RESUMEN
BACKGROUND: Herpes Zoster is an age dependent disease and as such it represents a problem in the Italian social context, where the demographic curve is characterized by an overrepresentation of the elderly population. Vaccines against Herpes Zoster are available, safe and effective, however coverage remains sub-optimal. This study was therefore conducted to examine the variations in Herpes Zoster vaccine uptake and confidence across different regions in Italy. METHODS: This study utilized a cross-sectional computer-assisted web interview (CAWI) methodology. The survey was conducted by Dynata, an online panel provider, and involved 10,000 respondents recruited in Italy between April 11 and May 29, 2022. The sample was stratified based on geographic region, gender, and age group. Data management adhered to European Union data protection regulations, and the survey covered demographics, living conditions, and vaccination against herpes zoster (HZ), following the BeSD framework. RESULTS: The findings indicate regional disparities in herpes zoster vaccine uptake across Italy. Notably, the Islands region exhibits a particularly low vaccination rate (2.9%), highlighting the need for targeted interventions. The multivariate regression analysis showed that sociodemographic factors, limited access to healthcare services, and inadequate awareness of vaccine eligibility contribute to the lower uptake observed in this region. CONCLUSION: In conclusion, this research emphasizes regional disparities in herpes zoster (HZ) vaccination uptake in Italy. Demographic, socioeconomic, and geographic factors impact individuals' willingness to receive the vaccine. The study highlights the importance of awareness of vaccine eligibility and accessible vaccination facilities in increasing uptake rates.

BACKGROUND: Streptococcus pneumoniae infections, including Invasive Pneumococcal Diseases (IPDs), pose a substantial public health challenge, causing significant morbidity and mortality, especially among children and older adults. Vaccination campaigns have played a vital role in reducing pneumococcal-related deaths. However, obstacles related to accessibility and awareness might impede optimal vaccine adoption. This study aims to provide comprehensive data on pneumococcal vaccine coverage and attitudes within at-risk groups in Italy, with the goal of informing public health strategies and addressing vaccination barriers. METHODS: Between April 11 and May 29, 2022, a questionnaire investigating vaccine uptake and attitudes toward several vaccinations was administered to 10,000 Italian adults, chosen through population-based sampling. Respondents who were targets of the campaign according to the 2017-2019 National Vaccination Plan, accessed questions regarding pneumococcal vaccination. Data on uptake, awareness of having the right to free vaccination, opinion on vaccine safety, concern with pneumococcal disease, and ease of access to vaccination services were summarized and presented based on statistical regions. Multinomial logistic regression analysis was used to explore factors influencing vaccine uptake. RESULTS: Out of 2357 eligible adult respondents (42.6% women; mean age: 58.1 ± 15.7), 39.5% received pneumococcal vaccination. Uptake differed among at-risk groups: respondents aged ≥65 (33.7%), with lung disease (48.4%), cardiovascular disease (46.6%), and diabetes (53.7%). Predictors of not being vaccinated and unwilling to included female gender, residing in rural areas, lower education, low concern about pneumococcal disease, vaccine safety concerns, and associations with vaccine-opposed acquaintances. Health access issues predicted willingness to be vaccinated despite non-vaccination. Pneumopathy, heart disease, diabetes, and living in Northeastern or Central Italy were linked to higher uptake. Among the 1064 parents of eligible children, uptake was 79.1%. Parental unawareness of children's free vaccination eligibility was a predictor of non-vaccination. Vaccine safety concerns correlated with reluctance to vaccinate children, while perceived healthcare access challenges were associated with wanting but not having received vaccination. CONCLUSIONS: Pneumococcal vaccination uptake within prioritized groups and children in Italy remains inadequate. Scarce awareness of vaccine availability and obstacles in accessing vaccinations emerge as principal barriers influencing this scenario.

