Widespread misperceptions about COVID-19 and the novel coronavirus threaten to exacerbate the severity of the pandemic. We conducted preregistered survey experiments in the United States, Great Britain and Canada examining the effectiveness of fact-checks that seek to correct these false or unsupported beliefs. Across three countries with differing levels of political conflict over the pandemic response, we demonstrate that fact-checks reduce targeted misperceptions, especially among the groups… 
COVID-19 Vaccine Fact-Checking Posts on Facebook: Observational Study
COVID-19 fact-checking vaccine posts from hospitals yielded more positive attitudes toward vaccination than other information sources, and hospitals received less engagement than other Information sources, which suggests that hospitals should invest more in generating engaging public health campaigns on social media.

Knowledge and Behaviours towards Immunisation Programmes: Vaccine Hesitancy during the COVID-19 Pandemic Era
Monitoring this trend by studying people’s behaviour and attitudes could be a useful tool to aid Public Health, in orienting vaccination policies and designing new health education and continuous training interventions, aimed at both the general public and accountable cohorts, such as HCWs.

Beliefs About COVID-19 in Canada, the United Kingdom, and the United States: A Novel Test of Political Polarization and Motivated Reasoning

The research that is reviewed suggests that the accuracy-increasing effects of corrective information like fact checks often do not last or accumulate; instead, they frequently seem to decay or be overwhelmed by cues from elites and the media promoting more congenial but less accurate claims.
The causes and consequences of COVID-19 misperceptions: Understanding the role of news and social media

The role of race, religion, and partisanship in misperceptions about COVID-19
It is found that minorities, those with high levels of religiosity, and those with strong partisan identities – across parties – hold a substantially greater number of misperceptions than those with contrasting group affiliations.
Knowledge does not protect against illusory truth.
Contrary to prior suppositions, illusory truth effects occurred even when participants knew better, andMultinomial modeling demonstrated that participants sometimes rely on fluency even if knowledge is also available to them, demonstrating knowledge neglect, or the failure to rely on stored knowledge, in the face of fluent processing experiences.

The effects of corrective information about disease epidemics and outbreaks: Evidence from Zika and yellow fever in Brazil
Investigation of interventions aimed at combating false and unsupported information about the Zika epidemic and subsequent yellow fever outbreak in Brazil finds that corrective information not only fails to reduce targeted Zika misperceptions but also reduces the accuracy of other beliefs about the disease.
