The Opportunity Provided by Vaccination Offer to Refugees from Ukraine in European Countries

(1) The Russian invasion of Ukraine forced many people to leave their country and seek asylum in various European countries, with serious consequences from a health perspective. In this context, we describe the health measures undertaken by AcToVax4NAM Consortium Countries (Cyprus-Germany-Greece-Italy-Malta-Poland-Romania-Spain) to prevent Vaccine-Preventable Disease (VPD) outbreaks in the context of mass movements of populations that resulted from the crisis in Ukraine. (2) We collected information on the vaccinations offered to Ukrainians in the Consortium Countries. (3) All these countries have provided Temporary Protection (TP) status to refugees from Ukraine and have followed the recommendations of European and International Agencies to offer them vaccinations according to the National Immunisation Programmes. The COVID-19 vaccination is offered in all countries with regard to the general population. Most countries provide information on TP and access to health/vaccination services in the Ukrainian language. (4) The information collected shows a common effort to ensure the adequate planning of health and vaccination services for refugees from Ukraine and, very often, to include them in the national vaccination offer. It is important that this initial response towards people who have fled Ukraine will be continued following the emergency but, more importantly, that it serves as a best practice towards all migrants and refugees entering the EU.

Exploring COVID-19 Vaccination Willingness in Italy: A Focus on Resident Foreigners and Italians Using Data from PASSI and PASSI d'Argento Surveillance Systems

(1) The COVID-19 pandemic exacerbated health disparities, both between foreign and autochthonous populations. Italy was one of the European countries that was the most affected by the COVID-19 pandemic; however, only limited data are available on vaccine willingness. This study aims to assess the propensity of foreign and autochthonous populations residing in Italy to be vaccinated and the relative associated factors. (2) Data were collected and analysed from the two Italian surveillance systems, PASSI and PASSI d'Argento, in the period of August 2020-December 2021. The data include those of the Italian resident adult population over 18 years old. A multinomial logistic regression model, stratified by citizenship, was used to assess the associations of sociodemographic, health, and COVID-19 experience variables with vaccination attitudes. (3) This study encompassed 19,681 eligible subjects. Considering the willingness to be vaccinated, foreign residents were significantly less certain to get vaccinated (49.4% vs. 60.7% among Italians). Sociodemographic characteristics, economic difficulties, and trust in local health units emerged as factors that were significantly associated with vaccine acceptance. Having received the seasonal flu vaccine was identified as a predictor of COVID-19 vaccine acceptance among foreign and Italian residents. (4) This study underscores the significance of tailoring interventions to address vaccine hesitancy based on the diverse characteristics of foreign and Italian residents. This research offers practical insights for public health strategies, highlighting the importance of tailored educational campaigns, improved communication, and nuanced interventions to enhance vaccine acceptance and uptake within both populations.

Assessing the Adoption of One Health Approaches in National Plans to Combat Health Threats: The Pilot of a One Health Conceptual Framework in Armenia

Due to several factors, such as environmental and climate changes, the risk of health threats originating at the human-animal-environment interface, including vector-borne diseases (VBDs) and zoonoses, is increasing. Low-resource settings struggle to counter these multidimensional risks due to their already-strained health systems and are therefore disproportionally affected by the impact caused by these changes. Systemic approaches like One Health (OH) are sought to strengthen prevention and preparedness strategies by addressing the drivers of potential threats with a multidisciplinary and multisectoral approach, considering the whole system at the human-animal-environment interface. The integration of OH in national plans can be challenging due to the lack of effective coordination and collaboration among different sectors. To support the process of knowledge coproduction about the level of OH integration in prevention and preparedness strategies against health threats in Armenia, a situation analysis was performed on Crimean-Congo hemorrhagic fever/virus and anthrax (identified by local stakeholders as priorities to be addressed with the OH approach), and actions to strengthen the national OH system were identified with the support of a OH conceptual framework. The study highlighted that multidisciplinary and multisectoral efforts towards prevention and preparedness against VBDs and zoonoses threats need to be strengthened in Armenia, and priority actions to integrate the OH approach were identified.

One health adoption within prevention, preparedness and response to health threats: Highlights from a scoping review

Introduction

As the COVID-19 pandemic has demonstrated, the complexity of factors involved in the emergence of health threats requires a holistic One Health (OH) approach to enhance the effectiveness of prevention, preparedness, and response (PPR) strategies. Therefore, we conducted a scoping review to explore how the OH approach has been adopted in the context of PPR strategies to health threats, and the challenges and benefits deriving from its integration.

