Measuring Behavioural and Social Drivers of vaccination – BeSD projects
 

Investigators: Julie Leask, Kerrie Wiley, Adeline Tinessia, Madeleine Randell

 Funding: World Health Organization and NHMRC

Timeframe: 2022-2026

Project Description:

SABII is working with the World Health Organization to support the implementation of tools for Measuring the Behavioural and Social Drivers of Vaccination (BeSD). Such tools include surveys and in-depth interview guides for both childhood vaccination and COVID-19 vaccination, specifically designed for low-resource settings along with guidance on how to use the tools. Between 2010 and 2022, Professor Leask chaired a working group, that included Dr Wiley, developing the tools which have been used in multiple countries to inform policy and programs. The tools aim to:

 (a) Enable vaccination programmes and partners to boost the quality, availability and use of data on vaccination determinants;

(b) Monitor differences between (and within) countries and track trends over time at a sub-national, national and global level;

(c) Provide programme managers with actionable insights through user-friendly practical guidance for planning, data collection and analysis.

Measuring the Behavioural and Social Drivers of Influenza Vaccination in Australia
 

Investigators: Julie Leask, Maria Christou-Ergos, Majdi Sabahelzain, Margie Danchin (MCRI), Jessica Kaufman (MCRI), Maryke Steffens (NCIRS), Kasia Bolsewicz (NCIRS)

Funding: NHMRC

Timeframe: 2023-2024

Project Description:

SABII researchers will systematically investigate reasons for suboptimal influenza vaccine coverage in Australia. This study will address the lack of data measuring sentiment towards influenza vaccination at a national level.

 

We will work closely with the World Health Organization to adapt and validate existing tools to measure the Behavioural and Social Drivers of Influenza vaccination. The adapted survey will measure reasons for low influenza vaccine coverage in a large sample of Australian adults and in-depth interviews will give additional insights. SABII researchers are working closely with the Social Science team at the National Centre for Immunization Research and Surveillance and the Murdoch Children’s Research Institute to understand the findings.

 

Findings will help immunization program managers design appropriate interventions to improve influenza vaccine delivery and uptake. Ongoing monitoring of the Behavioural and Social Drivers of Influenza vaccination will facilitate comparisons in sentiment over time to further refine timely interventions and prompt action to address reductions in confidence.

Perceptions and demand for routine immunization and other maternal and child health services during COVID-19 pandemic among caregivers and healthcare workers in Indonesia
 

Investigators: Julie Leask, Meru Sheel, Mu Li, Madeleine Randell and Adeline Tinessia (USyd), Tri Yunis Miko Wahyono and Oktarinda Miko (Universitas Indonesia), Margie Danchin (MCRI), Michelle Dynes (UNICEF EAPRO), Kylie Jenkins (consultant)

Funding: UNICEF East Asia and Pacific Regional Office (EAPRO)

Timeframe: 2021 – 2023

Project description: 

The COVID-19 pandemic had a significant impact on maternal and child health services in Indonesia. This was due to reduced access to key services as well as fear of COVID-19 driving reluctance to attend services. One outcome of this was a decline in routine immunisation coverage among young children. Despite a COVID-19 vaccine roll-out in January 2021, only 66% of adults had received their second dose and 20% had received their third dose by April 2022.  

This study aimed to better understand the influence of the COVID-19 pandemic on access to routine immunization, other maternal and child health services and COVID-19 vaccination amongst caregivers of young children and healthcare providers in Central Java and West Nusa Tenggara, Indonesia. We used the BeSD surveys with additional questions developed with a technical advisory group. In total, 1399 caregivers and 604 healthcare providers from eight districts across two provinces, i.e., Central Java and West Nusa Tenggara, participated in a cross-sectional survey. Data collection of the study was conducted in March to April 2022 and findings have been published: Influence of the COVID-19 pandemic on caregiver beliefs and experiences of routine childhood immunisation in Indonesia

Psychological trauma: Understanding vaccine hesitancy in relation to psychological trauma
 

Investigator: Maria Christou-Ergos (PhD Candidate)

Supervisors: Prof. Julie Leask and Dr. Kerrie Wiley

Funding: NHMRC Centre of Research

Timeframe: 2020-2023

Project description:

The aim of this research was to understand how the experience of psychological trauma influences vaccination decisions. It built on what is known about vaccine hesitancy and developed a trauma-informed vaccination interventions for vaccine delivery services. It included; (a) a qualitative exploration of how medical trauma influences the vaccination decisions of non-vaccinating parents; (b) a national survey investigating associations between vaccine hesitancy and traumatic life events, symptoms of post-traumatic stress disorder, and the traumatic vaccination experiences of others; (c) a survey of older Australians and associations between vaccine hesitancy and traumatic events, social support and psychological distress; (d) a guidance for vaccination providers to improve the vaccination experiences of people affected by trauma.

An examination on the functionality and impact of EU health and national vaccination laws and policies during the COVID-19 pandemic
 

Investigator: Nicole Batten, PhD Candidate

Supervisors: Prof. Emerita Bronwyn Winter and Dr. Kerrie Wiley

Timeframe: 2020-2024

Project Description: An examination on the functionality of EU health law during the COVID-19 pandemic and a comparative case study of national EU Member State COVID-19 vaccine policies and laws, and their effect on disease manifestations and socio-political responses. This interdisciplinary research aims to examine how the pandemic impacted health policy across the EU, demonstrating a move towards further health integration during the unprecedented crisis, disregarding the norm of maintaining state sovereignty over health issues. The research will carry out a comparative case study of the COVID-19 vaccine policies and COVID-19 epidemiological patterns of Italy, France, Sweden, Poland, and Romania. Each country is a reflection of the diversity of the EU and had a distinctive response to the pandemic. 

Exploring vaccination challenges and opportunities in conflict-affected and nomadic communities
 

Investigator: Majdi Sabahelzain

Supervisors: Prof. Julie Leask

Funding: NHMRC and the Scholars at Risk program

Timeframe: 2023-2024

Project description:

This research project aims to understand the challenges of vaccination and opportunities for improving vaccine coverage in marginalized populations such as conflict-affected communities and nomadic groups. According to the Immunization Agenda 2030 (IA 2030) and the Equity Reference Groups for Immunization (ERG), these populations have high rates of zero-dose and under-immunized children. To address this research objective, mixed-methods approaches will be used to address the research objective, including scoping/systematic reviews and qualitative approaches. The research findings will provide insights that can inform the development of equitable interventions in the future.

Promoting Vaccine Equity Through Policy and Program Approaches to Improve Vaccine Uptake for Refugee and Migrant Populations

Investigator: Ikram Abdi (Research Fellow)

Funding: NHMRC  

Timeframe: 2023-2024

Project description:

Vaccine uptake is crucial for public health, yet disparities persist amongst refugee and migrant communities due to various barriers. The aim of this project is to understand the policy and program level challenges that hinder the successful implementation of strategies designed to improve vaccine uptake within refugee and migrant populations. This project will involve two phases: (a) a scoping review, mapping out the policy and program approaches to improve vaccine uptake for refugee and migrant populations in high-income countries; (b) a qualitative study exploring policy and program level barriers to implementing strategies for improving vaccine uptake in refugee and migrant populations in New South Wales. The findings of these studies will provide policymakers and healthcare administrators with actionable policy recommendations to address vaccine equity in refugee and migrant communities in Australia. By understanding successful strategies and identifying gaps in current policies, stakeholders can develop more effective and culturally sensitive interventions to promote vaccination amongst these communities.
