Background Rates of Adverse events for Vaccine Evaluation in Africa (BRAVE)

The BRAVE project* will develop infrastructure for post-authorisation vaccine safety surveillance in low- and middle-income countries (LMICs) and identify the rates of potential adverse events of special interest (AESI) before the introduction of new vaccines. Surveillance of the rates of the same AESI in a similar population after a vaccine is introduced and comparison of these ‘observed rates’ with the ‘background rates’ may identify potential vaccine safety signals that require further investigation.

VAERS misuse: The zombie practice that keeps coming back

Helen Petousis-Harris, BSc, PGDipSci (Dist), PhD

Today’s episode: The one about the strokes after COVID-19 vaccine. An unscientific study misusing Vaccine Adverse Event Reporting System (VAERS) data has arisen from the crypt. The study jumps to alarming conclusions and even calls for a global halt on COVID-19 vaccines. Conspiracy theorists on social media snapped up the authors' dramatic claims and exaggerated risk with sensational figures. As in so many cases of deliberate generation of disinformation, this baloney has gone viral.
