Babies aren't scheduled to be vaccinated against measles until they turn a year old. But this new study in the British Medical Journal finds that infants are vulnerable to the disease from the time they are 2 to 3 months old until they get their shot.
Apparently what's happening is the immunity they inherit from their mother wears off.
Scientists say this finding is an argument for the timeliness of the first dose of the measles vaccine. They also say vaccinations should be considered for infants who are traveling and under the age of 1.
