It is a pleasure to invite you to participate in the ASCIA 2020 Conference, the 31st annual conference of the Australasian Society of Clinical Immunology and Allergy (ASCIA), in Melbourne, Victoria. The ASCIA 2020 Conference will run for 3 days, from Wednesday 2nd to Friday 4th September 2020, and will be held at the Melbourne Convention Centre. This includes concurrent sessions for Nurses, Dietitians and Medical Associate ASCIA members on Friday 4th September 2020. The conference will be held in conjunction with the Centre for Food & Allergy Research (CFAR) Symposium on Tuesday 1st September 2020 and the ANZVASC Symposium on Saturday 5th September 2020. ASCIA annual conferences provide an international standard of continuing professional development and a unique opportunity to interact and collaborate with colleagues. These events are therefore a highlight of the year for ASCIA members and other health professionals working allergy, clinical immunology and immunopathology.