Introduction: The COVID-19 pandemic had a profound impact on vaccines' Research and Development, on vaccines' market, and on immunization programmes and policies. The need to promptly respond to the health emergency boostered resources' al-location and innovation, while new technologies were made available. Regulatory procedures were revised and expedited, and global production and distribution capacities significantly increased. Aim of this review is to outline the trajectory of research in vaccinology and vaccines' pipeline, highlighting major challenges and opportunities, and projecting future perspectives in vaccine preventables diseases' prevention and control. Study Design: Narrative review. Methods: We comprehensively consulted key biomedical databases including "Medline" and "Embase", preprint platforms, including"MedRxiv" and "BioRxiv", clinical trial registries, selected grey literature sources and scientific reports. Further data and insights were collected from experts in the field. We first reflect on the impact that the COVID-19 had on vaccines' Research and Development, regulatory frameworks, and market, we then present updated figures of vaccines pipeline, by different technologies, comparatively highlighting advantages and disadvantages. We conclude summarizing future perspectives in vaccines' development and immunizations strategies, outlining key challenges, knowledge gaps and opportunities for prevention strategies. Results: COVID-19 vaccines' development has been largely supported by public funding. New technologies and expetited autho-rization and distribution processes allowed to control the pandemic, leading vaccines' market to grow exponentially. In the post-pandemic era investments in prevention are projected to decrease but advancements in technology offer great potential to future immunization strategies. As of 2023, the vaccine pipeline include almost 1,000 candidates, at different Research and Development phase, including innovative recombinant protein vaccines, nucleic acid vaccines and viral vector vaccines. Vaccines' technology platforms development varies by disease. Overall, vaccinology is progressing towards increasingly safe and effective products that are easily manufacturable and swiftly convertible. Conclusions: Vaccine research is rapidly evolving, emerging technologies and new immunization models offer public health new tools and large potential to fight vaccines preventables diseases, with promising new platforms and broadened target populations. Real-life data analysis and operational research is needed to evaluate how such potential is exploited in public health practice to improve population health.

Background: Asbestos is a foremost occupational carcinogen globally. Despite the prohibition under Law 257/1992, Italy persists as one of the European nations most burdened by asbestos-related diseases (ARDs). This research assessed ARD cases in asbestos-exposed workers from the Province of Palermo, Italy, spanning 2010-2021. Methods: Data acquisition utilized the epidemiological dataset from the 'Service of Prevention and Safety on Work Environment' under the Prevention Department of Palermo's Local Health Authority (LHA). Results: Between 2010 and 2021, we identified 245 ARD instances, comprising 163 Asbestosis/Pleural plaques, 41 Lung Cancers, 38 Mesotheliomas, and 3 unspecified cases. Multivariate analysis indicated a notable decline in temporal exposure for mesothelioma (HR=0.933; 95% CI=0.902-0.965) and lung cancer (HR=0.93; 95% CI=0.90-0.978) relative to pleural plaques/asbestosis. Tobacco use displayed a pronounced correlation with lung cancer (smoker HR=64.520 95% CI=13,075-318.390; former smoker HR=20.917 95% CI=4,913-89.048). A significant link was observed between mesothelioma and pleural plaques/asbestosis in those employed in shipbuilding and repair (HR=0.371 95% CI=0.155-0.892). Conclusions: ARDs persist in clinical observations, even following the 1992 cessation of asbestos-related activities, emphasizing an enduring public health challenge. Enhancing prevention strategies is paramount, focusing on amplifying anamnestic and occupational data collection, thereby facilitating superior early diagnosis strategies for these maladies in the occupationally exposed cohort.

The European Synchrotron Radiation Facility (ESRF) has recently commissioned the new Extremely Brilliant Source (EBS). The gain in brightness as well as the continuous development of beamline instruments boosts the beamline performances, in particular in terms of accelerated data acquisition. This has motivated the development of new access modes as an alternative to standard proposals for access to beamtime, in particular via the "block allocation group" (BAG) mode. Here, we present the recently implemented "historical materials BAG": a community proposal giving to 10 European institutes the opportunity for guaranteed beamtime at two X-ray powder diffraction (XRPD) beamlines-ID13, for 2D high lateral resolution XRPD mapping, and ID22 for high angular resolution XRPD bulk analyses-with a particular focus on applications to cultural heritage. The capabilities offered by these instruments, the specific hardware and software developments to facilitate and speed-up data acquisition and data processing are detailed, and the first results from this new access are illustrated with recent applications to pigments, paintings, ceramics and wood.

