Ep. 73: Improving vaccine messaging

The COVID-19 pandemic highlighted the importance of vaccines, but it also underscored the reservations and low take-up rates among US citizens.

In a paper in the American Economic Journal: Economic Policy, authors Marcella Alsan and Sarah Eichmeyer tested several approaches to improving messages aimed at boosting vaccine demand. Their main finding was that messages delivered by laypersons were more effective than those delivered by persons perceived to be doctors.

Eichmeyer says that video messages delivered by experts who were of the same race or were perceived as empathetic can be effective for some types of viewers, but for the most hesitant, ordinary citizens may be the best positioned to dispel myths about vaccines.

She recently spoke with Tyler Smith about the design of her and Alsan's experiment and what their results imply about vaccine messaging.
