The unprecedented attempt to achieve widescale vaccine coverage, however, has been met with an onslaught of false and misleading information. Misinformation has the potential to adversely affect vaccine uptake. For example, almost 40% of Americans now say they would not get the vaccine and a recent study found that belief in COVID-19 misinformation significantly reduced willingness to get the vaccine. Accordingly, it is critical to ramp up defenses against the on-going wave of COVID-19 vaccine misinformation and utilize effective strategies aimed at curbing its influence.