BACKGROUND: Vaccination of healthcare workers (HCWs) reduces the risk of occupational vaccine-preventable diseases (VPDs), prevents their nosocomial transmission and preserves healthcare delivery during outbreaks. Extensive implementation of vaccination programmes for HCWs allowed the elimination or control of several VPDs within healthcare facilities; despite these, the vaccine adherence rates among HCWs are persistently suboptimal. METHODS: A questionnaire was self-administered by HCWs to assess their vaccination rates against several VPDs and self-reported immunity in two university hospitals of Southern Italy (Catania and Palermo). RESULTS: A total of 2586 questionnaires were analysed. More than 50% of HCWs did not know their own immunization status against diphtheria, tetanus and pertussis. More than half of the HCWs interviewed at University Hospital (UH) of Catania (UHC) was immune against measles (72.1%), in contrast with data reported at the UH of Palermo (UHP) (45.9%). Immunization status against mumps (67.5% UHC vs. 40.6% UHP), rubella (69.9% UHC vs. 46.6% UHP) and varicella (70.4% UHC vs. 50.7% UHP). Overall, about 30% of HCWs did not know their own immunization status against these VPDs. Moreover, 84.2% at UHC and 66.7% at UHP stated that was previously vaccinated against hepatitis B. CONCLUSION: Vaccination coverage rates reported from the HCWs against influenza during the last three seasons were considerably low. In conclusion, totally inadequate vaccination rates against several VPDs were found in two university hospitals in Sicily, in terms of preventing not only disease transmission by susceptible HCWs, but also nosocomial outbreaks, confirming data from previous national and international studies.

ESCULAPIO Project, funded by the Centre for Disease Prevention and Control (CCM) of the Italian Ministry of Health, for the program 2013, aims at increasing awareness on vaccine preventable infectious diseases (VPID) and vaccination in different targets of population and at spreading the culture of prevention by the development of information/training interventions on VPID. In Tuscany Region (Central Italy), educational courses on VPID in high schools were organized and students were stimulated to prepare informative materials on VPID for lower grade school pupils. Educational games for school pupils were realized in Liguria Region (Northern Italy) with the aim to increase awareness and knowledge of vaccination among primary school children, their families, and teachers. The Sicilian Operative Unit (OU) developed and validated a questionnaire to collect data on the main factors influencing vaccine uptake in a population from Southern Italy and spreading information on vaccines to the general population. Aim of the activities performed in Apulia Region (Southern Italy) was to collect, directly from the public, a set of issues to which people were more "sensitive," in order to perceive the dimension of informative needs and the misinformation in the field of vaccinations. A toll-free telephone line to answer questions on VPID was also the aim of the Apulian activities. The objective of the OU of Sardinia (Southern Italy) was to increase knowledge on VPID and adherence to immunization campaigns in health care workers (HCW) by realizing traditional and e-learning training courses and initiatives of health promotion in healthcare and hospital setting. Interventions to promote vaccinations in maternal and child health services and outreach interventions in case of parental non-compliance with vaccination schedules were performed in the Veneto Region (Northern Italy), with the aim to reach a particular subgroup of the general population: new or future parents. The activities of Veneto Region aimed also at realizing individual interviews with parents and/or home visit, if considered useful, for families not respondents to the active ordinary call.

The spread of Streptococcus pneumoniae within families has been scarcely investigated so far. This feasibility study aimed to estimate the prevalence of pneumococcal carriage in school-aged children and co-habiting relatives and to explore the potential link between the family environment and the sharing of pneumococcal serotypes covered by the vaccine. Oropharyngeal samples of 146 subjects belonging to 36 different family groups were molecularly tested for pneumococcal detection and serotyping. The overall prevalence of pneumococcal carriage was 65.8% (n = 96/146), whereas it was higher among schoolchildren (77.8%, n = 28/36); subjects of seven years of age had the highest odds of being colonized (odds ratio, OR = 5.176; p = 0.145). Pneumococcal serotypes included in the 13-valent conjugate vaccine formulation were largely detected in the study population and multiple serotypes colonization was considerable. Factors relating to a close proximity among people at the family level were statistically associated with pneumococcal carriage (OR = 2.121; p = 0.049), as well as active smoking habit with a clear dose-response effect (ORs = 1.017-3.326). About half of family clusters evidenced similar patterns of carried pneumococcal serotypes and the odds of sustaining a high level of intrafamilial sharing increased with household size (ORs = 1.083-5.000). This study highlighted the potential role played by the family environment in sustaining both the circulation and horizontal transmission of pneumococcus.

