The White House turned up the pressure on Silicon Valley to get a handle on vaccine misinformation Thursday, specifically singling out 12 people one group dubbed the “disinformation dozen,” saying they were responsible for a great deal of misinformation about Covid-19.

“There’s about 12 people who are producing 65% of anti-vaccine misinformation on social media platforms,” White House Press Secretary Jen Psaki said Thursday.
