Alarm as CDC calls for separate MMR vaccines despite measles outbreak

Concerns that three separate shots would be more costly and time-consuming, and keep kids from being vaccinated

Jim O'Neill, the deputy secretary of the US Department of Health and Human Services (HHS) and the acting director of the US Centers for Disease Control and Prevention (CDC), called on Monday for new vaccines to replace the current MMR shots.
