I only received one dose of measles vaccine, am I protected?

One dose of the measles vaccine is about 93% effective. Adults with one dose are generally considered protected but, if concerned, persons who only received one dose of measles vaccine can discuss with their healthcare provider whether a second dose might be desirable, based upon personal and community risk.
