The role of adverse event follow-up in advancing the knowledge of medicines and vaccines safety: a scoping review

The primary objective of this scoping review is to understand and evaluate the concept, implementation, frequency, and value of “follow-up” in the context of adverse event (AE) assessment. Secondary objectives include providing an overview of various definitions of “follow-up,” describing the requirements and studies evaluating follow-up methods, and assessing how often follow-up is undertaken in assessing an AE, by whom, and its value.
