Theme 3: Vaccine delivery and confidence

The overarching aim of the ‘Vaccine Delivery & Confidence’ research theme is to understand factors that contribute to challenges in programme delivery and performances, lack of public confidence in immunisation and poor vaccine uptake.

The aim is to collect date that will help determine ways to resolve these issues. Our research strategy focuses both on the organisation of health systems involved in the immunisation programme and populations with poor vaccination coverage (e.g. elderly, risk groups aged <65 years, pregnant women, health care workers, urban migrants) in order to improve coverage and programme efficiency.

In addition, the plan is to be responsive and flexible and to make use of on-going data produced by Public Health England in order to tailor subsequent research to under-served populations and particular concerns that arise. We aim to deliver results that feed directly into policy recommendations to ensure that the immunisation programme and related health systems can respond intelligently, rapidly and effectively. 


  • Delivering immunisation in the context of organisational change
    Tracey Chantler, Saumu Lwembe, Sandra Mounier-Jack
    In this study we are evaluating how the national immunisation programme in England is adapting to changes in the health care environment, with a particular focus on programme delivery and performance.
  • Parental concerns about the school-aged influenza vaccination programme
    Pauline Paterson, Tracey Chantler, Heidi Larson
    Some parents did not consent to their child being vaccinated as part of school based influenza immunisation pilots. The purpose of this study is to learn more about their concerns in order to inform future implementation.
  • Understanding factors influencing vaccination uptake among ethnic minorities during pregnancy: A qualitative study of pregnant women and healthcare workers in England.
    Rose Wilson, Pauline Paterson, Heidi Larson
    This doctoral study explores perceptions of pertussis and influenza vaccination during pregnancy.
