Frequently Asked Questions  
Question: What are the symptoms of measles? 
Answer: Measles begins with a fever that lasts for a couple of days, followed by a cough, a runny nose, conjunctivitis (pink eye), and a rash. The rash typically appears first on the face, along the hairline, and behind the ears and then affects the rest of the body. After about 5 days, the rash fades in the same order in which it appeared.
Q: Given the community outbreak (currently in Baltimore, Maryland), how can I prevent getting measles? 
A: The best way to prevent measles and its spread is to get vaccinated. The measles vaccine is very effective, resulting in lifelong immunity for 97% of people who receive 2 doses. One dose of MMR vaccine is about 93% effective against measles.* The measles vaccine is part of the MMR (measles, mumps, and rubella) vaccine, which helps prevent all 3 viral infections. In addition, practicing good hand hygiene and respiratory etiquette (covering cough/using a tissue) is advised. 
Q: How do I know if I should have the measles vaccination? 

A: All persons less than 19 years of age should complete a primary measles immunization series with 2 doses of MMR vaccine. You do not need the MMR vaccine if you are: 

  • (Child who has) Already had 2 doses of the MMR vaccine 
  • (Adult who has) Already had 1 dose of the MMR vaccine and are not at high risk of measles exposure 
  • Someone born before 1957 and not in a group at higher risk for measles exposure 


  • Had blood tests that show you are immune to MMR (measles, mumps, and rubella.
Q: Is it the same as German measles? 
A: No, the strain that’s in the community is measles, not German measles.
Q: How long after being vaccinated will it take for me to be immune? 
A: The vaccine takes about 2 weeks to provide protection against measles.
Q: What should I do if I have symptoms or think I’ve been exposed?

Q: I have a child less than 6 months of age and am concerned about their being exposed to measles. Can I get them vaccinated early? 
A: The MMR vaccine is not approved for children less than 6 months of age. Children in this age group typically have measles antibody, acquired from their mother before birth, which provides protection from the disease. 
Q: Besides vaccination, what else can I do to avoid infection? 
A: While hand hygiene will not prevent measles, it is the number one way to prevent the spread of infections. Practice proper hand hygiene and respiratory etiquette such as covering cough/using a tissue.
Q: I am pregnant — what should I do to protect myself and my baby from measles? 
A: Measles infection during pregnancy can be associated with increased complications to both the mother and baby. Prior immunizations help protect both the mother and baby during pregnancy.
