Millions of
lives have been impacted by the COVID-19 pandemic (World Health Organization
[WHO], 2021). However, scientific knowledge on how to effectively respond to
COVID-19 outbreaks has also increased considerably in a very short time (Weiner
at al., 2020). For example, several research teams have developed promising
COVID-19 vaccines, and, as of April 2021, about 732 million vaccination doses have
been administered worldwide (WHO, 2021). Further success in reducing the
COVID-19 burden relies on the public’s awareness and acceptance of scientific
knowledge. Health communication plays an essential role in the complex
relationship between scientific knowledge and individuals’ beliefs and
behaviours. However, attempts by health communicators to inform and educate
individuals about the characteristics of the disease and effective prevention
measures compete with persuasive mis- and disinformation, especially online
(Lewandowsky et al., 2021). Studies reveal that misinformation about COVID-19
undermines trust in institutions (Pummerer et al., 2020), decreases willingness
to undertake effective prevention measures such as vaccination (Loomba et al.,
2021) and adds to the overabundance of (mis-)information that makes it
difficult for individuals to find trustworthy sources – an overabundance known
as an infodemic (WHO, 2020). That is, mis- and disinformation pose major
challenges for health communication around the globe.
To master
these challenges and prepare for future public health crises, it is vital to
understand mis- and disinformation surrounding COVID-19. What kinds of mis- and
disinformation do individuals encounter off- and online? What impact do these
have on cognition, emotions, attitudes and behaviours? Which groups are
specifically susceptible to mis- and disinformation, and how can theory-based
interventions be designed to combat mis- and disinformation surrounding
COVID-19?
