The HPRU in Vaccines and Immunisation looks at the effectiveness and safety of vaccines, how many people are being vaccinated, disease trends, and the impact of introducing new vaccines. We also look at what people think about vaccines and how we can make it easier for people to access vaccinations.


The NIHR Health Protection Research Unit in Vaccines and Immunisation is a partnership between the UK Health Security Agency (UKHSA) and the London School of Hygiene and Tropical Medicine, in collaboration with the University of Cambridge.


Our unit is one of 14 Health Protection Research Units (HPRUs) across England, part of an investment by the National Institute for Health Research (NIHR) to protect the health of the nation. The HPRUs fund high quality research that enhances the ability of UKHSA to use innovative techniques to protect the public’s health and minimise the health impact of emergencies, such as COVID-19.

Each NIHR HPRU undertakes high quality research that is used by UKHSA to keep the public safe from current and emerging public health threats.

The NIHR HPRUs focus on collaboration and knowledge sharing, and play a pivotal role in maintaining and growing UKHSA’s scientific expertise and future workforce. The multidisciplinary centres of excellence also deliver responsive research to tackle emerging or potential public health emergencies. 


The NIHR's mission is to improve the health and wealth of the nation through research. The NIHR was established in 2006 and is primarily funded by the Department of Health and Social Care.

Working in partnership with the NHS, universities, local government, other research funders, patients and the public, the NIHR delivers and enables world-class research that transforms people’s lives, promotes economic growth and advances science.

Theme 1 - Making the most of real-world data

This theme aims to increase vaccine coverage and support a data-driven immunisation programme by making the most of digital technologies and linked electronic health records. 


  • Drive evidence-based immunisation policy 
  • Improve vaccine coverage and reduce health inequalities 
  • Make the best use of data in the immunisation programme

To support an evidence-based response to COVID-19, we have undertaken studies to identify who is at risk of COVID-19, understand the effect of the pandemic on uptake of routine childhood vaccinations such as measles, and will be studying the safety and effectiveness of COVID-19 vaccination. 

An over-arching focus over the five years is understanding how to reduce health inequalities in vaccine uptake and vaccine-preventable disease, including an HPRU-funded PhD to focus on how mental health affects vaccine uptake among mothers and babies.  

We will continue to develop methods for better use of data in delivery and evaluation of the immunisation programme, and vaccine-related research. This will include an HPRU-funded PhD to develop understanding of ‘healthy vaccinee bias’ (in which people who receive vaccines tend to differ from those who do not) and methods to address this in vaccine research. 

Many of our studies make use of anonymised information from NHS patient health records, which is provided by patients and collected by the NHS as part of their care and support, and we are very grateful to the patients and NHS workers who make this possible. 

Find out more information on the value of patient data for research.

Theme 2 - Saving lives, optimising taxpayers' investment

UK Health Security Agency (UKHSA) uses models of vaccine-preventable diseases to inform (i) the Joint Committee on Vaccines and Immunisation decisions about new vaccine introductions and alterations to the existing schedule; (ii) vaccine procurement; and (iii) making the public health and economic case for investment in robust vaccine programmes.  

The methodology for economic models is mature, thanks largely to innovative research over the last 20 years arising from a collaborative partnership between staff now at LSHTM and UKHSA. However, vaccine questions grow increasingly complex and need solutions that are transparent and acceptable to both policymakers and the public. 


  • Ensuring that new vaccines save lives and optimise taxpayers' investment 
  • Making existing vaccines more efficient 
  • Reducing antimicrobial resistance through vaccination 

To ensure vaccines provide value for money we will:

  • Develop mathematical and economic models for new vaccines 
  • Examine whether vaccines can also prevent the development of resistant superbugs 
Theme 3 - Immunisation delivery systems and public interactions with vaccines

This theme will examine how immunisation systems work, and evaluate public responses to vaccination programmes. It aims to understand why targeted populations do not always seek vaccination and implementers do not always create opportunities for vaccinating them. Evidence gathered will support UKHSA to improve uptake, reduce inequalities and increase programme efficiency. 


  • Evaluate vaccine delivery models to increase uptake 
  • Understand modern social trends on vaccine uptake and vaccine confidence. We aim to complement attitudinal tracking by UKHSA, provide in-depth insight into under-vaccinate 
  • Provide evidence to strengthen immunisation systems 
  • Exploit new technologies to increase uptake and efficiency 

To sustain trust in vaccines we will:

  • Help the NHS modernise the childhood vaccine schedule in a way that is acceptable to parents 
  • Explore and respond to public concerns about vaccines through population surveys and automated analyses of online social media 
  • Provide an in depth understanding of attitudes towards and barriers to vaccination of communities with lower uptake 
  • Support evidence-based communication about vaccines

