Passive immunity against measles decreases during the first months of life. The objective of
this study was to determine titres of measles antibodies in children aged 9–14 months and …

The majority of infants will not be protected by maternal antibodies until their first measles
vaccination between 12-15 months of age. This provides incentive to reduce the age of …

BACKGROUND: Previous studies have suggested that girls may have lower maternal
measles antibody levels than boys. Girls might therefore be more likely to contract measles …

Background The majority of infants will not be protected by maternal antibodies until their
first measles vaccination, between 12 and 15 months of age. This provides incentive to …

Background. Maternally derived passive measles antibody may interfere with vaccine-
induced immunity in infants less than 12 months of age. However, early loss of passive …

A two-dose vaccination programme, using a combined measles, mumps and rubella vaccine
(MMR) and administration at the ages of 18 months and 12 years, was introduced into …

Background. Given the high infant measles mortality rate, there is interest in whether a
measles immunization regimen beginning at< 12 months of age provides lasting immunity …

Objective To evaluate the persistence of measles antibodies after 2 doses of measles
vaccine in a setting where exposure to wild-type measles was unlikely. Measles was …

Hypothesis. The low titer of measles antibody in infants of mothers with vaccine-induced
immunity may allow immunization against measles before 15 months of age. Methods. Six …

To evaluate the recent decision of the Advisory Committee on Immunization Practice to
increase the recommended age for initial measles vaccination from 12 to 15 months, we …
