The Effect of Information From Black Health Care Professionals on COVID Vaccination Take‐Up

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.
