Facebook froze as anti-vaccine comments swarmed users

When a Facebook researcher suggested disabling comments on vaccine posts in March until the platform could do a better job of tackling anti-vaccine messages lurking in them, that proposal was ignored.

By altering how posts about vaccines are ranked in people's newsfeeds, researchers at the company realized they could curtail the misleading information individuals saw about COVID-19 vaccines and offer users posts from legitimate sources like the World Health Organization.

"Given these results, I'm assuming we're hoping to launch ASAP," one Facebook employee wrote, responding to the internal memo about the study.

Instead, Facebook shelved some suggestions from the study. Other changes weren't made until April.
