Queensland COVID-19 Vaccination Safety and Efficacy Trial (QoVAX SET)

April 12, 2022

The QoVAX SET Statewide Study aims to better understand the short, medium and long-term impacts of COVID-19 and COVID-19 vaccines in Queensland. This includes understanding how and why people’s immune systems respond differently to COVID-19 vaccines.

This study will help health services to make decisions about ongoing vaccine programs and to plan for more people needing treatment for the COVID-19 virus. The Queensland Health program team are looking for participants to take part in the study.

Eligible participants are people who:

  • have had at least two doses of a COVID-19 vaccine with the last dose received one to three months ago
  • are 18 years old or over and a Queensland resident.

Participants will need to complete a survey and may be asked to provide a blood sample. If you have any questions, contact the QoVAX SET Program Team at or call 07 3647 1064.