Methods

We defined the research questions and a strategy to guide the peer-reviewed and grey literature search to identify relevant articles and documents (identification). We assessed them for eligibility according to predefined criteria (screening) and finally included the ones that answered the research questions (inclusion). We performed a descriptive and thematic analysis of the results.

Results

A total of 138 records were included in the review (57 from the peer-reviewed literature and 81 from the grey literature). The OH approach was mainly adopted in prevention strategies, particularly within the governance area. Human and animal health were the most integrated disciplines in the OH approach, while environmental and social sciences were the less integrated. The most targeted threats were antimicrobial resistance and zoonoses, with the African region being the most represented. Conducive factors for the adoption of OH PPR strategies were identified in resolutions and guidance emanating from international organisations.

Discussion

The global governance of OH should utilise conducive factors, such as international resolutions and guidance, to enhance the adoption of multisectoral and multi-actor PPR strategies, that focus on national and international priorities and neglected threats, such as environmental hazards and pandemic risk. Integrated frameworks and metrics for the implementation and evaluation of OH PPR strategies need to be consolidated to contribute to the growing body of evidence supporting the adoption of the OH approach.

Access to Vaccination for Newly Arrived Migrants: Developing a General Conceptual Framework for Understanding How to Improve Vaccination Coverage in European Countries

Objectives: Access to vaccination for newly arrived migrants (NAMs) is a relevant concern that requires urgent attention in EU/EEA countries. This study aimed to develop a General Conceptual Framework (GCF) for understanding how to improve vaccination coverage for NAMs, by characterizing and critically analyzing system barriers and possible strategies to increase vaccination. Methods: A theoretical conceptualization of the GCF was hypothesized based on conceptual hubs in the immunization process. Barriers and solutions were identified through a non-systematic desktop literature review and qualitative research. The GCF guided the activities and facilitated the integration of results, thereby enriching the GCF with content. Results: The study explores the vaccination of NAMs and proposes strategies to overcome barriers in their vaccination process. It introduces a framework called GCF, which consists of five interconnected steps: entitlement, reachability, adherence, achievement, and evaluation of vaccination. The study also presents barriers and solutions identified through literature review and qualitative research, along with strategies to enhance professionals' knowledge, improve reachability, promote adherence, achieve vaccination coverage, and evaluate interventions. The study concludes by recommending strategies such as proximity, provider training, a migrant-sensitive approach, and data collection to improve vaccination outcomes for NAMs. Conclusion: Ensuring equitable access to healthcare services, including vaccination, is crucial not only from a humanitarian perspective but also for the overall public health of these countries.

Risk of Covid-19 Severe Outcomes and Mortality in Migrants and Ethnic Minorities Compared to the General Population in the European WHO Region: a Systematic Review

The Covid-19 pandemic has had a major impact on migrants and ethnic minorities (MEMs). Socio-economic factors and legal, administrative and language barriers are among the reasons for this increased susceptibility. The aim of the study is to investigate the impact of Covid-19 on MEMs compared to the general population in terms of serious outcomes. We conducted a systematic review collecting studies on the impact of Covid-19 on MEMs compared to the general population in the WHO European Region regarding hospitalisation, intensive care unit (ICU) admission and mortality, published between 01/01/2020 and 19/03/2021. Nine researchers were involved in selection, study quality assessment and data extraction. Of the 82 studies included, 15 of the 16 regarding hospitalisation for Covid-19 reported an increased risk for MEMs compared to the white and/or native population and 22 out of the 28 studies focusing on the ICU admission rates found an increased risk for MEMs. Among the 65 studies on mortality, 43 report a higher risk for MEMs. An increased risk of adverse outcomes was reported for MEMs. Social determinants of health are among the main factors involved in the genesis of health inequalities: a disadvantaged socio-economic status, a framework of structural racism and asymmetric access to healthcare are linked to increased susceptibility to the consequences of Covid-19. These findings underline the need for policymakers to consider the socio-economic barriers when designing prevention plans.