Following two invasive meningococcal disease cases among twenties, general population overloaded vaccination Units of the Palermo's District during summer 2016. Sicilian Health Authorities adopted several public health strategies including: a) active meningococcal vaccination free of charge for people from 18 up to 30 years of age, b) information in crowded places and rapid communication by media. An increase in anti-meningococcal vaccination doses administered (+868%) as well as in anti-dTp and HPV vaccination (+41% and +8%, respectively) due to a further catch-up was observed.

BACKGROUND: Although influenza vaccination has been demonstrated to be safe and effective, vaccination coverage rates among health care workers and among medical residents appear generally low. Several investigations have been performed worldwide to analyze the healthcare workers' educational deficiencies. This multicentre survey aimed to investigate at a nationwide level training quality and work environment associated with seasonal influenza vaccination uptake among Italian medical residents. METHODS: A retrospective cohort study was carried out from April 2012 to June 2012 on medical residents regularly attending the post-graduate medical schools of 18 Italian Universities via an anonymous, self administered, web-based questionnaire. Data have been analyzed by using the R statistical software package. RESULTS: A total of 2506 out of 10,854 medical residents (23.1%) have been recruited. The quality of training on influenza and influenza vaccination was reported as "fair" or "poor" during both pre-graduate (40.7% of respondents) and post-graduate medical school (59.6% of respondents). Vaccination uptake was associated with adherence to seasonal 2011/2012 influenza vaccination of medical school tutors (adjusted OR = 4.4; 95% CI = 1.35-14.26) and other medical residents (adjusted OR = 2.2; 95% CI = 1.14-4.23). Moreover, influenza vaccination uptake was also associated with correct knowledge about the virus composition of 2011/2012 influenza vaccine (adjusted OR = 2.43; 95% CI = 1.64-2.58) and consultation of scientific sources or Institutional recommendations on influenza vaccination (adjusted OR = 6.96; 95% CI = 3.38-214.36). CONCLUSIONS: Medical residency represents an opportunity to implement educational and training interventions aiming to promote appropriate professional behaviors and skills. Our study suggest that appropriate training, adequate education and proactive coworkers feelings can improve influenza vaccination attitudes towards young doctor.

Molecular epidemiology of influenza B virus remained poorly studied in Italy, despite representing a major contributor to seasonal epidemics. This study aimed to reconstruct the phylogenetic relationships and genetic diversity of the hemagglutinin gene sequences of 197 influenza B strains circulating in both Southern (Sicily) and Northern (Liguria) Italy between 2010 and 2015. Upper respiratory tract specimens of patients displaying symptoms of influenza-like illness were screened by real-time RT-PCR assay for the presence of influenza B virus. PCR-positive influenza B samples were further analyzed by sequencing. Neighbor-joining phylogenetic trees were constructed and the amino-acid alignments were analyzed. Phylogenetic analysis showed clusters in B/Victoria clade 1A/1B (n = 29, 14.7%), and B/Yamagata clades 2 (n = 112, 56.8%) and 3 (n = 56, 28.4%). Both influenza B lineages were found to co-circulate during the study period, although a lineage swap from B/Victoria to B/Yamagata occurred in Italy between January 2011 and January 2013. The most represented amino-acid substitutions were N116K in the 120-loop (83.9% of B/Yamagata clade 3 strains) and I146V in the 150-loop (89.6% of B/Victoria clade 1 strains). D197N in 190-helix was found in almost all viruses collected. Our findings provide further evidence to support the adoption of quadrivalent influenza vaccines in our country.

