Objective: To evaluate the impact of equity-focused community-engagement initiatives on the uptake of five routine childhood vaccinations. Design: Quasi-experimental study within a synthetic control analysis framework. Setting: Primary care in England between April 2019 and March 2025. Childhood vaccination data were obtained from the Cover of Vaccination Evaluated Rapidly (COVER) programme. Intervention: The Health Equity Liverpool Project (HELP) is a community-engagement vaccination initiative implemented between October 2023 and June 2024 across nine sites in central and north Liverpool. Activities were co-developed with local partners and delivered in neighbourhoods with persistently low childhood vaccine coverage. Intervention practices were defined as those located within 1 km of HELP delivery sites (n=19). A weighted combination of non-intervention practices across England (n=5826) was used to construct a synthetic control group. Main outcomes: Quarterly counts of vaccinated children following intervention implementation for first doses of the measles, mumps and rubella vaccine (MMR1 at 24 months and at 5 years), second dose of MMR (MMR2 at 5 years), pneumococcal conjugate vaccine (PCV at 24 months), the 6-in-1 vaccine, covering diphtheria, tetanus, pertussis, polio, haemophilus influenzae type b, and hepatitis B (at 12 months), and the rotavirus vaccine (at 12 months). Results: Following HELP, rotavirus vaccine uptake increased by 10.03% (95% CI 0.37% to 24.63%), corresponding to 120 (95% CI 4 to 295) additional infants vaccinated in the intervention group compared to the synthetic control. Similarly, 6-in-1 vaccine uptake rose by 11.56% (95% CI 2.37% to 25.56% ∼143 95% CI 29 to 317 additional children vaccinated. No statistically significant changes were observed for MMR1, MMR2, or PCV. Improvements were short-lived, with uptakes returning to pre-intervention levels after approximately nine months. Conclusions: Community-engagement vaccination interventions may produce a modest short-term improvement in uptake of selected early life vaccines but show limited evidence of benefit for MMR uptake. Our findings suggest that such approaches are unlikely to have a sustained impact without long-term investment, integration into existing immunisation systems and addressing the wider social determinants of health. What is already known on this topic?: Childhood vaccination rates in England have declined over the last decade and inequalities in uptake are persistent andwidening. Children in socioeconomically deprived areas are less likely to receive routine vaccinations, reflecting both structural barriers and vaccine hesitancy driven by misinformation and lack of trust. Innovative community engagement interventions are recommended to address these inequalities, yet evidence of their effectiveness remains limited. What this study adds?: Our study shows that hyperlocal community engagement interventions can increase uptake of early-life infant vaccines (rotavirus and 6-in-1) by around 10-12% but provides limited evidence of similar improvements for the MMR vaccine. The observed improvements in infant vaccines were transient, returning to baseline levels after approximately nine months, suggesting that one-off initiatives may not produce sustained public health gains without tackling wider social determinants of health.

Objective: To assess the contribution of changing child poverty rates to trends in measles, mumps and rubella (MMR) vaccination. Design: Longitudinal area-level analysis using within-between models to assess the association of increases in child poverty within-areas on MMR vaccination Setting: 148 upper-tier local authorities in England from 2015 and 2024. Participants: Children aged 5 years or younger eligible for MMR vaccination in England between 2015 and 2024. 6,468,620 children aged 24 months were included in the study and 6,907,640 aged 5 years. Exposures: Child poverty rates for each upper-tier local authority, measured as the percentage of children aged 0 to 15 living in households below 60% of Organisation for Economic Co-operation and Development (OECD) median, before housing costs. Outcome Measures: MMR 1 ^st and 2 ^nd dose uptake rates by 24 months 5 years of age respectively, at upper-tier local authority. Results: Over the study period, MMR 1 ^st dose fell by 4.0 percentage-points (%) (range: −20.8 to 7.7) and MMR 2 ^nd dose by 4.9% (range: −23.4 to 10.1) while child poverty rose by 5.6% (range: 0.2 to 13.9) on average. A 1 percentage-point (%) increase in child poverty was associated with a 0.17% [95%CI: −0.29; −0.06] fall in MMR 1 ^st dose rates and a 0.26% [95%CI: −0.42; −0.10] fall in MMR 2 ^nd dose rates. Conclusion: Rising child poverty rates have contributed to a decrease in MMR vaccination in children in England. Action to reduce child poverty is needed to improve childhood vaccination uptake alongside policies and interventions specific to vaccination and infectious disease prevention. Summary box: What is already known on this topic: Inequalities in childhood vaccination uptake in England are stark and have widened, especially for MMR vaccination. Child poverty in England has increased and is associated with rising inequalities in multiple domains of children’s health but impacts on inequalities in vaccination uptake are unclear. What this study adds: A 1 percentage-point increase in child poverty was associated with a 0.17 percentage point fall in uptake of MMR1 and a 0.26 percentage point fall in MMR2 between 2015 and 2024. Reducing child poverty is likely to increase vaccine uptake and reduce the burden of vaccine preventable diseases in England.

