AI-based study of social media maps SARS-CoV-2 vaccine hesitancy across the US
The unprecedented speed with which a new class of mRNA severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine has been developed, trialed, approved and rolled out has left many in awe. But it has also left many unnerved.
Resistance to SARS-CoV-2 vaccines over concerns about their efficacy and safety has been reported all over the world but is thought to be particularly pronounced in the United States, where the anti-vaccine lobby has historically been large.
In May 71% of US adults indicated that they would definitely or probably obtain a vaccine to prevent COVID-19 if it were available. The percentage dropped sharply, however, to 51% in September. The survey shows that the US public is concerned about the safety and effectiveness of possible vaccines, and the pace of the approval process.”
