Among 854 infants, residual maternal antibodies against measles virus were detected in
35% at the age of 4–5 months, in 16% at 6–7 months and in less than 10% at 8 months or …

Measles virus specific antibody levels were measured in infants from 2 to 12 months of age.

when most mothers had natural measles. Nowadays many mothers have received measles …

• The hemagglutination inhibition (HI) serologic responses of 851 measlessusceptible
infants and children to the live, further-attenuated measles virus vaccine were evaluated …

Three possible reasons for failure of measles vaccine were identified as follows:(a)
circulating maternal antibodies,(b) administration of non-viable vaccine, and (c) …

The natural decline of passively acquired maternal antibody titers and the influence of these
antibodies on the efficacy of live, further attenuated measles vaccine were studied in 7 to 12 …

A serologic study was made in 34 children immunized against measles at the age of 12
months. Using a sensitive virus neutralization test, it was found that many of the children had …

Maternal immunity to measles was studied in a group of 500 newborn children and another
group of 500 children aged one to 12 months, before vaccination. The geometric mean titer …

The present investigation was done to determine whether measles enzyme immune assay
(EIA) absorbency values were lower in women born in the vaccine era after 1963 and their …

Neutralizing antibody titers of 47 infants whose mothers sustained measles (measles group)
and 70 whose mothers were vaccinated (vaccine group) were compared at birth, 4 and 8 …
