(CNN) Facebook will soon take action against misinformation about vaccines, according to a Facebook representative.

Public health experts have pointed fingers at social media platforms, saying that false claims that vaccines cause autism and other diseases have frightened parents into refusing to vaccinate, resulting in the current measles outbreak that started in Washington state.

The Facebook representative, who asked not to be named, said the social media giant is working with health experts to decide what changes to make and considering a combination of approaches to handle vaccine misinformation. These approaches wouldn't take misinformation off Facebook but rather make it less prominent.

For example, groups that promote vaccine misinformation wouldn't show up in the list of groups that Facebook recommends users join. Also, Facebook would make sure that posts containing vaccine misinformation would appear farther down in a user's newsfeed.

Public health and technology experts welcomed the planned changes. "This is good news," said Art Caplan, head of the Division of Medical Ethics at the New York University School of Medicine. "They're incremental steps, but they're heading in the right direction."
