Vaccine confidence volatile, vulnerable to misinformation, global study finds

Political polarisation and online misinformation are threatening vaccination programmes worldwide, with public trust volatile and varying widely between countries, according to a global vaccine confidence study. The study, which maps trends in vaccine confidence across 149 countries between 2015 and 2019, found that scepticism about the safety of vaccines tended to grow alongside political instability and religious extremism. "It is vital with new and emerging disease threats such as the COVID-19 pandemic, that we regularly monitor public attitudes," said Heidi Larson, a professor at the London school of Hygiene & Tropical Medicine who led the research.
