The measles vaccine is safe and effective, pediatrician Ken Haller said; there’s no reason not to get it.
“This virus is very tenacious,” Haller told “St. Louis on the Air” host Don Marsh on Tuesday. “If someone with measles walks into a room and even just breathes, it can stay in the air for two hours. Anyone coming into that room who’s susceptible has a 90 percent chance of getting sick from it.”
