The Pfizer-BioNTech vaccine is a top target of conspiracy theories

The Pfizer-BioNTech coronavirus vaccine became a target of conspiracy theories and disinformation campaigns as soon as it was announced, reaching millions of people on sites like Twitter, Reddit and 4chan, according to a recent analysis from a cyber defense firm.

COVID-19 conspiracy narratives, like the false belief that the vaccine was delayed for political reasons, flourished on social networks in the fall and early winter, according to the New York tech security firm Blackbird. The firm created an algorithm to analyze posts in real-time by hunting for signals of what CEO Wasim Khaled calls "synthetic amplification," which indicate activity by botnets and anti-vaccination influencers.  These bogus notions about the vaccines, amplified by a relatively small number of fake accounts and real influencers, reached millions of people, Khaled said.