Background: The presence of multiple medical chronic conditions is a growing burden across Africa, where people experience a double burden of communicable and non-communicable diseases (NCD). Integrated chronic disease care at the primary healthcare level is a means to improve person-centred care for people living with multimorbidity. This study aimed to assess public primary healthcare facilities’ service availability and readiness to manage multimorbidity in Malawi, through the lens of HIV, type 2 diabetes, hypertension and chronic kidney disease. We explored healthcare workers’ perceptions of their capacity to provide care for individuals with multimorbidity and the availability of services and resources at their facility. Methods: We conducted a mixed-methods health facility cross-sectional study in primary healthcare facilities in Blantyre and Chiradzulu districts, Malawi. We used the modified WHO Service Availability and Readiness Assessment Tool to assess 12 facilities, and conducted in-depth interviews with 12 purposively selected health facility leads. Availability is presented as the proportion of facilities offering each service. Facility readiness is defined as the mean(percentage) availability of 44 tracer items with a cutoff point of ≥70%, classified as ‘ready’ to manage multimorbidity. Readiness score for individual conditions was also calculated based on the availability of tracer items of that condition with a cutoff point of ≥70%. Results: Of the surveyed facilities, 83%(10/12) offered services for all four selected conditions. Only 30%(3/10) of all facilities had a readiness score of ≥70%, indicative of minimum service delivery requirements for multimorbidity were met. The mean readiness score for type 2 diabetes (65.7%) was the highest, followed by HIV (63.8%), hypertension (60.4%), and chronic kidney disease had the lowest readiness score (22.9%). Barriers to service readiness included nonfunctional diagnostic equipment, frequent drug stockouts and insufficient staffing and supervision, and a lack of clinical guidelines or protocols. Conclusion: The assessed sites were inadequately prepared to provide integrated care for chronic kidney disease, type 2 diabetes, HIV and hypertension. The ability to provide integrated screening and management will require functional diagnostic equipment and consistent drugs. Periodic quality assurance and combined multimorbidity audits could further highlight the gaps in service delivery and give clues to improvement.

Background: Stigma, lack of trust in authorities, and poor knowledge can prevent health-seeking behaviour, worsen physical and mental health, and undermine efforts to control transmission during disease outbreaks. These factors are particularly salient with diseases such as mpox, for which 96% of cases in the 2022–2023 UK outbreak were identified among gay, bisexual, queer and men who have sex with men (MSM). This study explored stigma and health-seeking behaviour in Liverpool through the lens of the recent mpox outbreak. Methods: Primary sources of data were interviews with national and regional key informants involved in the mpox response, and participatory workshops with priority populations. Workshop recruitment targeted Grindr users (geosocial dating/hookup app) and at risk MSM; immigrant, black and ethnic minority MSM; and male sex workers in Liverpool. Data were analysed using a deductive framework approach, building on the Health Stigma and Discrimination Framework. Results: Key informant interviews (n = 11) and five workshops (n = 15) were conducted. There were prevalent reports of anticipated and experienced stigma due to mpox public health messaging alongside high demand and uptake of the mpox vaccine and regular attendance at sexual health clinics. Respondents believed the limited impact of stigma on health-seeking behaviour was due to actions by the LGBTQ + community, the third sector, and local sexual health clinics. Key informants from the LGBTQ + community and primary healthcare felt their collective action to tackle mpox was undermined by central public health authorities citing under-resourcing; a reliance on goodwill; poor communication; and tokenistic engagement. Mpox communication was further challenged by a lack of evidence on disease transmission and risk. This challenge was exacerbated by the impact of the COVID-19 pandemic on the scientific community, public perceptions of infectious disease, and trust in public health authorities. Conclusions: The LGBTQ + community and local sexual health clinics took crucial actions to counter stigma and support health seeking behaviour during the 2022–2023 UK mpox outbreak. Lessons from rights based and inclusive community-led approaches during outbreaks should be heeded in the UK, working towards more meaningful and timely collaboration between affected communities, primary healthcare, and regional and national public health authorities.

