Effectiveness and impact of the 2-component acellular pertussis vaccine as a preschool booster in Finland – A register-based study
In 2005, Finland replaced the whole-cell pertussis (wP) 3 + 1 schedule with an acellular pertussis (aP) 2 + 1 infant schedule supplemented by a DTaP-IPV preschool booster at age 4 in the National Immunization Program (NIP). Recent pertussis resurgence and uncertainty about the duration of vaccine-induced protection have raised concerns. We assessed the effectiveness, duration of protection and population-level impact of the preschool booster. We …
Prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae infections and associated risk factors among pregnant women and key populations in Kenya
Sexually-transmitted pathogens Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) cause curable but often asymptomatic bacterial infections. Missed diagnoses and treatment, leading to chronic infections, can cause clinical complications and increase transmission. Accurate prevalence estimates are essential for the effective public health control of these sexually transmitted infections, especially in Africa, where data are scarce. This cro…
Maternal microchimerism at birth associates with reduced odds of non-malarial fever and respiratory tract infections in Tanzanian children
The presence of maternal cells in the offspring at birth, a phenomenon known as maternal microchimerism, has been previously associated with decreased odds of malaria and respiratory infections in early childhood suggesting a role in immunological responses to infections. Here, we assess the effect of cord blood maternal microchimerism on symptomatic non-malarial infections in Tanzanian children. We conducted a secondary analysis using a nested b…
Hyper-Local, Place-Based Strategies to Increase PrEP Uptake Among Black Sexual Minority Men in Alabama
We describe a community–academic pilot to strengthen pre-exposure prophylaxis (PrEP) outreach for Black sexual minority men (BSMM) in Birmingham, Alabama, using hyper-local, place-based digital advertising delivered in two micro-settings. Brief formative interviews with BSMM and local consensus discussions with a trusted community partner informed two tailored advertisements. Using platform metrics and routine program data, we assessed feasibilit…
Coverage and contextual factors associated with insecticide-treated net use among women of reproductive age in Nigeria
Nigeria continues to face a serious public health problem due to malaria, which contributes around 27% of all cases worldwide. Although insecticide-treated nets (ITNs) are essential interventions for preventing malaria, their use in Nigeria is still sub-optimal. Understanding the factors influencing ITN use is essential to improve malaria control strategies. This study aimed to investigate the prevalence of and factors associated with ITN use amo…
Improving training on hepatitis B research in Nigeria
We organized an Innovation Bootcamp for young people in Nigeria to develop strategies promoting the uptake of the hepatitis B birth dose vaccine among newborns, which remains low, with an estimated coverage of 52%. This event was a collaborative, cross-disciplinary capacity-building platform to generate creative solutions addressing barriers to Hepatitis B vaccine uptake. The purpose of this study was to describe the bootcamp activities that addr…
Community-level determinants of RTS,S/AS01 vaccine acceptance in a hyperendemic Ghanaian Region
The successful scale-up of Ghana’s RTS,S/AS01 malaria vaccine depends on understanding community-level variation in caregiver acceptance. This study investigates vaccine acceptance and its predictors in a hyperendemic municipality bordering Volta Lake, where geographic and contextual disparities may hinder equitable implementation. A weighted, community-based cross-sectional survey was conducted from November 2023 to January 2024 among 452 caregi…
Lifetime homelessness among young transgender women in Lima, Peru is associated with HIV vulnerability
Transgender youth face disproportionately high rates of homelessness, which can increase vulnerability to HIV. In Peru, the incidence of HIV among transgender women has increased 19% since 2010 and young transgender women are a priority population for HIV prevention. We sought to estimate the proportion of young transgender women experiencing homelessness and associations between homelessness and HIV vulnerabilities. We recruited transgender wome…
A latent class analyses of economic stability, medical mistrust, and barriers to care in relation to PrEP awareness in Black communities in Miami, FL
In the U.S., Black communities are disproportionately impacted by HIV due to economic instability, racism, and structural inequities. Among Black residents who participated in a bundled implementation study from November 2019 through March 2020 in HIV high impact communities in Miami, FL this study examines (a) which latent classes are most prevalent based on indicators of economic stability (ES; income, work, housing, zip-code poverty thresholds…
Oferta de PrEP em organizações comunitárias
OBJETIVO: Avaliar se adolescentes de minorias sexuais que iniciaram a profilaxia pré-exposição sexual (PrEP) em organizações comunitárias (OC) apresentam maior vulnerabilidade social e ao HIV em comparação com adolescentes em PrEP de um serviço de saúde convencional. Além disso, avaliar se esses adolescentes tiveram um acesso mais oportuno à profilaxia. MÉTODO: Estudo demonstrativo da efetividade de PrEP, realizado na cidade de São Paulo, em duas…

Race/Ethnicity Differences in Covid-19 Vaccine Uptake Among Nurses
INTRODUCTION: There is evidence for relatively lower COVID-19 vaccine uptake among people of color in the United States. The purpose of this study was to investigate associations between race/ethnicity and COVID-19 vaccine uptake among nurses. METHODS: = 1183) completed a one-time, web-based survey to assess COVID-19 vaccine perceptions and uptake. RESULTS: = 979) received at least one COVID-19 vaccine dose. Identifying as East Asian was associat…

Investigating the nature of competition facing private healthcare facilities
The private healthcare sector in low- and middle-income countries is increasingly seen as of public health importance, with widespread interest in improving private provider engagement. However, there is relatively little literature providing an in-depth understanding of the operation of private providers. We conducted a mixed methods analysis of the nature of competition faced by private delivery providers in Uttar Pradesh, India, where maternal…
