    Abstract: Routine immunization coverage estimated in surveys often substantially differs from figures reported in administrative records, presenting a dilemma for researchers and policy makers. Using high-frequency phone surveys and administrative records from government sources in 36 low- and middle-income countries, this paper shows that such misalignment has also been common in the case of COVID-19. Across the sample, survey estimates exceed administrative figures by 47 percent on average, at times suggesting markedly different policy conclusions depending on the data source consulted. This pattern is particularly stark and consistent in Sub-Saharan Africa. To investigate the sources of this discrepancy, the paper presents results from six methodological experiments that vary survey design choices and documents their effect on estimated COVID-19 vaccine coverage. The results show that design choices matter, in particular the selection of respondents to be interviewed. However, phone survey estimates prove remarkably robust to several commonly claimed biases. After accounting for observed errors of representation and measurement in the survey data, there remains a nonnegligible, unexplained residual gap with administrative records. The paper provides indicative evidence of flaws and weaknesses in administrative data recording and reporting that affect reported vaccination rates and could contribute to this gap. The findings matter for past research on COVID-19 vaccination, future immunization efforts, and the design of robust data production systems on health topics

    Abstract: Recent debates surrounding the lagging COVID-19 vaccination campaigns in low-income countries center around vaccine supply and financing. Yet, relatively little is known about attitudes toward COVID-19 vaccines in these countries and in Africa in particular. This paper provides cross-country comparable estimates of the willingness to accept a COVID-19 vaccine in six Sub-Saharan African countries. It uses data from six national high-frequency phone surveys in countries representing 38 percent of the Sub-Saharan African population (Burkina Faso, Ethiopia, Malawi, Mali, Nigeria, and Uganda). Samples were drawn from large, nationally representative sampling frames providing a rich set of demographic and socioeconomic characteristics which are used to disaggregate the analysis. The findings show acceptance rates to be generally high, with at least four in five people willing to be vaccinated in all but one country. Vaccine acceptance ranges from nearly universal in Ethiopia (97.9 percent) to below what would likely be required for herd immunity in Mali (64.5 percent). Safety concerns about the vaccine in general and its side effects emerge as the primary reservations toward a COVID-19 vaccine across countries. These findings suggest that limited supply, not inadequate demand, likely presents the key bottleneck to reaching high COVID-19 vaccine coverage in Sub-Saharan Africa

    Abstract: Every year, disasters account for billions of dollars in crop production losses in low- and middle-income countries and particularly threaten the lives and livelihoods of those depending on agriculture. With climate change accelerating, this burden will likely increase in the future and accurate, micro-level measurement of crop losses will be important to understand disasters' implications for livelihoods, prevent humanitarian crises, and build future resilience. Survey data present a large, rich, highly disaggregated information source that is trialed and tested to the specifications of smallholder agriculture common in low- and middle-income countries. However, to tap into this potential, a thorough understanding of and robust methodology for measuring disaster crop production losses in survey microdata is essential. This paper exploits plot-level panel data for almost 20,000 plots on 8,000 farms in three Sub-Saharan African countries with information on harvest, input use, and different proxies of losses; household and community-level data; as well data from other sources such as crop cutting and survey experiments, to provide new insights into the reliability of survey-based crop loss estimates and their attribution to disasters. The paper concludes with concrete recommendations for methodology and survey design and identifies key avenues for further research

    The Evolution of COVID-19 Vaccine Hesitancy in Sub-Saharan Africa : Evidence from Panel Survey Data (2023)

