TraX mpox data report: Report period 10 Oct 2022 to 1 Jan 2023

This report summarises data collected during the first three months the TraX Study (10 October 2022 – 1 January 2023). Data are collected weekly on MPOX (formerly monkeypox) vaccine uptake, infection, and sexual behaviours among people considered at high risk of infection in Australia.

Key findings
  • 2445 people across Australia participated in the TraX study during the reporting period. Most participants were from New South Wales (83.1%).
  • At study entry, 24.7% of participants reported being unvaccinated against MPOX, 47.2% had received one MPOX vaccination, and 28.1% had received two MPOX vaccinations.
  • At study entry, nine participants reported a prior incidence of MPOX infection.
  • No new cases of MPOX were reported during the study period, precluding any calculations on vaccine effectiveness.
