ABSTRACT
This report summarises Australian spontaneous surveillance data for adverse events following immunisation (AEFI) for 2020, reported to the Therapeutic Goods Administration (TGA), and describes reporting trends over the 21-year period from 1 January 2000 to 31 December 2020. There were 3,827 AEFI records for vaccines administered in 2020, an annual AEFI reporting rate of 14.9 per 100,000 population. There was a slight (3.8%) decrease in the overall AEFI reporting rate in 2020 compared with 2019 (15.5 per 100,000 population). This decrease in the AEFI reporting rate in 2020 is potentially due to the impact of coronavirus disease 2019 (COVID-19) and was mainly from a decline in reported adverse events related to HPV, dTpa, and seasonal influenza vaccines. AEFI reporting rates for most individual vaccines in 2020 were similar to 2019. The most commonly reported adverse events were injection site reaction (37.1%); pyrexia (18.1%); rash (15.8%); vomiting (7.6%); pain (7.4%); headache (5.7%); and urticaria (5.1%). There were six deaths reported to the TGA. In one of the reports, the timing and clinical findings were consistent with a causal association with vaccination. In the remaining five reports, no clear causal relationship with vaccination was found.
