Many people are hesitant or unwilling to take advantage of potentially life-saving vaccines; this is true even in a global pandemic and even when vaccines are readily available and/or free. Apart from general unwillingness to be vaccinated, fear of side effects is a frequently named reason for vaccine hesitation. This survey-based study, carried out online in Austria in March of 2021, examines the efficacy of two different approaches – framing and nudging – in promoting a fictional COVID-19 vaccine program. While nudging had no visible effects, either positive or negative, framing was associated with more positive feelings toward the campaign and a greater intention to be vaccinated, though only among those already pre-disposed to get the vaccine. Governments and healthcare organizations are eager to find low-cost measures to increase vaccination rates for COVID-19 and other diseases. This study’s results suggest that addressing and positively framing the high likelihood of problem-free vaccinations should form an integral part of public messages, but that this approach may be ineffective among those who are strongly hesitant or unwilling.