Five-hub General Conceptual Framework to improve the vaccination coverage for newly arrived migrants

Background

Within the Project “Increased Access for Newly Arrived Migrants-AcToVax4NAM” (Grant n 101018349, 3rd EU Health Programme), a General Conceptual Framework (GCF) was developed for understanding how to improve vaccination coverage for Newly Arrived Migrants (NAM), by characterizing and critically analysing system barriers and possible solutions to increase vaccination

Methods

A logical pathway was hypothesized based on conceptual hubs in the immunization process. The identification of barriers and solutions was carried on by: a) non-systematic revision of scientific and grey literature, institutions and relevant websites, and documents suggested by Consortium Partners; b) qualitative research conducted in each Consortium Country. The GCF was used as a guide for the above mentioned activities and organize results into the GCF itself to enrich it with content

Results

5 conceptual hubs were identified: ENTITLEMENT to vaccination, REACHABILITY of people to be vaccinated, ADHERENCE to vaccination, ACHIEVEMENT of vaccination, EVALUATION of the intervention. All hubs are linked sequentially, starting with Entitlement without which the process cannot take place. Hubs are connected: if vaccination does not take place, it’s important to go back to the previous hubs to understand the barriers. Reachability-Adherence-Achievement are closely related because some approaches are cross-cutting, such as proximity interventions which, in addition to allowing the system to approach NAM, promote adherence and thus possibility of completing the process. Other strategies may be implemented with different purposes: training aims to foster a culturally competent approach to facilitate adherence and avoid vaccination hesitancy, but also to improve competence in the entire process and lead to vaccination completion

Conclusions

The proposed GCF facilitates identification of barriers and possible solutions to the effective achievement of immunization, at all stages of the process

Key messages

• The GCF can be the basis for the creation of country-specific flow-charts through which to test strategies aimed at increasing immunization coverage in NAM.

• The GCF will be useful at EU level, to facilitate both the harmonisation of approaches and interventions and the evaluation of comparable approaches.

Strengthening preparedness against global health threats: A paradigm shift based on One Health approaches

The implementation of preparedness strategies to prevent and mitigate the impact of global health threats poses several challenges. It should promptly identify cross-cutting drivers of pandemic threats, assess context-specific risks, engage multiple stakeholders, and translate complex data from multiple sources into accessible information for action. This requires a coordinated, multidisciplinary and multisectoral effort engaging systems that, most of the time, work in isolation.

The One Health (OH) approach promotes the collaboration and communication among different disciplines and sectors, and could be applied across the preparedness phases at national and international level.

We discuss here gaps and needs in preparedness strategies, which can benefit from the OH approach, and a set of actionable recommendations, as shared with the G20–2021 with a dedicated Policy Brief.

The discussion adds to the current debate about OH operationalization and promotes a paradigm shift towards coordinated prevention and preparedness strategies for early assessment and management of global health threats.

Risk of SARS-CoV-2 infection in migrants and ethnic minorities compared with the general population in the European WHO region during the first year of the pandemic: a systematic review

BACKGROUND

Migrants and ethnic minorities have suffered a disproportionate impact of the COVID-19 pandemic compared to the general population from different perspectives. Our aim was to assess specifically their risk of infection in the 53 countries belonging to the World Health Organization European Region, during the first year of the pandemic.

METHODS

We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PROSPERO CRD42021247326). We searched multiple databases for peer-reviewed literature, published on Medline, Embase, Scisearch, Biosis and Esbiobase in 2020 and preprints from PubMed up to 29/03/2021. We included cross-sectional, case-control, cohort, intervention, case-series, prevalence or ecological studies, reporting the risk of SARS-CoV-2 infection among migrants, refugees, and ethnic minorities.

RESULTS

Among the 1905 records screened, 25 met our inclusion criteria and were included in the final analysis. We found that migrants and ethnic minorities during the first wave of the pandemic were at increased exposure and risk of infection and were disproportionately represented among COVID-19 cases. However, the impact of COVID-19 on minorities does not seem homogeneous, since some ethnic groups seem to be more at risk than others. Risk factors include high-risk occupations, overcrowded accommodations, geographic distribution, social deprivation, barriers to access to information concerning preventive measures (due to the language barrier or to their marginality), together with biological and genetic susceptibilities.

CONCLUSIONS

Although mixed methods studies will be required to fully understand the complex interplay between the various biological, social, and cultural factors underlying these findings, the impact of structural determinants of health is evident. Our findings corroborate the need to collect migration and ethnicity-disaggregated data and contribute to advocacy for inclusive policies and programmatic actions tailored to reach migrants and ethnic minorities.

