optimal age for vaccination against measles in the state of são paulo, brazil, taking into account the mother's order to investigate if the changing levels of measles antibody in women resulting from extensive vaccination programs influence the susceptibility of children, we measured the seroprevalence of measles virus antibody of children in the first year of life and of their mothers. we compared maternal antibody decay of two groups of children: those whose mothers were 25 years old or more (mothers born in the pre-vaccination era), and less than 25 years old (mothers born in the vaccination era). t ...200111567768
identification of primary and secondary measles vaccine failures by measurement of immunoglobulin g avidity in measles cases during the 1997 são paulo epidemic.despite almost universal use of measles vaccines in recent decades, epidemics of the disease continue to occur. understanding the role of primary vaccine failure (failure to seroconvert after vaccination) and secondary vaccine failures (waning immunity after seroconversion) in measles epidemics is important for the evaluation of measles control programs in developing countries. after a measles epidemic in são paulo, brazil, 159 cases previously confirmed by detection of specific immunoglobulin m ...200414715557
