Could I still get measles if I am fully vaccinated?

Very few people-about three out of 100-who get two doses of the measles vaccine will still get measles if exposed to the virus. Experts aren't sure why. It could be that their immune systems didn't respond as well as they should have to the vaccine. But the good news is persons who received 2 doses of the measles vaccine (fully vaccinated) and who still get measles typically have a milder illness. Fully vaccinated people are less likely to spread the disease to other people, including people who can't get vaccinated because they are too young or have weakened immune systems.
