Key Points

  • This research aims to assess the effectiveness of COVID-19 vaccines in preventing hospitalizations due to COVID-19-associated severe acute respiratory infections (SARI) in Ghana.
  • Analyzed hospital data for COVID-19-associated SARI cases from June 2022 to March 2024
  • Focused on laboratory-confirmed cases of SARS-CoV-2
  • Evaluated vaccine effectiveness in reducing hospitalizations
  • COVID-19 vaccines were found to prevent SARI hospitalizations in the initial 6 months of the study period
  • A protective effect was observed, consistent with findings from other regions
  • Effect estimates, however, were noted to be imprecise

Abstract

COVID-19 vaccines may have prevented COVID-19-associated SARI hospitalizations in the first 6 months over the study period in Ghana, and a pattern of protective effective was observed, consistent with report from other settings, although effect estimates were imprecise.
