Facebook has rolled out a new feature to try and combat the spread of vaccine misinformation online.
Starting this week, when Facebook and Instagram users search "vaccine" on either site they'll see a prompt to connect them to official information from the Centers for Disease Control or the World Health Organization.
"When it comes to health, everyone wants reliable, up-to-date information. The World Health Organization (WHO) has information that can help answer questions you may have about vaccines," reads a mock-up of the message from Facebook.
The social media giant announced earlier this year it would be removing groups and pages that spread misinformation about vaccinations.
Federal health officials have attributed a recent spike in the number of measles cases in part to misinformation that has made some parents shun the vaccine.
