The COVID-19 infodemic as a major driver for vaccine hesitancy in conflict settings: a mixed-method study

Abstract

AbstractSince COVID-19 emerged in China, social media has spread fake news and conspiracy theories faster than the virus, causing the population to take false actions and follow misleading information, which leads to hospitalization, and even deaths, especially in conflict settings. Therefore, efforts to address health misinformation on social media have become urgent. For these reasons, we monitored social media following the vaccine rollout in Yemen and assessed the impact of the infodemic on the population's vaccine hesitancy in Yemen. To triangulate our data, we executed a mixed method approach in which qualitative data via online social listening was gathered using the WHO Early AI-supported Response with Social Listening (EARS) platform, and then complemented and verified with a Knowledge, Attitude and Practices (KAP) survey. Our results showed that social media in Yemen were exhibited contradictory facts and information gaps about the COVID-19 vaccine. The unaddressed questions and concerns on Facebook and Twitter have been filled with all types of misinformation, including rumors and conspiracy theories about the vaccine. Furthermore, the government's weak Risk Communication and Community Engagement (RCCE) have caused an enormous mistrust in its public health actions and stimulated negative behaviours towards the COVID-19 vaccine. The online social listening results were complemented with the survey findings as one third (38%) of the respondents admitted that COVID-19 vaccine misinformation affected their health decisions and almost two-third (61%) showed unwillingness to take the COVID-19 vaccine which clearly demonstrate the Yemenis hesitation in making health decisions including vaccine uptake. Our study highlights the importance of strengthening health communication and infodemic management to mitigate vaccine hesitancy and increase public confidence in the COVID-19 vaccine.
