A seroepidemiological study of measles: Some practical implications for measles immunization program, Kingdom of Saudi Arabia.

It was hypothesized that the recent outbreaks of measles in a geographically defined area of Al-Qassim might reflect significant changes in the epidemiology of measles and cast doubt upon the real protective value of measles vaccines. Therefore, the two objectives of this research were to study some epidemiological parameters of cases of measles (n=993) and the current immunological status of immunized children (n=2810). The crossmatched data about measles patients were collected on an official proforma and 3 mL of blood were extracted from each child for determining the measles IgG and IgM antibodies.
