A pre-test/post-test quasi-experimental study was conducted across six divisions of Ba…
Covid-19 vaccine effectiveness in preventing severe outcomes and assessing the impact of prior Sars-CoV-2 infection among hospitalized adults in Albania, July 2022-July 2023
The COVID-19 pandemic has significantly affected Albania, with over 319959 cases and 3625 deaths by December 2023. Despite a national vaccination campaign initiated in January 2021, only 44.1% of the eligible population had completed the full vaccination regimen by late 2023. In this study, we aim to estimate the effectiveness of COVID-19 vaccines in preventing severe outcomes and in assessing association of prior SARS-CoV-2 infection among adult…
Compliance with the WHO-recommended infant feeding practices among HIV-positive mothers at Public Health Facilities of Mekelle, Tigray, northern Ethiopia
Breastfeeding is crucial for the health of Human Immunodeficiency Virus (HIV)-exposed infants, survival, and development. In the absence of interventions, approximately 10–20% of children can acquire HIV infection during breastfeeding. There is a dearth of studies on this topic, and the findings are inconsistent in the study region. Therefore, the aim of this study is to assess compliance with the World Health Organization (WHO) recommended infan…
Beyond emotions
Understanding the drivers of COVID-19 vaccination intentions remains relevant as public health systems prepare for future pandemics. This study examined how emotional and social-cognitive factors influence COVID-19 vaccination intentions during two key phases of the COVID-19 pandemic: before (April-June 2020) and after (January-February 2021) vaccination rollout. A total of 586 adults completed an online survey assessing beliefs about COVID-19, s…
Integration of Covid-19 testing into existing ILI surveillance system in Ghana
The similarities between the presentations of Influenza-Like Illness (ILI) and COVID-19, generated calls for the integration of COVID-19 surveillance into the existing ILI surveillance system. The aim was to optimize outcomes through efficient use of resources. Ghana responded to the World Health Organization call to integrate the two systems. We share the processes undertaken to integrate SARS-CoV-2 into the ILI surveillance system in Ghana. Sta…
Routine childhood immunization coverage, timeliness, dropout, and missed opportunities in Northern Ghana
Routine childhood immunization plays a crucial role in reducing vaccine-preventable diseases and child mortality. However, sustained progress requires not only high coverage but also timely administration, continuity across multi-dose schedules, and minimization of missed opportunities for vaccination. Persistent subnational inequities, post-COVID-19 disruptions, and gaps in service delivery threaten progress toward Immunization Agenda 2030 targe…
Perceived shifts in routine vaccine confidence during the Covid-19 pandemic in Kinshasa Province, DRC
The COVID-19 pandemic negatively impacted routine immunizations worldwide, decreasing confidence in vaccination programs. We used mixed methods to examine changes in vaccine confidence from before to during the pandemic in HBV-negative adults in Kinshasa who were exposed to HBV in the household, and eligible for HBV vaccination. We measured changes in routine HBV vaccine confidence with a previously validated Shift in Vaccine Confidence (SVC) sel…

