Measles hemagglutinin-inhibiting and neutralizing antibody titers are lower in women young
enough to have been immunized by vaccination than in older women. In the children of both …

Determinants of measles vaccine-induced immune response in infancy include maternal
immune status and the infant's age at immunization. In a previously published study, 74% of …

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 …

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 …

Maternal, cord and infant measles antibody levels were measured and compared in a group
of 411 vaccinated mothers and 240 unvaccinated mothers, and their babies, between 1983 …

During outbreaks of measles, measles vaccine is recommended for infants considered to be
at risk who are 6 months of age and older. In a prospective trial the serologic response to …

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 …

As a result of a large community outbreak of measles, measles hemagglutination inhibition
(HI) titers were measured in 465 immunized children. Titers of less than 1: 4 were found in …

• During a measles outbreak, 660 hospital employees of widely varying ages were screened
for immunity to the disease using an automated indirect fluorescent antibody technique. Of …

Context.—Measles causes serious morbidity in infants, with the highest risk among those
who are 6 to 12 months of age. In the United States, measles vaccine has been given at age …
