Although the use of the cluster randomized trial (CRT) design to evaluate vaccines, public health interventions or health systems is increasing, the ethical issues posed by the design are not adequately addressed, especially in low- and middle-income country settings (LMICs). To help reveal ethical challenges, qualitative interviews were conducted…

Research has shown a mixed relationship between education and vaccination rates. In the current analysis, we aimed to determine the relationship between educational level and coronavirus disease 2019 (COVID-19) vaccination rates. We performed a cross-country analysis on data from 133 countries. Correlation analyses showed that higher and better…

This research brief is one of a series of six briefs, which provide an overview of available evidence shown in the Campbell-UNICEF Mega-Map of the effectiveness of interventions to improve child well-being in low- and middle-income countries. Five of these briefs summarize evidence as mapped against the five goal areas of UNICEF's 2018-2021…

Interest and motivation significantly influence achievement; however, interest in immunology remains to be determined. Using a structured questionnaire, the current study assessed for the first time interest in immunology among biomedical graduate students in Ghana after a one-week introduction to immunology course. Our results revealed that…

Studies on developed countries demonstrate that an increase in women legislators leads to a prioritization in health, an increase in social policy spending, and a decrease in poverty. Women representatives could therefore improve development trajectories in developing countries; yet, currently, no cross-national and longitudinal studies explore…

Enormous strides have been made in reducing the number of global under-five child deaths through expanded development and use of vaccines under the auspices of the GAVI Alliance. However such successes have left behind a significant burden of child morbidity and mortality in developing countries from six major tropical diseases, i.e., dengue,…

Background: The dominant theoretical basis of our public health practice originates from a positivist or reductionist paradigm. It fails to take into account the complexity emerging out of public health's multiple influences originating from biological and social worlds. A deeper understanding of the interaction of elements that characterize the…

This dissertation presents the results of three field experiments implemented to evaluate the effectiveness of strategies to improve the health or education of children in developing countries. In Guatemala, community health workers at randomly selected clinics were given patient tracking lists to improve their ability to remind parents when their…

Although it is well known that vaccines against many infectious diseases confer positive economic externalities via indirect protection, analysts have typically ignored possible herd protection effects in policy analyses of vaccination programs. Despite a growing literature on the economic theory of vaccine externalities and several innovative…