Perceptions of respiratory tract infections and their implications for disease prevention practices among older adults in Mysuru, India
Respiratory tract infections (RTIs) remain an important cause of mortality and morbidity, particularly among older adults. Annual influenza epidemics cause around 127,000 deaths in India of which 65% are among adults of 65 years and older. Because of India’s rapidly growing older adult population, RTIs are likely to become an even greater public health issue and implementing effective preventive strategies will be crucial. To inform pharmaceutica…
Determinants of Covid-19 vaccine hesitancy among healthcare personnel in a secondary-level health facility in Ghana
Vaccine hesitancy has been a long-standing concern globally and emerged during the COVID-19 pandemic among healthcare personnel. This study assessed the prevalence and determinants of vaccine hesitancy among healthcare personnel at the Volta Regional Hospital in Ghana. A cross-sectional study was conducted among 419 randomly selected healthcare personnel to collect sociodemographic, individual-level, community-level, and health system-level data,…
Pathways and processes to adopting or switching to a single-dose HPV vaccination schedule in low- and middle-income countries
The World Health Organization (WHO) recently endorsed a single-dose human papillomavirus vaccination (HPVV) schedule, but adoption of the revised immunization schedule has not been uniform, notably in low- and middle-income countries (LMICs) with outsized cervical cancer burdens. We sought to characterize the sequence of events, as well as actors/institutions involved, that facilitate or impede country-level decision-making related to the HPVV sc…
Qualitative and quantitative evaluation of hand hygiene knowledge, attitudes, and practices among healthcare workers in Quetzaltenango, Guatemala in the Covid-19 context
Healthcare workers and patients are at continual risk for healthcare-associated infections due to poor hand hygiene. Programs that support appropriate hand hygiene practices may mitigate this risk, although implementation is challenged by several barriers, including limited availability of hand hygiene products at the point of care, as described by the world health organization (WHO). In this study, we used mixed methodologies, including in-depth…
Change in influenza vaccine uptake among adults in the United States from May 2020 to October 2024
Influenza vaccines are essential against the spread of influenza virus. In the United States, the Centers for Disease Control and Prevention (CDC) recommends vaccination to all eligible individuals over 6 months of age; however, uptake remains suboptimal nationally. We do not fully understand the current nuances of influenza vaccine uptake, nor how it has been affected by the coronavirus disease 2019 (COVID-19) pandemic. From 2020-2024, we conduc…
Is health, growth and development impaired in children who are Hepatitis B-exposed but uninfected
An estimated 254 million people are living with chronic hepatitis B virus (HBV) infection worldwide. Many infants are born to mothers with HBV but do not themselves acquire the infection. It is unclear whether this exposure to HBV in early life - without the development of active infection - may be associated with adverse outcomes. We propose the term “HBV-exposed uninfected (HBEU)”, drawing parallels with the HIV field which recognises that chil…
Longitudinal association between parents’ reported vaccination program preferences and children’s actual immunization patterns in Shanghai, China
There were no associations between parents' reported preference categories and children's vaccination patterns. The high acceptance of combination vaccines and tolerance of co-administration gives parents choices for vaccination and impart increased confidence in including new vaccines in the vaccination program
Associations between extreme weather events and child undernutrition
BACKGROUND: Extreme weather events, or natural disasters, present a large and increasing threat to human health, infrastructure and food security, including in sub-Saharan Africa (SSA), where the burden of undernutrition is high.

Parents were asked about their acceptance of a COVID-19 vaccine for their children, and if the…
Uptake and cardiac events of Covid-19 vaccinations among Canadian youth and young adults
Few studies have examined population-level data of the COVID-19 original and bivalent vaccine on its uptake and potential side effects. We used population-based health administrative data from Jan 2021–Feb 2023 to identify Ontario residents aged 12–35 years old to calculate their rates of COVID-19 vaccine uptake and vaccine-related cardiac events (myocarditis and pericarditis). Multivariable Cox, logistic, and negative binomial regression analyse…
Moral foundations messaging to improve vaccine attitudes
The uptake of routine childhood vaccinations has declined globally since the start of the COVID-19 pandemic, due in part to increased vaccine hesitancy among parents. The Moral Foundations Theory proposes six foundations which can be targeted to increase vaccine uptake. In this study, we tested whether a post by UNICEF with a purity violation message could affect vaccine attitudes among parents in Argentina, where routine immunization coverage ha…
Impact of vaccination education in cardiac rehabilitation on attitudes and knowledge
Clinical guidelines recommend influenza vaccination for cardiac patients, and COVID-19 vaccination is also beneficial given their increased risk. Patient education regarding vaccination was developed for cardiac rehabilitation (CR); impact on knowledge and attitudes were evaluated.

This cross-sectional study utilised both quantit…
Data-driven scenario-based model projections and management of the May 2021 Covid-19 resurgence in India
The resurgence of the May 2021 COVID-19 wave in India not only pointed to the explosive speed with which SARS-CoV-2 can spread in vulnerable populations if unchecked, but also to the gross misreading of the status of the pandemic when decisions to reopen the economy were made in March 2021. In this combined modelling and scenario-based analysis, we isolated the population and policy-related factors underlying the May 2021 viral resurgence by proj…
Estimates of the number and distribution of zero-dose and under-immunised children across remote-rural, urban, and conflict-affected settings in low and middle-income countries
While there has been great success in increasing the coverage of new childhood vaccines globally, expanding routine immunization to reliably reach all children and communities has proven more challenging in many low- and middle-income countries. Achieving this requires vaccination strategies and interventions that identify and target those unvaccinated, guided by the most current and detailed data regarding their size and spatial distribution. Th…