OBJECTIVES: to assess the trends of foodborne diseases in respect of the abolition of food handler certification by Italian Regions. DESIGN: rates of foodborne diseases recorded before and after the abolition of food handler certification were compared. SETTING AND PARTICIPANTS: the study included notifications collected in Italy through the national infectious disease surveillance system between 1996 and 2009. MAIN OUTCOME MEASURES: annual rates of seven main foodborne diseases. RESULTS: a significant reduction in notifications of foodborne diseases occurred in most Italian Regions in the years after the abolition of the food handler certification. CONCLUSIONS: the abolition of food handler certification coincided with no increase in the overall estimated incidence of foodborne diseases in the Italian population. Furthermore, the temporal and spatial patterns of notification rates suggest the possibility that other key factors have contributed to this result, including the heterogeneity of the surveillance system performance.

BACKGROUND: ESCULAPIO is a multicenter project, funded by the Italian Centre for Disease Prevention and Control, aimed at implementing communication strategies to improve vaccination knowledge and attitudes among different target populations. OBJECTIVE: The objective of the Sicilian research unit was, in the first phase, to identify, through systematic literature revision, which vaccination determinants play a role in the uptake of recommended vaccines included in the Italian Vaccination Plan. DESIGN: A systematic literature review was carried out on studies describing the determinants underlying pneumococcal and meningococcal vaccination uptake. The analysis was limited to papers published in English from 2000 to date. RESULTS: A total of 188 (meningococcal) and 731 (pneumococcal) papers were found. After selection by publication data, country (Europe), article type (original article), target population (healthy subjects), 7 (meningococcal) and 4 ( pneumococcal) manuscripts were finally included in the analysis. For meningococcal vaccination a better socioeconomic status is related to vaccination acceptance, whereas distance from immunization service is a negative determinant. For pneumococcal vaccination the determinants related to vaccination uptake are older parental age and a strong vaccine recommendation. Conversely, when the vaccine needs to be paid for, a refusal is more likely. CONCLUSIONS: Our results show that payment for vaccination is a major barrier and communication about meningococcal and pneumococcal vaccination should be targeted towards specific population groups, especially through the counseling activities by health professionals.

BACKGROUND: Among health care workers (HCWs), work-related stress is one of the main topics in risk assessment and prevention at the workplace. Post-graduate medical residents (MRs) are a group of HCWs comparable to medical doctors in terms of occupational exposure and occurrence of work-related stress syndromes. OBJECTIVES: Risk assessment of work-related stress among MRs attending the major University Hospital of Sicily. METHODS: A cross-sectional survey via an anonymous and self-administered questionnaire. RESULTS: 45% of clinical MRs and 37% of surgical MRs had access to compensatory rest days against 92% of MRs of the services area (p<0.001). A work attendance recording system for MRs was available in 80% of the postgraduate medical schools of the services area, in 60% of the clinical postgraduate schools and in 50% of the surgical postgraduate schools (p<0.001). MRs of the postgraduate surgical schools reported having access to work breaks (41%) with less frequency compared to clinical (60%) and services MRs (74%) (p<0.001). Both clinical (47%) and surgical MRs (47%) were more exposed to work-related stress than MRs of the services area (27%) (p<0.001). CONCLUSIONS: The survey demonstrated excess exposure to work-related stress for all the considered variables in MRs of the surgical area, compared with MRs of clinical and services areas. It is strongly recommended to provide specific training programmes aimed at managing the MRs' risk of exposure to work-related stress, focusing both on the workers and the work environment.

During March 2011 an outbreak of gastroenteritis occurred in Santo Stefano di Quisquina, Agrigento, Sicily, Italy. Within two weeks 156 cases were identified among the 4,965 people living in the municipality. An epidemiological investigation was conducted to characterize the outbreak and target the control measures. A case was defined as a person developing diarrhea or vomiting during February 27-March 13, 2011. Stool specimens were collected from 12 cases. Norovirus (NoV) genotype GII.4 variant New Orleans 2009 was identified in stool samples from 11 of 12 cases tested (91.7%). Epidemiological investigations suggested a possible association with municipal drinking water consumption. Water samples from the public water system were tested for NoV and a variety of genotypes were detected during the first 3 months of surveillance, including GII.4 strains belonging to different variants from that involved in the gastroenteritis outbreak. Contamination of the well and springs supplying the public water network was eventually thought to be the source of the NoV contamination.

