    This paper investigates the factors that contributed to the proliferation of online COVID skepticism on Twitter across Italian municipalities. We demonstrate that socio-demographic factors are likely to mitigate the emergence of skepticism, while populist political leanings were more likely to foster it. Furthermore, we find that the presence of pre-COVID anti-vax sentiment, represented by old "truthers" on Twitter, amplifies online COVID skepticism in local communities. Additionally, exploiting the spatial variation in economic restrictive policies with severe implications for suspended workers belonging to non-essential economic sectors, we find that COVID skepticism spreads more in municipalities significantly affected by this economic lockdown. Finally, the diffusion of COVID skepticism is positively associated with COVID vaccine hesitancy.

    This paper quantifies the impact of online vaccine skepticism on pediatric vaccine uptake, vaccine-preventable hospitalizations, and their related costs. We propose an instrumental variable strategy that leverages the complex structure of social networks. By matching Italian vaccine-related tweets for 2013-2018 with vaccine coverage and preventable hospitalizations data, we find that a 10pp increase in anti-vaccine sentiment causes a 0.43pp decrease in Measles-Mumps-Rubella vaccine coverage. This shift results in an additional 2.1 hospitalizations per 100,000 residents and an 11% increase in relevant healthcare expenses. Conversely, we find no statistically significant impact on vaccines not targeted by online misinformation (e.g., Hexavalent, Meningococcal, Pneumococcal). The results of a simulated model further suggest that informative campaigns are the most effective method to mitigate the effects of online misinformation and reduce polarization.

    This paper quantifies the impact of online vaccine skepticism on pediatric vaccine uptake and health outcomes. We propose a novel methodology that combines Natural Language Processing and an instrumental variable strategy that leverages the intransitivity of the social network's connections. By matching the universe of Italian vaccine-related tweets for 2013-2018 with vaccine coverage and preventable hospitalizations at the municipality level, we find that a 10pp increase in anti-vaccine sentiment causes i) a 0.43pp decrease in coverage of the Measles-Mumps-Rubella vaccine, ii) additional 2.1 hospitalizations among vulnerable populations per 100,000 residents, and iii) an 11% increase in the relevant healthcare expenses, equivalent to 7,311 euros. Drawing on the results of a simulated model, we further show the importance of targeted interventions to counter misinformation and improve vaccine uptake.