Background The prevalence of multimorbidity (the presence of two or more chronic health conditions) is rapidly increasing in sub–Saharan Africa. Hospital care pathways that focus on single presenting complaints do not address this pressing problem. This has the potential to precipitate frequent hospital readmissions, increase health system and out-of-pocket expenses, and may lead to premature disability and death. We aim to present a description of inpatient multimorbidity in a multicentre prospective cohort study in Malawi and Tanzania. Primary objectives Determine prevalence of multimorbid disease among adult medical admissions and measure patient outcomes. Health Economic: Measure economic costs incurred and changes in health-related quality of life (HRQoL) at 90 days post-admission. Situation analysis: Qualitatively describe pathways of patients with multimorbidity through the health system. Secondary objectives Determine hospital readmission free survival and markers of disease control 90 days after admission. Health Economic: Present economic costs from patient and health system perspective, sub-analyse costs and HRQoL according to presence of different diseases. Situation analysis: Understand health literacy related to their own diseases and experience of care for patients with multimorbidity and their caregivers. Methods This is a prospective longitudinal cohort study of adult (≥18 years) acute medical hospital admissions with nested health economic and situation analysis in four hospitals: 1) Queen Elizabeth Central Hospital, Blantyre, Malawi; 2) Chiradzulu District Hospital, Malawi; 3) Hai District Hospital, Boma Ng’ombe, Tanzania; 4) Muhimbili National Hospital, Dar-es-Salaam, Tanzania. Follow-up duration will be 90 days from hospital admission. We will use consecutive recruitment within 24 hours of emergency presentation and stratified recruitment across four sites. We will use point-of-care tests to refine estimates of disease pathology. We will conduct qualitative interviews with patients, caregivers, healthcare providers and policymakers; focus group discussions with patients and caregivers, and observations of hospital care pathways.

Nosocomial infections threaten patient safety, and were widely reported during the COVID-19 pandemic. Effective hospital infection control requires a detailed understanding of the role of different transmission pathways, yet these are poorly quantified. Using patient and staff data from a large UK hospital, we demonstrate a method to infer unobserved epidemiological event times efficiently and disentangle the infectious pressure dynamics by ward. A stochastic individual-level, continuous-time state-transition model was constructed to model transmission of SARS-CoV-2, incorporating a dynamic staff–patient contact network as time-varying parameters. A Metropolis–Hastings Markov chain Monte Carlo (MCMC) algorithm was used to estimate transmission rate parameters associated with each possible source of infection, and the unobserved infection and recovery times. We found that the total infectious pressure exerted on an individual in a ward varied over time, as did the primary source of transmission. There was marked heterogeneity between wards; each ward experienced unique infectious pressure over time. Hospital infection control should consider the role of between-ward movement of staff as a key infectious source of nosocomial infection for SARS-CoV-2. With further development, this method could be implemented routinely for real-time monitoring of nosocomial transmission and to evaluate interventions.

Safeguarding challenges in global health research include sexual abuse and exploitation, physical and psychological abuse, financial exploitation and neglect. Intersecting individual identities (such as gender and age) shape vulnerability to risk. Adolescents, who are widely included in sexual and reproductive health research, may be particularly vulnerable. Sensitive topics like teenage pregnancy may lead to multiple risks. We explored potential safeguarding risks and mitigation strategies when studying teenage pregnancies in informal urban settlements in Nairobi, Kenya. Risk mapping was initiated by the research team that had prolonged engagement with adolescent girls and teen mothers. The team mapped potential safeguarding risks for both research participants and research staff due to, and unrelated to, the research activity. Mitigation measures were agreed for each risk. The draft risk map was validated by community members and coresearchers in a workshop. During implementation, safeguarding risks emerged across the risk map areas and are presented as case studies. Risks to the girls included intimate partner violence because of a phone provided by the study; male participants faced potential disclosure of their perceived criminal activity (impregnating teenage girls); and researchers faced psychological and physical risks due to the nature of the research. These cases shed further light on safeguarding as a key priority area for research ethics and implementation. Our experience illustrates the importance of mapping safeguarding risks and strengthening safeguarding measures throughout the research lifecycle. We recommend co-developing and continuously updating a safeguarding map to enhance safety, equity and trust between the participants, community and researchers.
