Misinformation in COVID-19: Strategies for policy makers to mitigate its effects

< Back to IPPO

Start Date: 1st April 2022

End Date: 12th December 2022

The COVID-19 (C-19) pandemic has been generating unprecedented quantities of misinformation and pseudoscientific facts that influence people’s behaviour in ways that severely undermine public health mitigation strategies. National and local policymakers have expressed to us their concerns about C-19 misinformation and challenges they have experienced in attempting to counter it. 

To identify, characterise and synthesise accumulating research knowledge about C-19 misinformation in order to provide decision-makers with evidence they need to help tackle the spread and impacts of misinformation in the C-19 and future public health emergencies.

Key Components
This project has two components. A living map of research evidence on misinformation in COVID-19, followed by a rapid evidence review of selected strategies (interventions) for countering misinformation and its spread:

  1. Living evidence map: A regularly updated map comprising bibliographic records of published articles reporting empirical research studies on misinformation in COVID-19, organised by topic and other selected study characteristics. 
  2. Rapid evidence review: A rapid evidence review summarising evidence from published research studies that have addressed the question: When is debunking misinformation about vaccines likely to be a better option than either providing accurate information only, or not responding, for reducing people’s vaccine-related misinformation beliefs or vaccine hesitancy, changing people’s attitudes to vaccines, and/or increasing people’s intentions to be vaccinated or vaccine uptake?

Stakeholder Engagement
We continue to engage with various stakeholders (primarily in the UK) to inform the development of this project. This has helped us to identify, formulate and refine a specific research question and methods for the rapid evidence review; and it will also help us to refine key messages and implications for practice, policy and research based on its findings.

Further information will be posted on this page as we continue to develop this project. For enquiries about this work, please contact Ian Shemilt ( or James Thomas (