Vaccinations for migrants during and beyond the COVID-19 pandemic

Issue

Migrants have suboptimal vaccination coverage compared to the general population in destination countries due to several factors

-administrative barriers or lack of legal entitlements to health -health system barriers (language, lack of cultural sensitivity and community engagement capacity, vaccination costs) -lack of trust in the health system and misconceptions about vaccines due to misinformation or beliefs

Problem

Countries should develop national policies and ensure an inclusive, free of charge and proactive vaccination offer to migrants, irrespective of their legal status; and to extend this approach beyond the current pandemic and the sole COVID-19 vaccine

Results

To achieve COVID-19 global herd immunity all population groups, including migrants, needs to access vaccination. Tailored vaccination strategies, once devised, shall be applied to routine national vaccination plan to tackle health inequalities

Lessons

The following actions shall be implemented at national level

Action 1. Develop tailored and equitable approaches for PH vaccination services targeting migrants through:

-free of charge access -decentralization and outreach capacity of the health system -innovative service delivery models (mobile clinics, combined health services, mass vaccination) -health personnel and migrants participatory approach and engagement strategies

Action 2. Increase staff engagement through: -increasing health personnel's difference sensitivity -strengthening health personnel's communication capacities

Action 3. Increase migrants' health and vaccine literacy through:

-establishing vaccine literacy education programmes and strategies -offering health promotion educational interventions

Action 4. Monitor progress of inclusive vaccination offer by: -setting strategic goals, targets and indicators for national vaccination plans -expanding immunization information systems to monitor vaccination coverage, with appropriate disaggregation by migration status core variables

Key messages

Explicitly and proactively include migrants and displaced communities in vaccination plans and set up, test and implement new approaches in primary prevention and vaccination services. Extend this approach beyond the current pandemic and the sole COVID-19 vaccine in order to enhance preparedness to present and future health threats.

Early childhood vaccination coverage and timeliness by macro-area of origin in children born to foreign women residing in Italy

OBJECTIVES

Country of origin might affect vaccine uptake in children born to immigrants. We aimed to evaluate differences in childhood vaccination coverage (VC) and timeliness by macro-area of origin of foreign mothers residing in Italy.

STUDY DESIGN

Multicentre retrospective birth cohorts.

METHODS

We analysed data of 23,287 children born in 2009-2014 to foreign women in the cities of Rome, Turin and Treviso. We retrieved data through record-linkage of the population, vaccination and birth registries. We estimated VCs at different ages for vaccines against tetanus, measles and meningococcal group-C, using the Kaplan-Meier method. Factors associated with vaccine uptake were evaluated using multilevel Poisson models.

RESULTS

Estimates of VC at any age and for all antigens were significantly lower in children born to women from Asia and higher in children born to women from Africa, as compared to other macro-areas. Similar differences by area of origin were observed for timeliness; independently of mother's sociodemographic characteristics and neonatal outcomes, the probability of delay vaccination after 2 years of age for each antigen was highest in children born to women from Asia. The risk of missed vaccination for all antigens was significantly higher in children born to younger and unemployed women.

CONCLUSIONS

Factors related to area of origin (e.g., cultural habits, language skills) are likely to affect parents' decision to vaccinate their children. These factors, as well as sociodemographic characteristics, should be adequately investigated and addressed to increase vaccine uptake in foreign children, especially those born to Asian women.

What must be done to tackle vaccine hesitancy and barriers to COVID-19 vaccination in migrants?

Migrants have been disproportionately impacted by COVID-19 and emerging evidence suggests they may face barriers to COVID-19 vaccination. Participatory approaches and engagement strategies are urgently needed to strengthen uptake, alongside innovative delivery mechanisms and sharing of best practice, to ensure migrants are better consider within countries’ existing vaccine priority structures.

Epidemiological characteristics of COVID-19 cases in non-Italian nationals notified to the Italian surveillance system

BACKGROUND

International literature suggests that disadvantaged groups are at higher risk of morbidity and mortality from SARS-CoV-2 infection due to poorer living/working conditions and barriers to healthcare access. Yet, to date, there is no evidence of this disproportionate impact on non-national individuals, including economic migrants, short-term travellers and refugees.

