COVID-19 Vaccine Preferences in China: A Comparison of Discrete Choice Experiment and Profile Case Best-Worst Scaling.

ABSTRACT:

Objectives

Little is known about the diversity of residents' preferences for COVID-19 vaccines during the time when COVID-19 management was downgraded in China. This study aims to investigate these preferences using discrete choice experiment (DCE) and profile case best-worst scaling (BWS-2), and to assess the concordance between these two methods.

Methods

Chinese residents recruited for the online survey were asked to evaluate COVID-19 vaccine profiles through both DCE and BWS-2 from April to July 2023. Attributes included effectiveness, duration of protection, risk of severe adverse events (degree), the total out-of-pocket (OOP) cost, brand, and the vaccination method. We utilized conditional regression and mixed logit regression models to estimate the preference levels fo