Academic Career Development
NIHR HPRU LSHTM Academic Career Development 2 columns
NIHR HPRU LSHTM Academic Career Development 2 columns left paragraph

The ethos of our HPRU is to promote learning and facilitate the career progression of all who contribute to our research programme, which includes PhD award holders, HPRU staff and other trainees. Our main goals for the duration of our grant are to:

  1. strengthen the capacity of our dynamic multi-disciplinary team to ensure that we are equipped to address current and future public health and immunisation research priorities,
  2. engage proactively with the NIHR research infrastructure to nurture mutually beneficial research collaboration and learning partnerships with other HPRUs, ARCs and BRCs, and
  3. consolidate our contribution to the training of Public Health and General Practice registrars and students engaged in post-graduate public health related courses.

To achieve these goals, we will build on our existing internal HPRU and broader institutional teaching and learning capacity and seek to access additional training support through the NIHR Academy and the broader NIHR research infrastructure.

Academic Career Development in NIHR Infrastructure and NIHR Schools


Group 1: PhD degree award holders

This group consists of PhD students, whose degree is funded by the HPRU and who have a training plan with a defined end date.


  • Provide world class doctoral training for the next cohort of public health research leaders

Group 2: HPRU Staff

This group consists of early-mid career researchers, senior investigators, and project management staff. All staff can access internal training programmes and are encouraged to complete training in teaching and doctoral supervision.  


  • Enhance the expertise of our existing multi-disciplinary research and project management team by signposting them to NIHR and other funding, fellowship and training opportunities suited to their stage on the academic/research or project management career pathway.
  • Give early-mid career researchers increased responsibility for designing, implementing and managing studies guided by theme leads

Group 3: Other trainees

This group consists of Public Health (PH), General Practice (GP) registrar trainees and LSHTM MSc students. We aim to facilitate placements and short-term research projects for these trainees. We also extend invitations to our public engagement events, such as our Annual Science Day, to all trainees within our network, so that they are provided with opportunities for gaining familiarity with HPRU research, networking, and presenting research project findings.


  • Facilitate short-term placements (defined contributions to research projects and co-authorship on manuscripts) for Public Health and General Practice trainees through: i) existing collaborations with UKHSA and NHS England immunisation teams and, ii) making connections with public health registrar training co-ordinators in London, Kent, Surrey and Sussex
  • A public-health consultant member of the HPRU (Helen McDonald) will train as a Faculty of Public Health supervisor for public health registrars.
  • Accommodate short-term dissertation related research opportunities (approx. 6-10 weeks) for LSHTM MSc students via the LSHTM Vaccine Centre and its Student liaison committee.


We have generic and group specific objectives. Our generic objectives focus on ensuring that information about training and career development opportunities are shared widely, strengthening and establishing research, and training collaborations across the NIHR infrastructure. Core objectives for PhD award holders are to ensure that they receive the support and guidance they need to complete their theses and plan their next career moves. Key to this will be encouraging them towards opportunities afforded through their NIHR Academy membership. The essence of the objectives for HPRU Staff is to signpost all staff to career stage appropriate training and development opportunities and identify those who would benefit from NIHR Academy membership to help them apply for fellowships or similar awards. The objectives for other trainees focus on ensuring that our HPRU is an outward facing resource which supports the development of non-HPRU public health researchers though training and research placements.

Pathways to Impact 

  • Regularly updated career development resources. HPRU team members contributing to NIHR facilitated research networks and involved in collaborative training and research activities.
  • Completion of 6 PhDs resulting in new researchers moving into roles that will make a difference to public health and starting their journeys to become future research leaders.
  • HPRU staff benefitting from general NIHR and NIHR Academy specific training and funding opportunities
  • Facilitation of PH & GP registrar trainee placements
  • Opportunities for MSc students to conduct immunisation related projects.


We are keen to strengthen existing and establish new research and training collaborations with HPRUs, ARCs and BRCs across the NIHR infrastructure. We also want to increase our support and engagement with Public Health and General Practice Training programmes.

Public Engagement Workshop: 18th March 2024


Group sitting at desks at NIHR HPRU public engagement workshop

The HPRU held a public engagement workshop at Friends House on 18 March 2024 with members of the public and healthcare professionals. The days' activities included interactive sessions where we discussed our research projects and gathered suggestions on how we can better involve and engage with the public throughout our research in a meaningful way. Six healthcare professionals 11 members of the public , and some members of the HPRU participated in the workshop.

The workshop began with a presentation from Louise Letley (UKHSA) which outlined the current UK immunisation schedule. This was followed by two interactive, round table sessions where attendees shared their input on the topics of “What are your priorities for vaccine research?” and “How can we best involve you in our research”? We are keen to consider learnings from these sessions as we develop our research plans and develop new outputs.

Many thanks to our thoughtful contributors! 

