experiences, misinformation, or uncertainty surrounding childhood immunization. As a result, vaccine hesitancy remains a complex public health issue that extends beyond vaccination rates alone.
To strengthen vaccine confidence and improve public health outcomes, researchers must first understand the beliefs, attitudes, and concerns that influence parents’ decisions. This study sought to generate local evidence on vaccine hesitancy among Filipino parents of children with ASD and identify factors associated with their vaccination attitudes.
The Research Challenge
The research team aimed to determine the prevalence of vaccine hesitancy among Filipino parents of children diagnosed with Autism Spectrum Disorder (ASD) and identify factors associated with their vaccination attitudes.
The study explored questions such as:
- How prevalent is vaccine hesitancy among parents of children with ASD?
- Which socio-demographic characteristics are associated with vaccine hesitancy?
- What factors influence parents’ attitudes toward childhood immunization?
- How can understanding vaccine hesitancy help improve public health communication and intervention strategies?
Beyond estimating prevalence, the project addressed a broader public health challenge: understanding why parents become hesitant and how evidence can be used to strengthen trust in immunization programs.
Data2Stats’ Role
Data2Stats provided comprehensive statistical support throughout the project, helping transform survey data into meaningful evidence that can inform future public health initiatives.
The team supported the study through:
- Research consultation and guidance on study objectives and methodology;
- Data cleaning, validation, and quality assurance;
- Development of the statistical analysis plan;
- Statistical analysis and interpretation of findings;
- Preparation of publication-ready tables and summaries; and
- Assistance in developing research recommendations and interpreting study results.
By ensuring that the data were carefully managed and appropriately analyzed, the project generated reliable evidence that can contribute to discussions on vaccine confidence, health communication, and childhood immunization.
Statistical Methods Used
Several statistical methods were employed to address the study objectives.
Descriptive statistics were used to summarize participants’ socio-demographic characteristics and estimate the prevalence of vaccine hesitancy among parents of children with ASD.
An adapted Vaccine Hesitancy Questionnaire based on Migrino et al. (2019) was administered to assess parental beliefs, concerns, and attitudes regarding childhood vaccination.
Additional association analyses were conducted to examine relationships between vaccine hesitancy and selected socio-demographic characteristics. These analyses allowed the researchers to identify factors that may influence vaccine attitudes and inform future public health interventions.
Microsoft Excel (Windows, 2026) was used for data management, while Epi Info Version 7 was utilized for statistical analysis.
What the Data Revealed
The study is expected to provide valuable local evidence on vaccine hesitancy among Filipino parents of children diagnosed with Autism Spectrum Disorder.
The analysis will estimate the prevalence of vaccine hesitancy, describe the socio-demographic profile of participating parents, and identify factors associated with vaccine attitudes.
Rather than focusing solely on vaccination rates, the findings are expected to provide deeper insights into the beliefs, concerns, and sources of information that shape parental decision-making. These insights can help researchers and healthcare professionals better understand the barriers to vaccine confidence and develop communication strategies that address community-specific concerns.
Ultimately, the study aims to generate evidence that supports more effective and context-specific approaches to strengthening childhood immunization programs.
A Valuable Lesson in Clinical Research
Vaccination decisions are rarely based on facts alone.
Parents often weigh personal experiences, perceived risks, advice from healthcare providers, and information from various sources before deciding whether to vaccinate their children.
This study highlights an important lesson in public health research:
Understanding vaccine hesitancy is about more than measuring vaccination rates.
By exploring the reasons behind vaccine attitudes, researchers can move beyond identifying who is hesitant to understanding why hesitancy exists.
These insights provide a stronger foundation for developing evidence-based communication strategies that build trust, address misconceptions, and encourage informed health decisions.
In public health, understanding people’s questions is often the first step toward finding meaningful solutions.
Outcome and Impact
The project is expected to generate valuable local evidence on vaccine hesitancy among Filipino parents of children with Autism Spectrum Disorder and provide insights that may strengthen future immunization initiatives.
More importantly, the study demonstrates the value of rigorous statistical support in helping researchers:
- Estimate the prevalence of vaccine hesitancy;
- Identify factors associated with vaccination attitudes;
- Translate survey findings into meaningful public health insights; and
- Develop evidence-based recommendations that support effective health communication.
The findings may contribute to context-specific strategies that strengthen vaccine confidence, improve public understanding of immunization, and support informed decision-making among parents.
Key Takeaways
- Vaccine hesitancy is influenced by beliefs, concerns, and sources of information, not simply vaccination status.
- Understanding parental attitudes is essential for developing effective public health communication strategies.
- Local evidence can help guide interventions that address community-specific concerns and strengthen vaccine confidence.
- Rigorous statistical analysis transforms survey data into actionable insights for researchers and policymakers.
- Understanding why parents hesitate is an important step toward building trust and improving childhood immunization programs.
At Data2Stats, we believe that statistical analysis is about more than measuring prevalence. It is about uncovering the factors that shape health decisions, enabling researchers to generate evidence that informs better communication, strengthens public confidence, and supports healthier communities through evidence-based public health action.
