Systematic vaccine safety surveillance is indispensable in ensuring public trust of the Expanded Program on Immunisation (EPI) and quality of vaccines. The hospital-based sentinel surveillance system (HBSSS) was designed to detect safety signals of rare adverse events of special interest (AESl) or to evaluate safety signals arising from other sources, following vaccination with COVID-19 vaccines in Uganda. The evaluation aimed to assess the impact and feasibility of HBSSS as a vaccine safety surveillance model for low- and middle-income countries.