Increasing influenza vaccine uptake among the under 65 at risk cohort

What was this study about?

People under 65 in clinical risk groups are at risk of severe illness, hospitalisation and death from influenza, yet seasonal influenza vaccine coverage rates in this cohort are profoundly low. We explored the reasons for non-vaccination among 3 different clinical risk groups. We also interviewed healthcare providers and commissioners to understand the acceptability and feasibility of integrating vaccine programme delivery in non-primary care settings.

What did we find out?

The study found that people in clinical risk groups were often unsure about the relevance of influenza vaccines for their long-term conditions, or did not feel themselves to be at risk of severe illness from influenza. Healthcare providers rarely discussed or recommended influenza vaccines, despite being well placed to offer condition-specific information. Healthcare providers were positive about integrating vaccine programme delivery in non-primary care settings, but questions remain about feasibility due to resources and training.

COVID-19 Vaccine Coverage Snapshot
OpenSAFELY vaccination history by age graph

Three years have passed since the first doses of COVID-19 vaccines were administered in the UK. Multiple booster campaigns have been conducted each year, with varying eligibility based on age and clinical vulnerability.

To help summarise overall progress of the vaccine roll-out, HPRU researchers have collaborated with the University of Oxford to develop a new vaccine coverage ‘snapshot’. This looks at how many doses of COVID-19 vaccine people in England have typically received, how long ago they were last vaccinated, and how these measures differ by age, ethnicity, socioeconomic status, and in different clinical risk groups.

The report highlights the considerable progress of the vaccine roll-out. For example, prior to the autumn 2023 booster campaign, people over the age of 75 had typically received six doses, and 88% had been vaccinated in the last year. However, the report also highlights significant differences in vaccine uptake according to ethnicity and socioeconomic status, as well as gaps in vaccine coverage in several vulnerable clinical subgroups. Continued efforts to address these immunisation gaps are needed as a new round of autumn boosting commences.

Improving communication about the human papillomavirus (HPV) vaccination programme among families


What is HPV infographic: a virus that can affect everyone; spread by skin-to-skin contact; usually leaves the body naturally

HPV is a common infection that is spread by skin-to-skin contact, including sexual contact, which can lead to the development of cancers affecting both women and men, including the cervix, vulva, vagina, penis, anus, and oral cavity.

In England, young people aged 12 to 13 years are offered immunisation against HPV as part of the NHS vaccination programme. Research has shown that in England cervical cancer has almost been eliminated among young women who were offered the HPV vaccine. The programme has also been shown to be good value for money for the NHS.

Our research has identified sustained inequalities in uptake by area and minority ethnic groups. Further, we identified unmet information needs among young people in schools where vaccination uptake is low, with implications for obtaining consent and vaccination uptake.

Addressing young people’s information needs

To address information needs among young people, we used co-production research methodologies and the 'person-based approach' to develop a lesson about the HPV vaccine with young people from disadvantaged backgrounds and diverse ethnic groups.

The resources for the EDUCATE lesson include films and exercises to assist learning, along with supporting the delivery of the HPV vaccination programme by providing young people with information and answering questions they may have. It prepares them to be vaccinated at school and helps them make the decision to be vaccinated or not. It is designed to be delivered before the school-based HPV vaccination session begins and can be delivered by different professionals, including teachers and immunisation nurses.

The research team partnered with the Personal, Social, Health and Economic (PSHE) Association and then resource has now been awarded their quality mark. It is available free to download from the PSHE website.

The videos that we co-produced with young people can be found on the HPRU in Behavioural Science and Evaluation website.

The work conducted in collaboration with the Health Protection Research Unit in Behavioural Science & Evaluation, was funded by the Medical Research Council’s (MRC) Public Health Intervention Development (PHIND)  Programme and the Economic and Social Research Council (ESRC) Impact Acceleration Account (IAA).

Improving communication with parents

We are also carrying out a project which aims to co-design an intervention to improve parental confidence, and increase adolescent’s access to, the HPV vaccination programme. As part of this, we have developed a series of films about the HPV vaccine. The content, style and format of the COMMUNICATE films are intended to address vaccine misinformation and were informed by the preferences of vaccine hesitant, ethnically diverse parents.

The videos that we co-designed with vaccine hesitant parents can be found on the HPRU in Behavioural Science and Evaluation website.

The study was conducted in collaboration with the Health Protection Research Unit in Behavioural Science & Evaluation, and funded by the National Institute for Health and Care Research (NIHR) Research for Patient Benefit (RfPB).

Next, we plan to co-design, refine, and implement a communication strategy to support use of the films locally. We will also engage with key players nationally to share learning and explore opportunities for the films to support delivery of the HPV vaccination programme on a wider scale.

How to tackle vaccine misinformation: what works and what doesn't?

