Vaccines are a documented success story, one of the most successful public health interventions in history. Yet there is a vocal anti-vaccination movement, featuring celebrities (including actress Jenny McCarthy and British rapper M.I.A., who attracted attention for tweeting during the pandemic "If I have to choose the vaccine or chip I'm gonna choose death") and the propagation of anti-vax claims through books, documentaries, and social media. In Anti-vaxxers, Jonathan Berman explores the phenomenon of the anti-vaccination movement, recounting its history from its nineteenth-century antecedents to today's activism, examining its claims, and suggesting a strategy for countering them.
