If you've already been vaccinated for measles, do you need to get a booster now that it's spreading in the US?

Texas doctors said there's no harm in getting another measles vaccine if you don't know whether you were vaccinated as a child.

After being declared eradicated 25 years ago, measles is making a comeback. The good news is, most people who were vaccinated have good protection. Throughout February, a measles outbreak has been growing in West Texas.
