Area of Science:

• Public Health
• Social Media Analysis
• Behavioral Science

Background:

• Understanding vaccine hesitancy is vital for public health.
• Online behavior significantly influences public health attitudes.
• The COVID-19 pandemic highlighted the need to study vaccine hesitancy and social media.

Purpose of the Study:

• To investigate the association between online behavior and COVID-19 vaccine hesitancy.
• To examine how following specific accounts and engaging with online content relates to vaccine confidence.
• To identify patterns in social media usage among vaccine-hesitant individuals.

Main Methods:

• Two studies combined survey data on COVID-19 vaccine attitudes with Twitter data.
• Analysis included following specific political and news accounts, and interaction with low-quality news sites.
• Network analysis was used to identify online communities and their association with vaccine hesitancy.

Main Results:

• Following US Republican politicians and low-quality news sites correlated with lower COVID-19 vaccine confidence.
• Centrality in right-wing online communities was linked to vaccine hesitancy in the US.
• Retweeting and favoriting low-quality news on Twitter was associated with a higher likelihood of not getting vaccinated.

Conclusions:

• Vaccine hesitancy is associated with engagement with low-quality information and conservative online communities.
• Online behavior, particularly within polarized social media environments, presents challenges for vaccine uptake.
• Targeting misinformation and understanding online social networks are crucial for public health interventions.
