Our analysis of COVID-19 vaccines-related TGA reports shows significant disproportionality.

With an IC025 > 0, COVID-19 vaccines showed a significant ROR (5.1 95%CI 4.4-6.0). Of all TGA cases, 289 were associated with a COVID-19 vaccine, representing the most frequent association. A positive lower end of the 95% CI of the IC (IC025) is used to statistically detect a signal. Disproportionality analysis relied on the Reporting Odds Ratio (ROR) with its 95% Confidence Interval (CI) and the Information Component (IC). We queried the World Health Organization VigiBase ® for all reports of "Transient global amnesia", up to 6 December 2021. We aimed to investigate the potential link of TGA with COVID-19 vaccines. TGA is characterized by sudden onset of anterograde amnesia with preservation of other cognitive functions and resolution within 24 h. As their safety continues to be monitored, cases of transient global amnesia (TGA) following mRNA vaccination with elasomeran have been reported. Coronavirus disease 2019 (COVID-19) spread rapidly, resulting in a global pandemic for which vaccines were quickly developed.
