SARS-CoV-2 Breakthrough Infections among US Embassy Staff Members, Uganda, May-June 2021

Julie R Harris et al. Emerg Infect Dis. 2022 Jun.

Abstract

The SARS-CoV-2 Delta variant emerged shortly after COVID-19 vaccines became available in 2021. We describe SARS-CoV-2 breakthrough infections in a highly vaccinated, well-monitored US Embassy community in Kampala, Uganda. Defining breakthrough infection rates in highly vaccinated populations can help determine public health messaging, guidance, and policy globally.

Keywords: COVID-19; SARS; SARS-CoV-2; US Embassy; Uganda; breakthrough; coronavirus; coronavirus disease; respiratory infections; severe acute respiratory syndrome coronavirus 2; vaccine; viruses; zoonoses.
