Background/Purpose: The COVID-19 outbreak created unique policy challenges for vaccinating special groups like migrants. As part of sustainable development goals, the equitable distribution of the COVID-19 vaccine can contribute to ensuring health for all. This study examined COVID-19 vaccine uptake among foreign migrants in China based on sociodemographics, cultural beliefs, past vaccine behaviors, and psychosocial factors. Design: An online cross-sectional survey was conducted among foreign migrants in mainland China via social media platforms from 21 November through 20 December 2021.

Result: Surveyed foreign migrants that are culture neutral (AOR: 2.5, CI: 95%, 1.02–5.90, p = 0.044), willing to pay for vaccination (AOR: 2.27, CI: 95%, 1.18–3.98, p = 0.012), believe in vaccine efficacy (AOR: 3.00, CI: 95%, 1.75–5.16, p
