Serological statuses of pregnant women in an urban Brazilian population before and after the 2008 rubella immunization campaign

Vaccinating populations against rubella aims to mitigate viral circulation and to ensure that women of childbearing age are immunized to reduce the incidence of congenital rubella syndrome. This study determined the serological statuses of pregnant women in an urban Brazilian population before and after the national rubella immunization campaign that was undertaken in 2008, and it assessed the socio-demographic factors associated with seronegativity.