Modeling the relative risk of incidence and mortality of select vaccine-preventable diseases by wealth group and geographic region in Ethiopia
Immunization is one of the most effective public health interventions, saving millions of lives every year. Ethiopia has seen gradual improvements in immunization coverage and access to child health care services; however, inequalities in child mortality across wealth quintiles and regions remain persistent. We model the relative distributional incidence and mortality of four vaccine-preventable diseases (VPDs) (rotavirus diarrhea, human papillom…
A study of Covid-19 vaccination in the US and Asia
The COVID-19 pandemic presents an opportunity to assess the relationship between personal experiences and vaccine decision-making. The aim of this study was to examine the associations between experiences with COVID-19 and COVID-19 vaccination status. We administered 28 repeated cross-sectional, online surveys between June 2020 and June 2021 in the US and Asia. The main exposure was media showing COVID-19 cases, and we distinguished those with no…
Hesitancy towards Covid-19 vaccination
There is an increased need for COVID-19 vaccination since the world is gradually returning to normal. Current evidence supports vaccination activity more towards viral suppression than COVID-19 prevention. This has led to divergent views regarding vaccination which may influence anti-vaccine attitudes and vaccine hesitancy. The study examined the role of personality traits, anti-vaccine attitudes and illness perceptions on vaccine hesitancy. The …
Adverse events following Covid-19 vaccination in Kwara State, North-central Nigeria
Safe and effective vaccination remains the mainstay of control of COVID-19 because there is still no universally recommended treatment. This strategy is however being threatened by vaccine hesitancy and resistance due to fear of adverse events and safety concerns. It is, therefore, necessary to study post-vaccination adverse events (AE) in various populations and geographical areas. The objective of this study was to analyze the adverse events fo…
Factors associated with receipt of a timely infant birth dose of hepatitis B vaccine at a tertiary hospital in North-Central Nigeria
The World Health Organization recommends universal vaccination of medically stable infants with Hepatitis B vaccine within 24 hours of birth to prevent mother-to-child transmission of Hepatitis B virus (HBV) infection. However, the proportion of infants who receive a timely birth dose is extremely low in Nigeria. We reviewed the implementation of an infant HBV vaccine schedule at a single center and identified factors affecting the receipt of a t…
Perceived Severity of Covid-19 in a Longitudinal Study in Detroit, Michigan
Our findings suggested that perceived severity for COVID-19 decreased through time and was affected by different factors among varied racial/ethnic groups.

Validation of the Vaccination Trust Indicator (VTI) in a multi-country survey of adult vaccination attitudes
Improved uptake of adult vaccinations could substantially reduce the burden of infectious disease worldwide, however very few countries achieve high coverage of recommended adult vaccinations. Vaccine hesitancy is an important driver of low vaccine uptake among adults but no measure currently exists to capture general vaccination attitudes in this population accurately and efficiently. We utilize data from two surveys of adult vaccine attitudes a…
Persuasive Covid-19 vaccination campaigns on Facebook and nationwide vaccination coverage in Ukraine, India, and Pakistan
Social media platforms have a wide and influential reach, and as such provide an opportunity to increase vaccine uptake. To date, there is no large-scale, robust evidence on the offline effects of online messaging campaigns. We aimed to test whether pre-tested, persuasive messaging campaigns from UNICEF, disseminated on Facebook, influenced COVID-19 vaccine uptake in Ukraine, India, and Pakistan. In Ukraine, we deployed a stepped-wedge randomized…
Rotavirus genotypes in children under five years hospitalized with diarrhea in low and middle-income countries
Rotavirus is the most common pathogen causing pediatric diarrhea and an important cause of morbidity and mortality in low- and middle-income countries. Previous evidence suggests that the introduction of rotavirus vaccines in national immunization schedules resulted in dramatic declines in disease burden but may also be changing the rotavirus genetic landscape and driving the emergence of new genotypes. We report genotype data of more than 16,000…
Determining the rate of infectious disease testing through contagion potential
The emergence of new strains, varying in transmissibility, virulence, and presentation, makes the existing epidemiological statistics an inadequate representation of COVID-19 contagion. Asymptomatic individuals continue to act as carriers for the elderly and immunocompromised, making the timing and extent of vaccination and testing extremely critical in curbing contagion. In our earlier work, we proposed contagion potential (CP) as a measure of t…
