In a recent study published in the journal Science , researchers investigated the impact of Facebook misinformation and vaccine-skeptical content on coronavirus disease 2019 (COVID-19) vaccination intentions in the United States. Their results indicate that while flagged misinformation reduces vaccination intentions, the far greater exposure to unflagged vaccine-skeptical content from mainstream sources significantly impacted vaccine hesitancy.

Despite extensive research on the spread and psychology of misinformation, its direct causal impact on behaviors such as vaccine uptake remains underexplored. This gap is particularly crucial regarding COVID-19 vaccine misinformation, where correlations have been found between misinformation exposure and lower vaccination rates, but the direction and causality of this relationship are unclear.
Additionally, content that is not factually inaccurate but raises vaccine skepticism could contribute significantly to vaccine hesitancy. Addressing existing knowledge gaps, this study introduced a framework combining experimental data and Facebook exposure data to quantify the causal impact of flagged misinfor.
