As Clark County, Washington, combats an ongoing measles outbreak, Facebook announced Thursday that it’s diminishing the reach of anti-vaccine information on its platform. It will no longer allow it to be promoted through ads or recommendations, and will make it less prominent in search results. The social network will not take down anti-vaccine posts entirely, however. The company also said it was exploring ways to give users more context about vaccines from “expert organizations.”

The decision was widely anticipated: Facebook, along with YouTube and Amazon, has faced criticism from journalists and lawmakers in recent weeks for allowing vaccine misinformation to flourish on their sites. Facebook also told media outlets in February that it was looking into how it should address anti-vaccination content.
