    The question of COVID-19 vaccine acceptance in Sub-Saharan Africa remains of considerable interest as vaccination campaigns are finally underway but vaccination rates are still lagging in most countries in the region.
    Since publishing this paper, we have reported the results from new survey rounds in our High Frequency Phone Surveys (HFPS) series in a blog post. The focus of this new set of results is on vaccine acceptance rates over time. Our surveys in Burkina Faso, Ethiopia, Malawi, Nigeria, and Uganda allowed us to observe the vaccine acceptance of the same respondents once in 2020 and then a second time in 2021. We asked: How stable have the high levels of COVID-19 vaccine acceptance in Sub-Saharan Africa remained between 2020 and 2021?
    We found that overall vaccine acceptance remained high – but with some caveats. In Burkina Faso, Ethiopia, and Nigeria acceptance rates started high at above 75 percent, and then fell by between 1.5 and 6 percentage points over time (Burkina Faso, 2020: 75.7%, 2021: 69.4%; Ethiopia, 2020: 98%, 2021: 96.6%; Nigeria: 2020, 87.5%, 2021: 83.2%). However, these differences are not statistically significant. In contrast, in Malawi, we observed a larger relative drop in acceptance of nine percentage points which was statistically significant (Malawi, 2020: 82.6%, 2021: 73.4%). Finally, in Uganda we observed a statistically significant increase in vaccine acceptance from 84.2% in 2020 to 88.8% in 2021.
