Facebook steps up vaccine misinfo efforts. Will it work?

Facebook says it’s going all in to block the spread of bogus vaccine claims. In practice, that means the social network plans to ban a new bunch of false claims in addition to the old bunch of false claims about vaccines or COVID-19. Among Facebook’s new targets: claims include that vaccines aren’t effective or that they’re toxic, dangerous or cause autism, all of which have been thoroughly debunked. The platform had already prohibited users from spreading falsehoods such as: masks are ineffective; vaccines cause infertility; vaccines contain tracking microchips; and vaccines don’t actually exist.
