New York is fighting its worst outbreak ever and Washington state has declared a public health emergency. Unfortunately, misinformation is spreading, and vaccination debates are making headlines.

How can we ensure that our patients and the public are basing vaccination decisions on the best evidence? Do we understand herd immunity and are we educating others about it? And how can we recognize the presentation of measles? Stay informed yourself and share reliable, up-to-date resources:
