A new study overseen by the Oxford Internet Institute (OII) claims that privacy-preserving browsers such as DuckDuckGo return more health misinformation – such as anti-vaccine sites – than Google. 

The study, published in Frontiers in Medicine, analysed the first 30 webpages returned for the search term “vaccines autism”, to gauge the volume of anti-vax information that came up. It found that “alternative” search engines (Duckduckgo, Ecosia, Qwant, Swisscows, and Mojeek) and other commercial engines (Bing, Yahoo) returned between 10-53 per cent anti-vaccine pages, while Google returned 0 per cent.
