Measles cases reported — check your MMR vaccination

  • Verify that you and your children have received 2 doses of MMR vaccine
  • If you're not vaccinated, talk to your doctor about getting vaccinated now
  • Watch for symptoms: high fever, cough, runny nose, red eyes, followed by a rash 3-5 days later
  • If exposed, contact your doctor — post-exposure vaccination within 72 hours may prevent illness
