Medical experts push back on President Trump's single-disease shots

President Trump wants the measles, mumps, and rubella vaccine to be given in three different single-disease shots. He's also pushing for all childhood immunizations to be given at separate appointments whenever possible. Many medical experts are pushing back, saying the single-shot MMR is safe and effective. Dr. Jodie Guest, senior vice chair of epidemiology at Emory University, talks about it with L.A.'s Morning News.
