Non-STEM majors COVID-19 vaccine impressions improve, and misconceptions resolve, after podcast assignment

Abstract

Misinformation regarding vaccine science decreased the receptiveness to COVID-19 vaccines, exacerbating the negative effects of the COVID-19 pandemic on society. To mitigate the negative societal impact of the COVID-19 pandemic, impactful and creative science communication was needed, yet little research has explored how to encourage COVID-19 vaccine acceptance and address misconceptions held by non-Science, Technology, Engineering and Mathematics majors (referred to as non-majors). We have previously demonstrated that including expert guest lectures in the vaccine module in the non-major introductory biology course helps combat students' vaccine hesitancy. In the present study, we further address how learning about vaccines impacts student knowledge and impressions of the COVID-19 vaccines through a podcast assignment. As a part of this assignment, non-majors created podcasts to address COVID-19 vaccine misconceptions of their choice. We coded pre and post, open-ended essay reflections (n = 40) to assess non-majors' knowledge and impressions of the COVID-19 vaccines. Non-majors' impressions of the vaccines improved following the podcast assignment with more than three times as many students reporting a positive view of the assignment than negative views. Notably, eight of the nine interviewed students still ended the course with misconceptions about the COVID-19 vaccines, such as the vaccines being unnecessary or causing fertility issues. In a post semi-structured interview following this assignment, students (n = 7) discussed the impact of looking into the specific misconceptions related to COVID-19 vaccines themselves, including improved science communication skills and understanding of different perspectives. Thus, podcasts can provide opportunities for students to improve engagement in valuable societal topics like vaccine literacy in the non-majors classroom.

Impact of podcast activity. Forty students completed both the pre and post-podcast reflections. (A) Students’ general impression of the COVID-19 vaccines as positive, neutral, or negative in the pre-podcast reflections (light blue) and post-podcast reflections (dark blue). (B) Number of students whose impression of the COVID-19 vaccine improved (dark purple), remained unchanged (intermediate purple), or worsened (light purple) from the pre- and post-podcast module. (C) Students’ general impression of the podcast activity as either positive (black) or negative (grey) in the post-podcast reflections.
