Limitations:

Measles (rubeola) is caused by a paramyxovirus, and despite vaccination programs has had several recent local epidemics. Revaccination appears to be of greater value at 11-12 years of age than at 4-6 years of age. Serologic study can be useful in establishing that an individual has effective immunity subsequent to vaccination. In many individuals, detectable immunity does not persist.

Methodology:

Enzyme Immunoassay (EIA)
