Data on this page show the responses of all individuals received the Moderna bivalent BA.1 or BA.4/5 COVID-19 vaccine and completed an AusVaxSafety survey sent on day 3 after vaccination. Note: The Moderna bivalent BA.1 and BA.4/5 COVID-19 vaccines are no longer being administered in Australia; therefore, Moderna bivalent BA.1 and BA.4/5 COVID-19 vaccine safety data below are no longer updated. AusVaxSafety has retained the display of historical Moderna BA.1 and BA.4/5 COVID-19 vaccine safety data as a reference.

AusVaxSafety's active vaccine safety surveillance system complements the TGA's enhanced safety surveillance activities. Find out more about how the TGA monitors the safety of COVID-19 vaccines and how you can report side effects on the TGA website.
