Active surveillance
The World Health Organization defined active surveillance as the collection of case study information as a conitnuous pre-organized process (The importance of pharmacovigilance).
CIOMS distinguished three types of Active surveillance:
1. drug based: identifying adverse events in patients taking pharmaceutical products,
2. setting based: identifying adverse events in certain health care settings where patients are likely to present for treatment (e.g., emergency departments, etc.), or
3. event based: identifying adverse events that are likely to be associated with medical products (e.g. acute liver failure).

Results of Literature Review and Survey of COVID-19 Vaccine Safety Assessment Activities
In 2021, there was an urgent need to support the COVAX Vaccine Safety Working Group (VSWG), the Coalition for Epidemic Preparedness Innovations (CEPI), and the WHO-Pharmacovigilance team (WHO-PV) in collating the studies evaluating the safety of COVID-19 vaccines globally to inform strategy and policy. A landscape assessment of COVID-19 vaccine safety surveillance activities, including a literature review and a survey, was conducted to inform on potential sources of evidence and to identify gaps: VH Safety Maps.
