Measles is a serious respiratory infection caused by a virus.

Symptoms include:

  • High fever
  • Aches and pains
  • Runny nose
  • Coughing
  • Red eyes
  • Rashes

Complications include:

  • Ear infection
  • Deafness
  • Pneumonia
  • Immune system having to re-learn how to deal with bacteria and viruses. The patient might get sick often in the next few years
  • 1 in 1000 patients have swelling of the brain, often resulting in permanent brain damage
  • 3 in 1000 patients have complications in the respiratory and nervous systems
  • Degenerative disease of the nervous system about 7 to 10 years down the road
  • Death

Measles spreads very easily through coughing and sneezing.

  • 9 out of 10 people who come into contact with measles will be infected
  • The measles virus can stay in the air for 2 hours

Measles is preventable through vaccination (MMR or MMRV)

  • Two doses of MMR vaccine are about 97% effective at preventing measles
  • One dose of MMR vaccine is about 93% effective
  • MMR and MMRV vaccines are safe and effective
  • Vaccination schedule

For individuals who are immune compromised:

  • There have been four studies of the safety of the MMR vaccine in people with 22q11.2DS which showed that most people can get the vaccine safely
  • Consult with an immunologist if you are not vaccinated yet