A plain English summary of our research article about communication interventions for countering vaccine misinformation was recently published on the NIHR's website.

A diagram showing potential strategies, strategies with mixed results and potentially unhelpful strategies

Communicating the scientific consensus that vaccines are safe and effective, and using humour to dispel vaccine myths, may tackle misinformation effectively. Scare tactics, and failing to acknowledge uncertainty, could be unhelpful. These and other findings come from a review of 34 studies into communication strategies to tackle untruths about vaccines.

New Preprint - Localising Vaccination Services: Qualitative Insights on an Orthodox Jewish Collaboration with Public health during the UK coronavirus Vaccine Programme
Face masks

Our MedRxiv preprint explores how #PublicHealth services can collaborate with community health groups to 'localise' #COVID19 #vaccination & co-deliver services. This approach offers benefits for minority groups with suboptimal #vaccination coverage.

Minority groups in the UK & elsewhere have been disproportionately affected by #COVID19 & are considered less likely to accept available #vaccines. We analyse an attempt to promote & increase #COVID19 vaccination coverage using local community health partners.

A ‘localised’ approach to delivering immunisations can include communication or implementation strategies, but both approaches involve consideration of investment, engagement and coordination, which are not cost-neutral.

Localising vaccination services in collaboration with welfare groups raises opportunities for the on-going Coronavirus Vaccine Programme and other immunisation programmes, and constitutes an opportunity for ethnic and religious minorities to collaborate in safeguarding community health.

People with learning disabilities “extremely vulnerable” to the effects of COVID-19


People with learning disabilities with COVID-19 are five times more likely to be admitted to hospital and eight times more likely to die compared with the general population of England, according to a new study in The BMJ.

Led by the London School of Hygiene & Tropical Medicine (LSHTM) and the University of Oxford, the research found risks were particularly high for those with severe to profound learning disability, Down’s syndrome and cerebral palsy.

The researchers say prompt access to COVID-19 testing and healthcare is warranted for this group, and prioritisation for COVID-19 vaccination and other targeted preventive measures should be considered.

LSHTM Webinar on disabled people in the UK and the impact of COVID-19
An illustration of a COVID-19 particle

The COVID-19 pandemic has fundamentally changed our lives over the last year. Certain groups are affected more than others, both in terms of risk of death and serious illness and as a consequence of living under lockdown and other restrictions. In this seminar, Professors Tom Shakespeare and Hannah Kuper will consider whether the 14 million disabled people in the UK are a particularly impacted group.  

Webinar: Tuesday 27 April 2021 13:00-14:00

Hannah Kuper’s presentation will include a study of the risk of COVID-19 related hospital admission and death among people with learning disability in collaboration with Elizabeth Williamson, HPRU-researcher Helen McDonald, and the OpenSAFELY collaboration. More details of the study are available here. (This is a pre-print which has not been peer-reviewed).

The webinar is free and open to all. No registration is required.

Survey: Frontline health or social care workers in the UK

Are you a frontline health or social care worker in the UK?

We would like to hear about your COVID-19 vaccine views and experiences in our 10-minute survey.

Please click this link for more details and to take part before 8 February 2021:

As COVID-19 has hit minority ethnic groups hardest, we would particularly like to hear the view of health and social care workers from minority ethnic backgrounds.

Your participation will help us identify ways of improving how COVID-19 vaccines are communicated and delivered to health and social care workers.

This research is being conducted by the NIHR Health Protection Research Unit in Immunisation, a research partnership between the London School of Hygiene and Tropical Medicine (LSHTM) and Public Health England, in collaboration with the NHS Race and Health Observatory and the Royal College of Nursing.

Highlights from the NIHR HPRU in Immunisation

Six years of a national immunisation research partnership: highlights from the NIHR HPRU in Immunisation

The National Institute for Health Research (NIHR) Health Protection Research Unit in Immunisation, established in 2014, is a research partnership between the London School of Hygiene & Tropical Medicine and Public Health England. From modelling the role of vaccines in preventing antimicrobial resistance to understanding factors affecting vaccination access amongst underserved communities, the HPRU in Immunisation has conducted wide-ranging research to support the national immunisation programme policy and delivery. 

To celebrate our partnership over the last six years and share the outcomes of our work, we hosted an Open Science event for members of the public and researchers alike on Thursday 12 March 2020. 

The event started with research highlights from the last six years of the HPRU, covering:

  • Theme 1: Electronic Health Record Research 
  • Theme 2: Modelling, Economics, Evidence-synthesis
  • Theme 3: Vaccine Delivery and Confidence
  • Public and Patient Involvement and Engagement  

These highlights were followed by a timely lecture by Professor Mark Jit on "What are LSHTM scientists doing to help us understand and prepare for COVID-19?” with an opportunity for questions afterward.
