*During 2021, young people and people working in hotel quarantine programmes emerged as groups with high COVID-19 incidence, so additional seed sets were added to the recruitment target. Recruitment targets for people who spoke AMD as their preferred language were added in response to concern about stigma towards African and Chinese communities and lack of culturally appropriate information.
