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

A hospital in Texas on Wednesday confirmed the death of an unvaccinated child who was infected with measles—the first fatality in a two-state measles outbreak that began in January, according to the Associated Press.

Vaccination provides long-lasting 97% protection against measles infection. Most people who have been vaccinated do not need to be vaccinated again.
