many rashes look similar to measles but a vaccinated child at age 12 months should not be contracting measles unless there was a confirmed direct exposure. measles is uncommon in the u. s. now but i do not know where you live. have her examined by her medical provider and read a bit more about the signs and symptoms of measles on webmd. a rash is not the only sign.
can young children (age 2) get measles after having 1 mmr vaccine at 12 months of age? . my daughter (age 2) has a rash and fever. the rash looks very similar to measles.
