    Introduction. Although the benefits of vaccinations have been extensively demonstrated, vaccination coverage remains unsatisfactory as result of many people's poor knowledge and negative perception of vaccination. We evaluated the impact of an education course on vaccinations in a population of pregnant women. Methods. A total of 214 pregnant women were invited to participate in this project, which was undertaken at the Obstetrics and Gynaecology Department of Careggi University Hospital in Florence (Italy). Anonymous questionnaires were administered to women before and after the intervention. A descriptive and statistical analysis was carried out in order to compare the responses obtained before and after the intervention. Results. Adherence to the initiative was good (98%): Initially, the respondents were not hostile to vaccinations, though many (43%) were poorly or insufficiently informed. The educational intervention had a positive impact. After the intervention, the number of women who rated their level of knowledge of vaccinations as poor or insufficient had decreased by 30% and the number of "hesitant" respondents had decreased with respect to all aspects of the study, especially the decision to be vaccinated during pregnancy. Conclusions. Hesitancy stems from a lack of accurate information. Healthcare professionals need to improve their communication skills. Appropriate education during pregnancy, when women are more receptive, may have a highly positive impact. These observations need to be considered in the planning of courses to prepare pregnant women for delivery also in other maternal-foetal centres in Italy

    Background. In Italy one third of bacterial meningitis are caused by Neisseria meningitidis. In March 2005, the Regional Health Authority of Tuscany included the meningococcal serogroup C conjugate (MCC) vaccine in the recommended vaccination pro- gram with a schedule of three doses to all newborns at 3, 5 and 13 months of age (from 2008 amended to a single dose at 13 months) and a single catch-up dose until age 6. Objective. To evaluate the impact of the current national and regional immunization strategies against N. meningitidis and to highlight new perspectives for meningococcal disease prevention with the existing tetravalent meningococcal vaccine (ACWY) and with the future incoming meningococcal B vaccines. Methods. Meningitis incidence rates in Italy and in Tuscany were calculated for the period 1994-2011 and 2005-2011,respectively. Immunization coverage with MCC vaccine in Tuscany and vacci- nation status of meningitis cases were reported. Literature review on meningococcal conjugate vaccine use and recommendation was performed. Results. A decrease in incidence rates of meningococcal menin- gitis was observed in all age groups involved in the immunization campaign. Immunization coverage with MCC increased progres- sively year by year in Tuscany. A herd immunity effect was meas- ured in unvaccinated age groups. Since 2006 no cases of invasive meningococcal C infection in vaccinated subjects were observed in Tuscany. Conclusions. Implementation of MCC vaccination in Tuscany was effective in preventing meningococcal C disease, confirming the effectiveness of the vaccine. A new tetravalent (ACWY) con- jugate vaccine is now available and its use in all Italian Regions should be considered. The full article is free available on www.jpmh.or

    Estimating the scale of chronic hepatitis B virus infection among migrants in EU/EEA countries

    Background: Chronic hepatitis B (CHB) related morbidity and mortality can be reduced through risk group screening, linkage to care and anti-viral treatment. This study estimates the number of CHB cases among foreign-born (migrants) in the European Union and European Economic Area (EU/EEA) countries in order to identify the most affected migrant populations. Methods: The CHB burden was estimated by combining: demographic data on migrant population size by country of birth in the EU/EEA, extracted from European statistical databases; and CHB prevalence in migrants' countries of birth and in EU/EEA countries, derived from a systematic literature search. The relative contribution of migrants from endemic countries to the total CHB burden in each country was also estimated. The reliability of using country of birth prevalence as a proxy for prevalence among migrants was assessed by comparing it to the prevalence found in studies among migrants in Europe. Results: An estimated 1-1.9 million CHB-infected migrants from endemic countries (prevalence ≥2%) reside in the EU/EEA. Migrants from endemic countries comprise 10.3% of the total EU/EEA population but account for 25% (15%-35%) of all CHB cases. Migrants born in China and Romania contribute the largest number of infections, with over 100,000 estimated CHB cases each, followed by migrants from Turkey, Albania and Russia, in descending order, with over 50,000 estimated CHB cases each. The CHB prevalence reported in studies among migrants in EU/EEA countries was lower than the country of birth prevalence in 9 of 14 studies. Conclusions: Migrants from endemic countries are disproportionately affected by CHB; their contribution however varies between EU/EEA countries. Migrant focused screening strategies would be most effective in countries with a high relative contribution of migrants and a low general population prevalence. In countries with a higher general population prevalence and a lower relative contribution of migrants, screening specific birth cohorts may be a more effective use of scarce resources. Quantifying the number of CHB infections among 50 different migrant groups residing in each of the 31 EU/EEA host countries helps to identify the most affected migrant communities who would benefit from targeted screening and linkage to care

    Sexual behavior, use of contraceptive methods and risk factors for HPV infections of students living in Central Italy: implications for vaccination strategies

    Get PDF
    The most frequent risk factors related to the infection/persistence of HPV in the population are an early start of sexual activity, the number of sexual partners, smoking, and the utilization of some contraceptive methods. In Italy, HPV vaccine is offered free of charge to all 12 year-old female adolescents, with a possible extension to other age groups according to Regional policies. In order to value the suitability of the current HPV vaccination strategies in Italy, an epidemiological study on sexual habits in adolescents and young adults was organized. An anonymous questionnaire on sexual behavior and risk factors for HPV infection was administered to 2300 students aged 13-24 years attending secondary schools and universities in Tuscany during 2008-09. About 12% of the sample declared to be foreign citizen. The results highlight the early start of sexual activity among young students. Particularly, more than half of the interviewed students declared to be already sexually active. The mean and the median age of the first sexual intercourse was 15.4 ± 1.4 years and 15 years (25th and 75th percentiles = 14-16), respectively. More than 77% of students at age 16 years declared they already had the first sexual intercourse, compared with 0.3% of those inf. 12 years. Generally, females aged 13-16-years, if sexually active, had sexual contacts with a single partner. Most students declared to know common contraceptive methods (male condom and contraceptive pill). However, only half of them declared a regular use of male condom. These data confirm the importance of vaccination against HPV for young females before their sexual debut. In addition, the current multi-cohort strategy of HPV vaccination in Tuscany (free of charge in the age range 12-16 years) allows also to catch up those girls that have not yet had their first sexual experiences before 16 years (21.5% according to our study) but also to those girls already sexually active, who very rarely are already infected by all vaccine types at 16 years. Our results also show the importance of sexual health education and of promotion of correct behaviours in schools
