Trends in Adverse Event Reporting Before and After the Introduction of the Med Safety App in Nigeria.

Introduction: Spontaneous reporting of adverse events (AEs) is a mainstay of pharmacovigilance, and an ongoing challenge is how to ensure that more high-quality reports are collected for comprehensive information provision. The Med Safety App, a smartphone-based application, was launched in Nigeria in November 2020 to provide an electronic platform for users to seamlessly report AEs. There has been a paucity of evidence on the use of this application or other mobile applications for reporting adverse drug reactions/AEs following immunization in the Nigerian environment.

Background: Adverse drug reactions (ADRs) are a source of concern in healthcare as they negatively affect patients. Serious adverse drug reactions (SADRs) have an even greater impact on patients and the system in terms of morbidity and financial burden. The establishment of National Pharmacovigilance Centers (NPCs) has enhanced ADR reporting in Africa.
