Anti-science extremism in America: escalating and globalizing

The last five years has seen a sharp rise in anti-science rhetoric in the United States, especially from the political far right, mostly focused on vaccines and, of late, anti-COVID-19 prevention approaches. Vaccine coverage has declined in more than 100 US counties leading to measles outbreaks in 2019, while in 2020 the US became the epicenter of the COVID-19 pandemic. Now the anti-science movement in America has begun to globalize, with new and unexpected associations with extremist groups and the potential for tragic consequences in terms of global public health. A new anti-science triumvirate has emerged, comprised of far right groups in the US and Germany, and amplified by Russian media.
