Estimating the historical impact of outbreak response immunisation programmes across 210 outbreaks in low and middle-income countries
BACKGROUND: Outbreaks of vaccine-preventable diseases frequently occur in low and middle-income countries (LMICs), requiring outbreak response immunisation (ORI) programmes for containment. To inform future investment decisions, this study aimed to estimate the cases, deaths, disability-adjusted life years (DALYs) and societal economic costs averted by past ORI programmes. Outbreaks of measles, Ebola, yellow fever, cholera and meningococcal menin…
Can unvaccinated children be reached through mobile phones? Analyses of national cross-sectional surveys from 70 countries
Background: Interventions using mobile phones, otherwise known as mHealth interventions, are increasingly being used in low- and middle-income countries to remind families about scheduled child immunisations. Despite this, few studies examined impact on zero-dose children - those who failed to receive a single dose of a routine vaccine. As disparities in mobile phone ownership may limit the effectiveness of mHealth interventions, we assessed asso…
The impact Covid-19 pandemic on coverage and inequalities in childhood immunization in Peru
The COVID-19 pandemic temporarily disrupted Peru's childhood immunization efforts, particularly affecting poorer populations, but coverage rebounded to pre-pandemic levels by 2022. These findings contribute to the scant literature on the pandemic's impact on vaccine equity
Inequalities in ownership and availability of home-based vaccination records in 82 low- and middle-income countries
INTRODUCTION: Home-based records (HBRs) are widely used for recording health information including child immunisations. We studied levels and inequalities in HBR ownership in low-income and middle-income countries (LMICs) using data from national surveys conducted since 2010. METHODS: We used data from national household surveys (Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS)) from 82 LMICs. 465 060 children ag…
Zero-dose children and the extended immunisation cascade
Background: As part of the Immunisation Agenda 2030, the World Health Organization set a goal to reduce the number of children who did not receive any routine vaccine by 50% by 2030. We aimed to describe the patterns of vaccines received for children with zero, one, and up to full vaccination, while considering newly deployed vaccines (pneumococcal conjugate vaccine (PCV) and rotavirus (ROTA) vaccine) alongside longstanding ones such as the Bacil…
Exploring the “Urban Advantage” in Access to Immunization Services
Urban children are more likely to be vaccinated than rural children, but that advantage is not evenly distributed. Children living in poor urban areas face unique challenges, living far from health facilities and with lower-quality health services, which can impact their access to life-saving vaccines. Our goal was to compare the prevalence of zero-dose children in poor and non-poor urban and rural areas of low- and middle-income countries (LMICs…
Religious affiliation as a driver of immunization coverage
Background: The literature on the association between religion and immunization coverage is scant, mostly consisting of single-country studies. Analyses in low and middle-income countries (LMICs) to assess whether the proportions of zero-dose children vary according to religion remains necessary to better understand non-socioeconomic immunization barriers and to inform interventions that target zero-dose children. Methods: We included 66 LMICs wi…
Ethnic disparities in immunisation
Background The Sustainable Development Goals (SDGs) recommend stratification of health indicators by ethnic group, yet there are few studies that have assessed if there are ethnic disparities in childhood immunisation in low-income and middle-income countries (LMICs). Methods We identified 64 LMICs with standardised national surveys carried out since 2010, which provided information on ethnicity or a proxy variable and on vaccine coverage; 339 et…
Children of more empowered women are less likely to be left without vaccination in low- and middle-income countries
Background: To help provide a global understanding of the role of gender-related barriers to vaccination, we have used a broad measure of women's empowerment and explored its association with the prevalence of zero-dose children aged 12-23 months across many low- and middle-income countries, using data from standardized national household surveys. Methods: We used data from Demographic and Health Surveys (DHS) of 50 countries with information on …
Overcoming Obstacles to Peace
In the past decade, RAND has published a series of studies on nationbuilding. We intend this term to describe operations conducted by external civilian and military authorities that employ armed force alongside other means of influence in the aftermath of conflict to promote enduring peace. Some prefer the term state-building, giving primacy to postconflict activities aimed at constructing state institutions and deemphasizing those activities int…
Prospects for Democratization in the Arab World
Daunting challenges lie ahead for countries undergoing political transitions in the Arab world. Researchers identify the challenges these countries face and suggest policy approaches that may help foster enduring democracies
Democratization in the Arab World
Daunting challenges lie ahead for Arab countries where revolutions have upended longstanding authoritarian regimes. This monograph aims to help policymakers understand the challenges ahead, form well-founded expectations, shape diplomatic approaches, and take practical steps to foster positive change
