These data provide you with a profile of what to expect in the days following your child's Pfizer COVID-19 vaccination and can assist when planning for your child's COVID-19 vaccination. The profile of reported events from AusVaxSafety surveillance of the Pfizer (Comirnaty) COVID-19 vaccine is similar to that reported in clinical trials and from post-marketing surveillance overseas. AusVaxSafety's active vaccine safety surveillance system complements the enhanced safety surveillance activities of the Therapeutic Goods Administration (TGA). 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.
