TraX mpox data report: Report period 10 Oct 2022 to 21 Apr 2024

This report summarises data collected as part of the TraX study from its launch on 10 October 2022 to 21 April 2024. Survey data were collected weekly on rates of mpox vaccine uptake, mpox infection, and sexual behaviours among people considered at high risk of mpox infection in Australia. Unless otherwise stated, data included in this report are from participants who provided at least one follow-up survey.

Key findings

During this reporting period, 2,893 people across Australia participated in the TraX study and provided at least one follow-up response.

Throughout the study, monthly rates of testing for mpox remained consistent at approximately 1.0%.

Among the 2,893 participants, based on the latest survey responses provided by participants, by 21 April 2024, the proportion reporting themselves as unvaccinated against mpox has decreased by more than half to 9.2%, leaving 265 participants unvaccinated. The proportion who reported having received only one mpox vaccination also fell to 10.5% (N=305), and the proportion who had received both mpox vaccinations increased to 80.3% (N=2323).
