![]() Rebounding from the pandemic, while avoiding the lethality and economic costs of repeated waves of infection, requires vaccine development and distribution ( Graham, 2020). ![]() Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected more than 250 million people worldwide, with its resulting Coronavirus disease of 2019 (COVID-19) taking more than five million individuals and counting (as of November 12th, 2021 Center for Systems Science and Engineering at Johns Hopkins University, 2021). COVID-19 vaccination development and distribution These findings thus represent preliminary evidence that naturally circulating memes may-under certain circumstances-influence public intentions to vaccinate, although more research regarding this context-specificity, as well as the potential psychological mechanisms through which memes act, is needed.ġ.1. ![]() These intention-boosting effects, however, weakened once a COVID-19 vaccine became a reality (i.e., after the announcement of a safe/effective vaccine), suggesting meme-based persuasion may be context-dependent. Across two sets of online studies (total n = 1584) conducted in the UK before (August–October 2020) and immediately after the first effective vaccine was publicly announced (November 10–19, 2020), brief exposure (<1 min) to vaccination memes boosted the potentially life-saving intention to vaccinate against COVID-19. Countering such vaccine hesitancy is thus an important priority. Despite global efforts to rapidly distribute COVID-19 vaccines, early estimates suggested that 29–35% of the population were hesitant/unwilling to receive them.
