Confronting 'chaos': a qualitative study assessing public health officials' perceptions of the factors affecting Tanzania's COVID-19 vaccine rollout.

Objectives: Mass COVID-19 vaccination in Africa is required to end the pandemic. In low-income settings, street-level bureaucrats (SLBs), or public officials who interact directly with citizens, are typically responsible for carrying out vaccination plans and earning community confidence in vaccines. The study interviewed SLBs to assess their perceptions of the factors affecting COVID-19 vaccination rollout in Tanzania.
