Factors associated with COVID-19 vaccine uptake among foreign migrants in China

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. Bivariate (unadjusted odd-ratio) and multivariate logistic regression analyses were performed to establish the correlates of COVID-19 vaccine uptake. 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 < 0.000), have poor psychological health (AOR: 1.96, CI: 95%, 1.14–3.38, p = 0 0.014), and have higher perceived seriousness of COVID-19 (AOR: 2.12, CI: 95%, 1.26–3.57, p = 0.005) are more likely to receive COVID-19 vaccine. Those migrants with a history of declining vaccination (AOR: 0.34, CI: 95%, 0.18–0.65, p = 0.000) and middle-income earners $1701–3500 (AOR: 0.43, CI: 95%, 0.23–0.82, p = 0.010) are less likely to receive the COVID-19 vaccine. CONCLUSION: This study brings a unique perspective to understanding vaccine behavior among international migrants in China. There is an urgent call from the World Health Organization and countries for complete vaccination and efforts to improve vaccine coverage. However, fewer studies have been conducted globally on the vaccination of migrant populations. The current study provides empirical information to increase the knowledge of the correlates of vaccine behavior among immigrants in countries around the globe. Future studies should conduct cross-country comparisons to understand the factors associated with increasing vaccination rates among immigrant populations to formulate a strong policy to increase vaccine coverage among immigrant populations across countries.
