In order to understand processes and mechanisms that drive and influence the association between misinformation and attitudes toward vaccination, we aim to carry out two reviews to capture the available research evidence on the topic, to understand processes and mechanisms that drive and influence the association between misinformation (intentional and unintentional) and attitudes toward vaccination. Findings will also help us design the next stages of the project.

The first piece of work is a mixed-methods systematic review to evaluate the effectiveness of campaigns / programs on reducing misinformation towards vaccination. The aim is to identify campaigns, programs and interventions that focus on reducing the impact of misinformation on attitudes towards vaccination. The main outcomes of interest are vaccination uptake, attitudes, knowledge, hesitancy, and acceptability. 

The second work stream is a documentary analysis to explore policy strategies on the processes around the spread of misinformation and attitudes towards vaccination. The objective of the review is to identify the policy strategies developed by different institutions and its utility in tackling misinformation and its impact on attitudes towards vaccination. Subsequently, the review aims to synthesize evidence on outcomes around strategies and processes to develop policies to tackle misinformation.