METHODS

We analyzed data from the Italian surveillance system of all COVID-19 laboratory-confirmed cases tested positive from the beginning of the outbreak (20th of February) to the 19th of July 2020. We used multilevel negative-binomial regression models to compare the case fatality and the rate of admission to hospital and intensive care unit (ICU) between Italian and non-Italian nationals. The analysis was adjusted for differences in demographic characteristics, pre-existing comorbidities, and period of diagnosis.

RESULTS

We analyzed 213 180 COVID-19 cases, including 15 974 (7.5%) non-Italian nationals. We found that, compared to Italian cases, non-Italian cases were diagnosed at a later date and were more likely to be hospitalized {[adjusted rate ratio (ARR)=1.39, 95% confidence interval (CI): 1.33-1.44]} and admitted to ICU (ARR=1.19, 95% CI: 1.07-1.32), with differences being more pronounced in those coming from countries with lower human development index (HDI). We also observed an increased risk of death in non-Italian cases from low-HDI countries (ARR=1.32, 95% CI: 1.01-1.75).

CONCLUSIONS

A delayed diagnosis in non-Italian cases could explain their worse outcomes compared to Italian cases. Ensuring early access to diagnosis and treatment to non-Italians could facilitate the control of SARS-CoV-2 transmission and improve health outcomes in all people living in Italy, regardless of nationality.

Accessibility to health services in Italy and in the world

Background

The Universal Health Coverage (UHC) proposes that an ideal health system must be able to extend the health coverage to the whole population (universality), to guarantee all the necessary services (globality) and to do it without additional direct costs for the people (free of charge). The achievement of the UHC represents the target 3.8 of the Sustainable Developed Goals. The World Health Organization and the World Bank have developed an index to monitor the UHC (an algorithm that contains 16 indicators of essential health services), while for financial protection they rely on the incidence of catastrophic expenditure on health (percentage of families in which the living expenses for health without reimbursement exceed the10% of consumption).

Objectives

To strengthen the Italian operators' knowledge about the accessibility to health services in Italy and in countries around the world utilizing the UHC index and the incidence of catastrophic expenditure.

Results

The National Center for Global Health of the Italian National Institute of Health (ISS) collected the documents and the data already produced and validated by the international scientific community. ISS in collaboration with the Department of Public Health and Infectious Disease of Sapienza University of Rome developed a workshop training program to bring the UHC concepts at national level in a simplified manner. This was developed in order to encourage a reflection and to strengthen the understanding of the complexity of the UHC. The framework and the program of the workshop will be presented during the conference.

Conclusions

Studying the UHC means focusing on the inequalities in health care. To increase the sensibility of professionals may be a resource to promote the health coverage for all in the national territory.

Key messages

Encouraging the discussion between professionals is possible to understand the complexity of the UHC. The achievement of the UHC may happen only through the improving of the knowledge about it.

Turning constraints into resources: the experience of TRAIN4M&H training program on migrants’ health

Background

The tender TRAIN4M&H (Provision of training for first-line health professionals and law enforcement officers working at local level with migrants and refugees, and training of trainers- contract 20167204), funded by the EC-DG SANTE under the 3rd EU HP, intended to conduct training programme in all EU/EEA countries for health professionals, law enforcement officers an social workers in front-line countries and coach trainers in the others.

Objectives

Training was aimed at reinforcing skills, improving understanding and positive attitudes, and promoting a holistic approach in the work with migrants. The boundaries set by the tender included a short training duration; exclusive use of pre-existing and validated training materials; different professional targets. Italian National Health Institute and Sapienza University of Rome designed the training programme. Criteria for content selection and methodological choices were submitted for consultation to an inter-professional Expert Group in two steps.

Results

Given the limited training timeframe, the delivery of specialised content could not be the focus of this training. It was decided therefore to transform the target requirement into added value, by mixing the target groups into multi-professional classes. This bring a diversity of understandings into the classroom and enhance communication between sectors. The training included also topics such as “context of migration” and “intercultural competences” to create common ground for multi-professional exchange. Similarly, the need to adapt to different EU/EEA contexts argued for a modular structure where Units are selected by the Local Trainer based on a training needs assessment questionnaire sent to trainees beforehand. All materials are on EU Health Policy Platform's Agora (webgate.ec.europa.eu/hpf/).

Conclusions

Training on migrants' health is a complex process, requiring the engagement of learners from their previous experiences and an interdisciplinary approach.