OBJECTIVE: To evaluate the characteristics of hospital discharge diagnoses of influenza measured by using specific International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9 CM) codes. SUBJECTS AND METHODS: The study was conducted for the 3 years 2007, 2008 and 2011. The database included (1) administrative and clinical data on Sicilian patients admitted to acute care hospitals and (2) data from the influenza virological surveillance of 10 European countries (FluNet database). All Sicilian patients diagnosed with at least 1 ICD-9 CM code for influenza (487.0, 487.1 and 487.9) were considered influenza cases. RESULTS: Overall, 2,880 patients with an ICD-9 CM code attributable to influenza were hospitalized in Sicily: 2,119 (73.6%) were admitted from November to April, whereas 761 (26.4%) were admitted from May to October. In the 3 years studied, the analyzed European influenza surveillance systems recorded a peak of laboratory-confirmed influenza activity from November to April with 36,753 (99.7%) influenza cases, whereas only 124 cases (0.3%) were observed from May to October. CONCLUSIONS: In Sicily, more than one quarter of all hospital admissions with an ICD-9 CM code for influenza were observed in the months with a negligible circulation of influenza viruses. Our findings show that several hospital discharge records included ICD-9 CM codes for influenza with low levels of sensitivity, specificity and/or appropriateness for clinical information and support the need for improving medical education on the epidemiology and hospital management of influenza cases.

INTRODUCTION: The Italian Committee of medical residents in Hygiene, Preventive Medicine and Public Health is a member of the Italian Society of Hygiene, Preventive Medicine and Public Health with the aim of developing a network among Italian resident in public health and promoting the educational path improvement through comparisons and debates between postgraduate medical schools. In this perspective, during last years account has been taken of some essential topics concerning education of public health medical residents, which represent future health-care and public health experts. METHODS: Cross-sectional researches were conducted among Italian public health medical residents (PHMRs) through self-administered and web-based questionnaires. Each questionnaire was previously validated by pilot studies conducted during the 46th National Conference of the Italian Society of Hygiene, Preventive Medicine and Public Health. RESULTS: Seventy percent of Italian PHMRs considered the actual length of Public Health postgraduate medical school excessively long, with regard to predetermined educational goals. Confirming this statement, 90% of respondents were inclined to a reduction from 5 to 4 years of postgraduate medical school length, established by Law Decree 104/2013. Seventy seven percent of surveyed PHMRs stand up for a rearrangement on a national setting of the access contest to postgraduate medical schools. Moreover 1/3 of Italian schools performed less than 75%of learning and qualifying activities specified in Ministerial Decree of August 2005. In particular, data analysis showed considerable differences among Italian postgraduate schools. Finally, in 2015 only four Italian Universities (Napoli Federico II, Palermo, Pavia, Roma Tor Vergata) provide for the Second Level Master qualify for the functions of occupational doctor. This offer makes available 60 positions against a request of over 200 future Public Health medical doctors who have shown interest in the Master. CONCLUSIONS: In Italy, after the introduction of Ministerial Decree 285/2005, the educational course of PHMRs was significantly improved. The standardization of learning and qualifying activities allowed for the first time the attendance at medical directions or Local Health Units. Nevertheless, the excessive lenght of postgradute schools and the differences about training among Italian Universities are critical and actual issue. Moreover, the remarkable interest shown by PHMRs in the Master could suggest a poor job replacement prospect for young medical specialist in Hygiene, Preventive Medicine and Public Health.

