Economic risk framing increases intention to vaccinate among Republican COVID-19 vaccine refusers.

OBJECTIVE

To determine if framing communications about COVID-19 vaccines in economic terms can increase Republicans' likelihood to get vaccinated.

METHODS

We examined Twitter posts between January 2020 and September 2021 by Democratic and Republican politicians to determine how they framed the COVID-19 pandemic. Based on these posts, we carried out a survey study between September and November 2021 to examine whether motivations for COVID-19 vaccine uptake matched message frames that were widely used by these politicians. Finally, we conducted a randomized controlled experiment to examine how these frames (economic vs. health) affected intentions to vaccinate by vaccine refusers in both parties.

RESULTS

Republican politicians were more likely to frame the pandemic in economic terms, whereas Democrats predominantly used health frames. Accordingly, vaccinated Republicans' choices were more likely to be motivated by economic consideration (β = 0.25, p = 0.02) and personal financial rationales (β = 0.24, p = 0.03). Among vaccine refusers, Republicans exposed to messages using economic rationales to encourage vaccination reported higher vaccination intentions compared to those exposed to messages using public health rationales (F = 4.16, p = 0.04).

CONCLUSION

Messages highlighting economic and personal financial risks could increase intentions to vaccinate for vaccine-hesitant Republicans.

PUBLIC HEALTH IMPLICATIONS

Agencies should invest in developing messages that are congruent with frames that are already widely used by co-partisans. Social media may be helpful in eliciting these frames.
