For Those Traveling to or from Current Measles Outbreak Areas

The measles vaccination is known to be 95% effective in creating lifelong immunity in recipients. A second dose is recommended to provide immunity to the 5% who do not develop it with the first dose.

The U.S. Centers for Disease Control and Prevention, a founding partner of the Measles & Rubella Initiative, has a number of helpful resources for those traveling both to and from regions experiencing  measles outbreaks areas, and information on immunity conferred post-measles vaccination. Speaking with your primary care doctor immediately is always a good idea if you have any concerns or have been possibly exposed to the measles virus.