Key messages

Inter-professional training programme can be used for the adult trainings especially in case of a cross-sectoral topic as migrants’ health is. Inter-professional training is a strategy that can guide coherently content design, outcome identification and the choice of evaluations tools.

National immunization policies and practices for migrants in EU/EEA countries

Background

Migrants represent a potential vulnerable group and adequate health protection, including vaccine preventable diseases prevention, should be ensured. The aim of this survey was to map national immunization policies and practices targeting asylum seekers, refugees and irregular migrants in EU/EEA countries.

Methods

A web-based cross-sectional survey was conducted in 28 EU and 2 EEA countries within the ECDC funded Vaccine European New Integrated Collaboration Effort (VENICE) Project in the period January-April 2018.

Results

All countries but one completed the survey and 28 countries offer vaccination to migrants. A national regulation/legal framework supporting migrant immunization is available in most countries. This is specifically established for migrants' health services for 5, part of the National Immunization Programme (NIP) for 15 and both for 3 countries. All the vaccinations included in the NIP appropriate for age are offered to children/adolescents in 27 countries and to adults in 13. In 15 countries offering only certain vaccinations to adults, priority is given to DT, MMR and polio. Vaccinations are mainly given at holding/community level and only 5 countries vaccinate at entry level. A vaccination card is delivered in 23/28 countries to children/adolescents and 24/28 to adults. Recording of individual data vary highly: for children/adolescents and adults, respectively, 15 and 12 countries use an electronic database, 5 and 4 use only paper registry, 2 and 3 use both electronic and paper registries, while 6 and 9 countries do not record information at all. Individual and aggregated data are not made available from the sites where vaccinations are delivered to other local or national institutions in 13 and 15 countries.

Conclusions

Although policies about immunization of migrants are available in most of EU/EEA countries, there are important differences as to their objectives and implementation, especially methods of recording and transmitting data.

Key messages

Given the survey results and the migrants’ mobility, it is important to share data within and across countries to better respond to migrants' immunization needs. Strengthening partnerships between countries of origin, transit and destination, and sharing documentation may ensure the completion of vaccination series and avoid unnecessary revaccinations.

Integrated Early Warning Surveillance: Achilles' Heel of One Health?

Emerging and re-emerging infectious diseases and zoonoses indicate the importance of the One Health (OH) approach for early warning. At present, even when surveillance data are available, they are infrequently timeously shared between the health sectors. In the context of the MediLabSecure (MLS) Project, we investigated the collection of a set of surveillance indicators able to provide data for the implementation of integrated early warning systems in the 22 MLS countries of the Mediterranean, Black Sea and Sahel regions. We used an online questionnaire (covering vector, human, and animal sectors), focusing on seven relevant arboviruses, that was submitted to 110 officially appointed experts. Results showed that West Nile virus was perceived as the most relevant zoonotic pathogen, while Dengue virus was the most relevant non-zoonotic pathogen in the study area. Data collection of early warning indicators is in place at a different level for all the investigated pathogens and in almost all the MLS Countries. Further assessments on the reliability of the collection in place and on the feasibility of piloting an integrated early warning system for arbovirus could verify if integrated early warning really represents the Achilles' heel of OH.

Immunisation of migrants in EU/EEA countries: Policies and practices

In recent years various EU/EEA countries have experienced an influx of migrants from low and middle-income countries. In 2018, the "Vaccine European New Integrated Collaboration Effort (VENICE)" survey group conducted a survey among 30 EU/EEA countries to investigate immunisation policies and practices targeting irregular migrants, refugees and asylum seekers (later called "migrants" in this report). Twenty-nine countries participated in the survey. Twenty-eight countries reported having national policies targeting children/adolescent and adult migrants, however vaccinations offered to adult migrants are limited to specific conditions in seven countries. All the vaccinations included in the National Immunisation Programme (NIP) are offered to children/adolescents in 27/28 countries and to adults in 13/28 countries. In the 15 countries offering only certain vaccinations to adults, priority is given to diphtheria-tetanus, measles-mumps-rubella and polio vaccinations. Information about the vaccines given to child/adolescent migrants is recorded in 22 countries and to adult migrants in 19 countries with a large variation in recording methods found across countries. Individual and aggregated data are reportedly not shared with other centres/institutions in 13 and 15 countries, respectively. Twenty countries reported not collecting data on vaccination uptake among migrants; only three countries have these data at the national level. Procedures to guarantee migrants' access to vaccinations at the community level are available in 13 countries. In conclusion, although diversified, strategies for migrant vaccination are in place in all countries except for one, and the strategies are generally in line with international recommendations. Efforts are needed to strengthen partnerships and implement initiatives across countries of origin, transit and destination to develop and better share documentation in order to guarantee a completion of vaccination series and to avoid unnecessary re-vaccination. Development of migrant-friendly strategies to facilitate migrants' access to vaccination and collection of vaccination uptake data among migrants is needed to meet existing gaps.

