People heading abroad should be aware of all the appropriate vaccinations they need to ensure safe travel. Research has shown that many Americans don’t get the recommended vaccines that would protect them from certain illnesses.
One study of 40,000 American adult travelers documented that 16 percent of them needed the measles, mumps, rubella (MMR) vaccine but only half of them got it. Although measles was declared eliminated in the United States in 2000, unvaccinated Americans can become infected overseas and can cause outbreaks back home when they return. Measles is highly contagious and is found in developed countries in Europe as well as in less developed areas. And adults who experience measles often have a worse bout of it than children.
