This study examines the effect of the country of origin of the vaccine on vaccination acceptance against COVID-19. More specifically, we show how the political context in Brazil has affected acceptance of vaccines produced in China, Russia, the US, and England at the University of Oxford. Our data come from a survey experiment applied to a national sample of 2771 adult Brazilians between September 23 and October 2, 2020. We find greater rejection among Brazilians for vaccines developed in China and Russia, as compared to vaccines from the US or England. We also find that rejection of the Chinese-developed vaccine is particularly strong among those who support President Jair Bolsonaro-a COVID-19 denier and strong critic of China and vaccination, in general.
本研究考察了疫苗原产国对 COVID-19 疫苗接种接受度的影响。更具体地说，我们展示了巴西的政治环境如何影响了对中国、俄罗斯、美国和英国牛津大学生产的疫苗的接受度。我们的数据来自于一项针对 2020 年 9 月 23 日至 10 月 2 日期间全国 2771 名成年巴西人的调查实验。我们发现，与来自美国或英国的疫苗相比，巴西人对中国和俄罗斯开发的疫苗的拒绝率更高。我们还发现，在中国开发的疫苗中，那些支持总统贾尔·博索纳罗（COVID-19 否认者，以及对中国和疫苗的强烈批评者）的人对该疫苗的拒绝率尤其高。
