“…This finding is consistent with those from other local studies conducted in Italy, where the percentage of women of childbearing age at risk of rubella infection among those tested for rubella antibodies was found to vary from 11.7% to 17.8% among immigrant women [ 17 , 18 ] and estimated at 6.2% among Italian women [ 18 ]. This is also consistent with findings from the most recent studies conducted in other European countries, where rubella susceptibility was found to be 5.9% in Catalonia (Spain) and 6.3% in Liverpool (UK) [ 19 , 32 ], with higher rates observed in immigrant women [ 19 – 21 ].…”

“…Recent immigrants are likely to be less informed about screening opportunities and, when coming from countries where rubella screening is not routinely implemented, they are also likely to have been less exposed to rubella immunization compared with long-term immigrants. Differences by geographical area of origin are in line with findings from Spain [ 19 ], United Kingdom [ 21 ], and the Sicily region of Italy [ 17 ], where decreased RIRs were observed in immigrant women from Africa and Asia. In general, our results are also consistent with findings from other European studies that compared RIR between immigrant children and adolescents and same-age national peers, all showing reduced immunization rates in immigrants [ 13 – 16 ].…”

BackgroundInternational migration rapidly increased in the last decade, raising a renewed attention to its impact on public health. We evaluated differences in rubella immunization rate (RIR) between immigrant and Italian women of childbearing age and tried to identify the driving factors causing them.MethodsWe analyzed data from the Italian behavioral surveillance system PASSI collected in 2011–2015 in a nationally representative sample of residents in Italy. The analysis was performed using log-binomial models to compare RIR between 41,094 Italian women and 3140 regular immigrant women of childbearing age (18–49 years), stratifying the latter by area of origin and length-of-stay in Italy (recent: ≤ 5-years; mid-term: 6-10-years; long-term: > 10-years).ResultsImmigrant women showed a RIR of 36.0% compared to 60.2% among Italian women (RIR-ratio = 0.60, 95% confidence interval (CI): 0.57–0.63). Adjusting for demographic characteristics (i.e., sex, age and area of residence), socio-economic factors (i.e., education, occupation, family composition and economic status) and an indicator of the presence of at least one health-risk behavior (i.e., physical inactivity, current cigarette smoking, excessive alcohol consumption and excess weight) did not significantly change this difference (RIR-ratio = 0.56, 95% CI: 0.53–0.59). Recent immigrants (RIR-ratio = 0.47, 95% CI: 0.42–0.53) and immigrants from high migratory pressure countries (HMPC) in sub-Saharan Africa (RIR-ratio = 0.41, 95% CI: 0.31–0.56) and Asia (RIR-ratio = 0.42, 95% CI: 0.33–0.53) showed the greatest differences in RIR compared with Italian women.ConclusionsDifferences in RIR between immigrant and Italian women were not explained by different demographic, socioeconomic and health-risk behaviors characteristics. As entitlement to free-of-charge immunization in Italy is universal, regardless of migration status, other informal barriers (e.g., cultural and barriers to information access) might explain lower RIRs in immigrant women, especially recent immigrants and those from HMPC in sub-Saharan Africa and Asia. Further investigations are needed to identify obstacles and appropriate promotion and access-enabling strategies for rubella immunization.

Introduction: Rubella infection in pregnancy may cause severe complications, including still birth, miscarriage, preterm labor, growth deficiency, congenital malformation, blindness, cardiac defects, central nervous system abnormalities, and congenital cataract and hearing loss. The purpose of this study was to investigate the seroprevalence of rubella in pregnant women presenting to our hospital for routine antenatal examination, to compare our results with those from other countries, and to contribute to the literature by discussing opinions concerning rubella screening in pregnancy with data from 27.465 patients. Material and Methods: This retrospective study involved anti-rubella IgM and IgG screening results of pregnants in the first trimester, aged 17-45 and presented to our hospital for antenatal examination between 2013 and 2016. Data were collected from the hospital's electronic records system and patient files. Rubella antibody levels were determined using commercially available ELISA kits (ALISEI SEAC, Italy) in the medical microbiology laboratory. Anti-rubella IgM-positive cases were also evaluated using the avidity test. The results were analyzed using the SPSS v.15.0 (SPSS Inc., Chicago, Illinois, USA) data analysis system. Results: Rubella IgM antibody positivity was determined in 205 (0.8%) of 27.465 pregnants whose anti-rubella IgM status was investigated, and positive values were observed in 16.526 (9.2%) of 17.186 cases subjected to anti-rubella IgG antibody analysis. Anti-rubella avidity tests revealed high avidity in 92.7% of patients, low avidity in 3.4%, and intermediate avidity in 3.9%. Conclusion: We think that rubella screening during pregnancy is essential, and that the best means of reducing the adverse effects of rubella virus would be to provide full immunization before pregnancy for females of child-bearing age.

“…16 These strategies have been introduced into regular obstetrics care and have shown good performance in the United Kingdom, Canada, Japan, and other countries. [17][18][19] Therefore, to eliminate rubella infection, the postpartum immunization should be launched and vaccination should be provided to the susceptible women, either native or immigrant, before they are discharged from hospitals. 20 In Taiwan, almost all women have prenatal checkups.…”

Abstract. Vaccination is considered the most effective method to prevent rubella spread and congenital rubella syndrome (CRS). The aim of the present study was to investigate the rubella immunity among native and immigrant pregnant women in Taiwan. From 2000 to 2014, a total of 16,879 pregnant women who received routine prenatal examinations were recruited in this study. The rubella IgG antibodies were assayed using a microparticle enzyme immunoassay or chemiluminescent microparticle immunoassay. Subjects were categorized by nationality and subcategorized by specific periods of time for comparison. The rubella susceptibility was 12.7% in total, 11.1% in Taiwanese and 20.3% in immigrant population from 2000 to 2014. Among the immigrant women, those from Vietnam had the highest susceptibility (22.3%) and those from Thailand had the lowest susceptibility (3.8%). The immigrant women from Vietnam and China showed a significantly higher susceptibility compared with the native Taiwanese women in which the odds ratio was 2.30 (95% confidence interval [CI]: 2.04-2.60), 1.96 (95% CI: 1.59-2.41), respectively ( P < 0.001). It meant that immigrants from Vietnam and China had a higher likelihood of rubella susceptibility and related CRS sequela than native women.