Towards harmonisation of entomological surveillance in the Mediterranean area

BACKGROUND

The Mediterranean Basin is historically a hotspot for trade, transport, and migration. As a result, countries surrounding the Mediterranean Sea share common public health threats. Among them are vector-borne diseases, and in particular, mosquito-borne viral diseases are prime candidates as (re)emerging diseases and are likely to spread across the area. Improving preparedness and response capacities to these threats at the regional level is therefore a major issue. The implementation of entomological surveillance is, in particular, of utmost importance. Guidance in designing entomological surveillance systems is critical, and these systems may pursue different specific objectives depending on the disease. The purpose of the proposed review is to draw up guidelines for designing effective and sustainable entomological surveillance systems in order to improve preparedness and response. However, we make it clear that there is no universal surveillance system, so the thinking behind harmonisation is to define evidence-based standards in order to promote best practises, identify the most appropriate surveillance activities, and optimise the use of resources. Such guidance is aimed at policymakers and diverse stakeholders and is intended to be used as a framework for the implementation of entomological surveillance programmes. It will also be useful to collaborate and share information with health professionals involved in other areas of disease surveillance. Medical entomologists and vector control professionals will be able to refer to this report to advocate for tailored entomological surveillance strategies. The main threats targeted in this review are the vectors of dengue virus, chikungunya virus, Zika virus, West Nile virus, and Rift Valley fever virus. The vectors of all these arboviruses are mosquitoes.

METHODS

Current knowledge on vector surveillance in the Mediterranean area is reviewed. The analysis was carried out by a collaboration of the medical entomology experts in the region, all of whom belong to the MediLabSecure network, which is currently funded by the European Union and represents an international effort encompassing 19 countries in the Mediterranean and Black Sea region.

FINDINGS

Robust surveillance systems are required to address the globalisation of emerging arboviruses. The prevention and management of mosquito-borne viral diseases must be addressed in the prism of a One Health strategy that includes entomological surveillance as an integral part of the policy. Entomological surveillance systems should be designed according to the entomological and epidemiological context and must have well-defined objectives in order to effect a tailored and graduated response. We therefore rely on different scenarios according to different entomological and epidemiological contexts and set out detailed objectives of surveillance. The development of multidisciplinary networks involving both academics and public authorities will provide resources to address these health challenges by promoting good practises in surveillance (identification of surveillance aims, design of surveillance systems, data collection, dissemination of surveillance results, evaluation of surveillance activities) and through the sharing of effective knowledge and information. These networks will also contribute to capacity building and stronger collaborations between sectors at both the local and regional levels. Finally, concrete guidance is offered on the vector of the main arbovirus based on the current situation in the area.

Comparison of early childhood vaccination coverage and timeliness between children born to Italian women and those born to foreign women residing in Italy: A multi-centre retrospective cohort study

BACKGROUND

Compared to hosting populations, immigrants are usually considered more vulnerable to communicable diseases, many of which are vaccine-preventable. This study aims to estimate vaccination coverage (VC) and timeliness in children born to women from high migratory pressure countries (HMPC) and to evaluate factors affecting differences with children born to Italian women or women from advanced development countries (ITA + ADC).

METHODS

We retrospectively analysed data of children born in 2009-2014 and resident in areas served by three local health units in the cities of Rome (n = 40,284), Turin (n = 49,600), and Treviso (n = 20,080). Data were retrieved through record-linkage of the population, vaccination, and birth registries. We used the Kaplan-Meier method to estimate VCs at different ages for the 3rd dose of vaccine against tetanus and the 1st dose of vaccines against measles and meningococcal group C. Factors affecting differences in VCs by citizenship were evaluated using log-binomial models.

