Comment: Serologic study can be useful in establishing that an individual has immunity subsequent to vaccination. In many individuals detectable immunity does not persist. In acute illness, hemagglutinating and neutralizing antibody peak 2 weeks after the rash appears. It is necessary to demonstrate rising titters over 2 weeks after the rash appears. It is necessary to demonstrate rising titers over 2 weeks, or identify IgM antibody to establish diagnosis. Very high serum titers in the absence of acute illness, or high CSF titer, are seen in sub acute sclerosing panencephalitis. Protective antibody levels of antibodies to measles, mumps, and rubella have been assessed by oral fluid sapling. The presence of measles – specific IgG I single serum specimen indicates past or present infection or past vaccination
