CBS News (10/10, Welch) reported that new research presented this week at an infectious disease conference in San Diego suggests that “of the nearly 41,000 international U.S. fliers examined, 16 percent needed the measles, mumps and rubella (MMR) vaccine – but only about half of them actually got it.” Health experts note this is dangerous “because most measles outbreaks in the US are caused by unvaccinated people who are infected overseas.” In a statement, lead study author Dr. Emily Hyle, an infectious disease specialist and instructor at Harvard Medical School and Massachusetts General Hospital, said, “Measles is one of the most contagious diseases in the world and even brief exposure can lead to infection.”
