The Effect of Information From Black Health Care Professionals on COVID Vaccination Take‐Up
通过实验发现，由黑人医疗专业人员提供疫苗安全性和有效性信息，5个月后整体接种率提高8个百分点（17%），其中白人参与者提高9.8个百分点（24%），政治倾向是重要调节因素。
This study experimentally tests the impact of providing information about vaccine safety and efficacy delivered by Black health care professionals. We find that providing general information increases vaccination rates after 5 months by 8 percentage points (17%), driven by a 9.8 pp (24%) increase among white participants. Political affiliation emerges as a key moderator to explain this discordant effect. Across race, general information is more effective for politically moderate and conservative respondents, most of whom are white. Among this most vaccine-hesitant group, the information effectively addresses concerns about both side effects and unknown long-run effects due to the fast approval of the vaccine, increasing vaccination rates by 14 pp.