The current influenza season started in Italy in October 2023, approaching the epidemic peak in late December (52nd week of the year). We aimed to explore the mid-term virologic surveillance data of the 2023/2024 influenza season (from 16 October 2023 to 7 January 2024) in Sicily, the fourth most populous Italian region. A test-negative design was used to estimate the effectiveness of seasonal influenza vaccine (VE) against A(H1N1)pdm09 virus, the predominant subtype in Sicily (96.2% of laboratory-confirmed influenza cases). Overall, 29.2% (n = 359/1230) of oropharyngeal swabs collected from patients with influenza-like illness (ILI) were positive for influenza. Among the laboratory-confirmed influenza cases, 12.5% (n = 45/359) were vaccinated against influenza, with higher prevalence of laboratory-confirmed diagnosis of influenza A among subjects vaccinated with quadrivalent inactivated standard dose (29.4%), live attenuated intranasal (25.1%), and quadrivalent inactivated high-dose (23.8%) influenza vaccines. Comparing influenza vaccination status for the 2023/2024 season among laboratory-confirmed influenza-positive and -negative samples, higher vaccination rates in influenza-negative samples (vs. positive) were observed in all age groups, except for 45-64 years old, regardless of sex and comorbidities. The overall adjusted VE (adj-VE) was 41.4% [95%CI: 10.5-61.6%], whereas the adj-VE was 37.9% [95%CI: -0.7-61.7%] among children 7 months-14 years old and 52.7% [95%CI: -38.0-83.8%] among the elderly (≥65 years old).
RESUMEN
Monitoring the genetic variability of human respiratory syncytial virus (hRSV) is of paramount importance, especially for the potential implication of key antigenic mutations on the emergence of immune escape variants. Thus, to describe the genetic diversity and evolutionary dynamics of hRSV circulating in Sicily (Italy), a total of 153 hRSV whole-genome sequences collected from 770 hRSV-positive subjects between 2017 and 2023, before the introduction of expanded immunization programs into the population, were investigated. The phylogenetic analyses indicated that the genotypes GA.2.3.5 (ON1) for hRSV-A and GB.5.0.5a (BA9) for hRSV-B co-circulated in our region. Amino acid (AA) substitutions in the surface and internal proteins were evaluated, including the F protein antigenic sites, as the major targets of immunoprophylactic monoclonal antibodies and vaccines. Overall, the proportion of AA changes ranged between 1.5% and 22.6% among hRSV-A, whereas hRSV-B varied in the range 0.8-16.9%; the latter was more polymorphic than hRSV-A within the key antigenic sites. No AA substitutions were found at site III of both subgroups. Although several non-synonymous mutations were found, none of the polymorphisms known to potentially affect the efficacy of current preventive measures were documented. These findings provide new insights into the global hRSV molecular epidemiology and highlight the importance of defining a baseline genomic picture to monitor for future changes that might be induced by the selective pressures of immunological preventive measures, which will soon become widely available.

DTaP5-HBV-IPV-Hib (Vaxelis®) is a hexavalent combination vaccine (HV) indicated in infants and toddlers for the prevention of diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis, and invasive disease due to Haemophilus influenzae type b. Switching between HVs during the childhood vaccination series is sometimes necessary due to, for example, vaccine availability, health-care provider preference, and/or tender awards. The purpose of this study was to describe the safety, tolerability, and immunogenicity of a booster dose of Vaxelis® in participants who previously received a primary infant series of either DTaP2-HBV-IPV-Hib (Hexyon®) or Vaxelis®. Healthy participants approximately 11-13 months of age who previously received a two-dose primary series of Hexyon® (HHV group) or Vaxelis® (VVV group) all received a Vaxelis® booster dose. Immunogenicity was evaluated by measuring antibody levels to individual vaccine antigens approximately 30 days following booster vaccination. Safety was evaluated as the proportion of participants with adverse events (AEs). The proportions of participants with antibody-specific responses for antigens contained in both Vaxelis® and Hexyon® at 30 days post-toddler-booster vaccination with Vaxelis® were comparable between groups, and higher in the VVV group for Vaxelis® antigens PRN and FIM2/3. The overall proportions of participants with AEs were generally comparable between groups. Following a booster dose of Vaxelis®, immune responses were comparable between groups for all shared antigens, and higher in the VVV group for antigens found only in Vaxelis®. The booster was well tolerated in both groups. These data support the use of Vaxelis® as a booster in mixed HV regimens.
