[Sero-epidemiological studies of the anti-rubella immunological status of a sample of the female population].

A retrospective study on the prevalence and distribution of haemoagglutination inhibiting rubella antibodies in a sample of 4493 women (3150 in pregnancy), showed a low percentage of vaccinated women ( 0.6%) and high share of negative sera (12.6%). The Authors carried on the analysis subdividing the data according to age of the women, their pregnancy's condition or quarter, their residence (Rome and out of Rome) and occupation (housewife and not). The Pearsonian chi-square showed a significant difference between the lower immunization of housewife group and that of non-housewife group. Moreover the seropositivity decreases according to aging.
