Measles immunity passed from mother to baby may erode quicker than believed, study says

Masles antibodies passed by pregnant women to their babies in the womb, protecting infants early in life, actually disappear quicker than had been previously recognized, leaving babies vulnerable to the sometimes fatal infection for much of their first year of life, according to a new study.

The authors say their findings underscore the importance of widespread immunization against measles, which produces a phenomenon known as “herd immunity” — whereby measles viruses brought into the country by sick travelers can’t get to the vulnerable because so many people are protected. In the case of measles, that’s particularly important for infants; in babies, the risk of complications from the illness and of death is higher than in older children.
