What shapes our immune system: our genes or the way we live?
This exciting collaboration with the Snow Centre for Immune Health is investigating why two genetically similar people may respond differently to infections, diseases and treatments.
By recruiting 100 pairs of twins, researchers hope to disentangle the effects of nature and nurture on our immune responses, revealing how much of our immune behaviour is written in our DNA and how much is shaped by our environment and life experiences.

Thanks to our twin members for helping to promote our new study in collaboration with the Snow Centre for Immune Health. Find out more about the study at www.twins.org.au

The findings could revolutionise personalised treatment for everyone.

Thank you to TRA twins, Amanda and Nicole, for helping raise awareness of this important new research into immune health. They themselves live with immune conditions and are encouraging eligible twins to join in "as the insights gained could lead to earlier diagnoses, better treatments and real hope to people like me."

Why do some people respond better to vaccines and treatments?

Co-led by WEHI and The Royal Melbourne Hospital, in partnership with the Snow Medical Research Foundation, the Snow Centre brings together leading Australian and international researchers with a shared mission to transform how we research and treat the immune system.

What a wonderful moment for this Brisbane family - the birth of extremely rare identical quadruplets 😮🙏

Jenitar Sau Na’amoana, 34, was raising four young children and had not planned to have another when she naturally fell pregnant.

A world-first study confirms an innovative procedure is safe and has potential to treat the serious twin pregnancy condition, twin-to-twin transfusion syndrome (TTTS).

Identical twins Nancy and Margo benefitted from the procedure while in the womb as part of a world-first medical trial.

Twin sisters Meaghan and Lauren Clayton share more than careers in paramedicine, they share a passion for creating change for Aboriginal and Torres Strait Islander peoples and communities as part of their work at Ambulance Victoria and Queensland Ambulance Service (QAS).

Proud Kaurna women, Meaghan and Lauren have spent more than a decade serving communities on the frontline while championing cultural safety, health equity and greater representation for First Nations peoples within healthcare.

Through their frontline experience and their involvement in initiatives that support Aboriginal and Torres Strait Islander people, they hope to contribute to culturally responsive care and help create greater opportunities for future generations.

Together, they're not only caring for their communities today, they're passionate about supporting a more inclusive and equitable future for ambulance services across Australia.
