Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed.

Confidence, Acceptance and Willingness to Pay for the COVID-19 Vaccine Among Migrants in Shanghai, China: A Cross-Sectional Study
21 Pages Posted: 27 Jan 2021More...
Background: Vaccine hesitancy became one of the top ten threats to global health. This study aimed to assess the acceptance and willingness to pay (WTP) for COVID-19 vaccine among migrants in Shanghai, China.
Methods: A cross-sectional study was conducted among 2,126 migrants in Shanghai during November 1-20th, 2020. A questionnaire was used to measure confidence in, acceptance of and WTP for COVID-19 vaccine. Multivariable (ordered) logistic regressions were used to examine factors associated with acceptance and WTP of COVID-19 vaccine.
Findings: Most (89.1%) migrants stated that they would accept COVID-19 vaccination. Over 90.0% migrants perceived COVID-19 vaccine as important, while only 75.0% and 77.7% perceived vaccines safe and effective. Socio-demographic factors were not significantly associated with vaccine acceptance, but confidence in the importance, safety and effectiveness of COVID-19 vaccine was significantly associated with vaccine acceptance. The top reasons for vaccine hesitancy were lack of vaccine information and confidence. Proportion of those definitely willing to get COVID-19 vaccine was 20% lower if paid by themselves than free vaccination. Migrants were willing to pay a median amount of US$ 46 for COVID-19 vaccine.
Interpretation: A high acceptance of COVID-19 vaccine was universal among migrants in Shanghai, China. Concerns about vaccine safety and effectiveness as well as high costs of the COVID-19 vaccine may hinder their uptake in the future. Effective health communication to build confidence in the COVID-19 vaccine and subsidies toward the prohibitive costs of these vaccines are needed to improve uptake.