    Abstract: COVID-19 vaccination rates in Sub-Saharan Africa lag behind other world regions, with just over 20 percent of the population in Sub-Saharan Africa fully vaccinated. To reach widespread coverage, high willingness to get vaccinated for COVID-19 among the population is considered an important prerequisite. Drawing on two years of panel survey data, this paper studies the dynamics of vaccine acceptance, its correlates, and reasons for hesitancy over time. The data come from multiple rounds of national High-Frequency Phone Surveys in five countries in East and West Africa (Burkina Faso, Ethiopia, Malawi, Nigeria, and Uganda), covering the period between 2020 and 2022. The surveys are cross-country comparable and draw their samples from nationally representative sampling frames. The paper finds that COVID-19 vaccine acceptance has been high throughout the study period (68 to 98 percent). However, acceptance levels were lower in 2022 than in 2020 in three countries (Burkina Faso, Malawi, and Nigeria) and higher in one country (Uganda). Moreover, individuals are observed to change their stated vaccine attitudes between survey rounds, to a limited extent in some countries (Ethiopia) and more frequently in others (Burkina Faso, Malawi, Nigeria, and Uganda). Vaccine hesitancy is higher in richer households and among those residing in urban areas, women, and the better educated. Conversely, hesitancy is lower in larger households and among heads of the household. The main reasons for hesitancy are concerns about side effects of the vaccine, its safety and efficacy, as well as assessments of COVID-19 risk, although these reasons fluctuate over time. The findings suggest that vaccine hesitancy is not the primary obstacle to reaching greater vaccine coverage in Sub-Saharan Africa. Instead, low coverage rates may be related to access and delivery barriers as well as supply shortages. Nevertheless, vaccine attitudes appear malleable so that continued efforts are needed to retain high levels of vaccine acceptance

    The Impacts of Disasters on African Agriculture : New Evidence from Micro-Data (2024)

    Abstract: Disasters affect millions of people each year and cause economic losses worth many billions of dollars globally. Reporting on disaster impacts in research, policy, and news primarily relies on macro statistics based on disaster inventories. The macro statistics suggest that a relatively small share of disaster damages accrues in Africa. This paper, instead, uses detailed survey micro-data from six African countries to quantify disaster damages in one key sector: crop agriculture. The micro-data reveals much higher damages and more people affected than the macro statistics would indicate. On average, 36 percent of the agricultural plots in the sample suffer crop losses due to adverse climatic events. In the countries and time period analyzed, these losses reduced total crop production by an average of 29 percent. Importantly, many of these losses are underreported or undetected in key disaster inventories and therefore elude macro statistics. In the case of droughts and floods, the economic losses recorded in the micro-data are USD 5.1 billion higher than in the macro statistics, affecting 145 million to 170 million people, more than four times as many as the macro statistics suggest. The difference stems mostly from smaller and less severe but frequent adverse events that are not recorded in disaster inventories

    Keywords: Access To Vaccine ; COVID-19 ; Immunizations ; Intrahousehold Power Relations ; Public Health Promotion ; Vaccination ; Vaccine Acceptance ; Vaccine Hesitancy ; Health, Nutrition and Population
    Abstract: As COVID-19 vaccines have become more widely available in Sub-Saharan Africa, vaccination campaigns in the region have struggled to pick up pace and trail the rest of the world. This paper presents new evidence on vaccine hesitancy, uptake, last-mile delivery barriers, and potential strategies to reach those who remain unvaccinated. The data come from high-frequency phone surveys in five countries in East and West Africa (Burkina Faso, Kenya, Malawi, Nigeria, and Tanzania). The surveys were conducted by countries' national statistical agencies, have national scope, are cross-country comparable, and draw their samples from nationally representative sampling frames. The findings show that across the study countries, a majority is willing to get vaccinated. Still, vaccine hesitancy is non-negligible among those pending vaccination. Concerns about side effects of the vaccine are the primary reason for hesitancy. At the same time, many who are willing to get vaccinated are deterred by a lack of easy access to vaccines at the local level. Radio broadcasts have widespread reach and medical professionals have good rapport among the unvaccinated population. Furthermore, social ties and perceptions as well as intrahousehold power relations matter for vaccine take-up. Based on the findings, the paper elaborates policy options to boost vaccination campaigns in Sub-Saharan Africa
