As global distribution of COVID-19 vaccine expands, the Brighton Collaboration has identified a subset of adverse events of special interest (AESIs) for low- and middle-income countries (LMICs) to prioritize in their enhanced safety surveillance. The core AESIs are categorized in two tiers; most Tier One AESIs would be hospitalized and can be included in hospital-based sentinel site surveillance, whereas Tier Two and can be assessed in cohort event monitoring or outpatient settings.
See Below the most recent version (Vo.9, June 17,2021) of the draft list of core AESIs.
