Julia Mason , MD , is a practicing pediatrician and children’s health advocate.

She says the idea that the MMR vaccine may be even more dangerous than measles is being discussed by Health and Human Services secretary.

Mason: Measles is the most contagious virus in humans; it can float in the air and survive on surfaces after a child with measles is in a room.
