US measles cases double; parents accelerate MMR second dose

Measles cases in the US have doubled year-over-year, prompting parents to seek the second MMR dose earlier than the standard schedule, aligning with guidance in Germany, the UK, and France. The CDC permits the second dose as early as four weeks after the first, but the shift reflects growing public concern amid an accelerating outbreak. The development signals a potential change in vaccination behavior that could affect outbreak control, though the full impact on case trajectory remains uncertain.
