Effect of a social media-based counselling intervention in countering fake news on COVID-19 vaccine in Nigeria

Abstract

Summary The aim of this study was to understand the impact of counselling in countering fake news-related COVID-19 vaccine. We conducted two separate experiments. In the first experiment, we exposed the treatment group to fake news on COVID-19 vaccine through a WhatsApp group chat while the control group was not. We then tested the effectiveness of such fake news on their perception. In our second experiment, we exposed the treatment group to a social media-based counselling intervention wherein we attempted to counter the earlier fake news on COVID-19 vaccine which they were exposed to. We found that respondents who were exposed to fake news reported greater negative perception about COVID-19 vaccine than their counterparts in the control group. We also we found that as a result of the counselling intervention, the respondents in the treatment group reported more positive perception regarding COVID-19 vaccine while their counterparts in the control group who were earlier exposed to fake news on COVID-19 did not significantly change their perception. This study has highlighted the importance of counselling in countering fake news within the context of health promotion. This approach is yet to receive significant attention in literature, especially from developing countries.
