Vaccine-preventable disease outbreaks are occurring more often in the United States, but so is state legislation tailored to increase childhood vaccination levels, according to a 7-year analysis published yesterday in JAMA Pediatrics.

The new findings come following a surge of measles activity in the United States this year, mostly fueled by a few large outbreaks that nearly cost the nation the measles elimination status that it achieved in 2000.
