Supported by the Living Standards Measurement Study (LSMS) program and the Global Financing Facility (GFF)

For three years since the start of the COVID-19 pandemic, phone survey data has been critical for policy research on vaccine access, attitudes and take-up. Meanwhile, there are debates about the limits to reliability and suitability of phone surveys to collect data on vaccinations and other health outcomes.

In this seminar, you will get insights from more than two years of cross-country research on COVID-19 vaccination in Sub-Saharan Africa, based on high-frequency phone surveys from six countries supported by the Living Standards Measurement Study (LSMS) program. We will also explore the reliability and suitability of the phone surveys for collecting vaccination data, considering discrepancies between survey-based estimates and administrative records, draw lessons for phone survey implementation and methodology, and discuss the operational implications of their findings.