RESULTS

In Rome, VCs at 2 years of age were consistently higher in children born to ITA + ADC women than in children born to HMPC women, while differences in VCs by citizenship varied according to antigen and birth-cohort in Turin and Treviso, respectively. Where differences were observed, these were only partially explained by the mother's socio-demographic characteristics, level of utilisation of health-services during pregnancy, and maternal, perinatal, and neonatal outcomes. Finally, we observed a reduction of VCs in recent birth cohorts (2012-14 vs. 2009-11), especially in children born to ITA + ADC women.

CONCLUSIONS

Differences in VCs by citizenship were not homogeneous and varied according to geographical context, antigen, and birth-cohort. These differences are likely to be also affected by informal barriers (e.g., linguistic and cultural barriers), which should be addressed in implementing strategies to increase vaccine uptake in foreign children. Moreover, our results suggest that effective strategies to promote vaccinations in the autochthonous population are also needed.

Implementation of the One Health approach to fight arbovirus infections in the Mediterranean and Black Sea Region: Assessing integrated surveillance in Serbia, Tunisia and Georgia

Background

In the Mediterranean and Black Sea Region, arbovirus infections are emerging infectious diseases. Their surveillance can benefit from one health inter‐sectoral collaboration; however, no standardized methodology exists to study One Health surveillance.

Methods

We designed a situation analysis study to document how integration of laboratory/clinical human, animal and entomological surveillance of arboviruses was being implemented in the Region. We applied a framework designed to assess three levels of integration: policy/institutional, data collection/data analysis and dissemination. We tested the use of Business Process Modelling Notation (BPMN) to graphically present evidence of inter‐sectoral integration.

Results

Serbia, Tunisia and Georgia participated in the study. West Nile Virus surveillance was analysed in Serbia and Tunisia, Crimea‐Congo Haemorrhagic Fever surveillance in Georgia. Our framework enabled a standardized analysis of One Health surveillance integration, and BPMN was easily understandable and conducive to detailed discussions among different actors/institutions. In all countries, we observed integration across sectors and levels except in data collection and data analysis. Data collection was interoperable only in Georgia without integrated analysis. In all countries, surveillance was mainly oriented towards outbreak response, triggered by an index human case.

Discussion

The three surveillance systems we observed prove that integrated surveillance can be operationalized with a diverse spectrum of options. However, in all countries, the integrated use of data for early warning and inter‐sectoral priority setting is pioneeristic. We also noted that early warning before human case occurrence is recurrently not operationally prioritized.

[Differences in influenza vaccination coverage among subgroups of adult immigrants residing in Italy at risk for complications (2012-2013)]

OBJECTIVES

to evaluate differences in influenza vaccination coverage (IVC) in immigrants at risk for influenza-related complications, according to their area of origin and length of stay in Italy.

DESIGN

cross-sectional survey conducted on the sample of foreign citizens included in the survey on health conditions and use of health services of the Italian resident population (Italian national institute of statistics, 2012-2013).

SETTING AND PARTICIPANTS

analysis conducted on 885 foreign adult citizens (≥18 years) at risk for influenza-related complications (elderly residents ≥65 years and residents with specific chronic diseases).

MAIN OUTCOME MEASURES

vaccination coverage ratios (VCR) comparison between long-term immigrants (≥10 years) and recent immigrants (<10 years), and between non-African and African immigrants, adjusted by demographic and socioeconomic characteristics and level of health services utilization.

RESULTS

IVC among immigrants was 15.6%, significantly higher in long-term immigrants (18.3%) compared to recent immigrants (10.2%) (VCR: 1.79; 95%CI 1.21-2.66), and in non-African immigrants (17.1%) compared to African immigrants (9.4%) (VCR: 1.82; 95%CI 1.04-3.17). After adjusting on the basis of demographic and socioeconomic characteristics and for level of health services utilization between the compared subgroups, the difference in IVC according to the length of stay was greatly reduced (VCR: 1.41; 95%CI 0.94- 2.10), while IVC difference reduction according to area of origin was less relevant (VCR: 1.66; 95%CI 0.95-2.91).

CONCLUSIONS

demographic and socioeconomic characteristics and level of health services utilization explained part of the difference in IVC between the compared subgroups, particularly between long-term and recent immigrants. The difference in IVC between African immigrants and immigrants from other areas remained quite pronounced even after adjusting on the basis of these factors. This suggests that IVC, especially in African immigrants, is affected by other informal barriers, such as cultural and linguistic barriers, that need to be addressed when planning effective immunization access strategies.
