This electronic tool will help analysts conduct a causality assessment of AEFI, both online (on computers) and offline (on tablets and iPads).
An AEFI is any untoward medical occurrence (sign, abnormal laboratory finding, symptom, or illness) which follows immunization and which does not necessarily have a causal relationship with the vaccination process or the vaccine itself.
A Causality assessment attempts to establish the level of certainty that the vaccine or the vaccination process was the origin or cause of the clinical picture and of the symptoms or signs observed in the vaccinated individual.
