Texas No. 1 'hotspot' for vaccine exemptions

Four Texas cities, including Houston, rank among the 15 metropolitan "hotspots" of vaccine exemptions, more than any other state, according to a new study. The study found Austin, Fort Worth and Plano also are among the nation's cities with the highest rate of kindergartners not getting vaccinated for non-medical reasons. Since 2009, the proportion of children opting out of such recommended vaccines increased in Texas and 11 other states, the study showed.
