Monkeypox Virus Infections in Southern Italy: Is There a Risk for Community Spread?

The ongoing outbreak of the Monkeypox virus (MPXV) is characterized by sustained human-to-human transmission, particularly among men who have sex with men (MSM). The aim of the study was to describe the characteristics of the MPXV infection identified in Southern Italy. Clinical samples for each suspected case identified from 1 June to 1 August 2022 were tested for MPXV, and whole-genome sequencing (WGS) was performed on two strains.

Social Media Interventions Strengthened COVID-19 Immunization Campaign.

Background: Since The Italian Medicines Agency (AIFA) has recommended the COVID-19 vaccine Comirnaty in children aged 5-11, the immunization campaign faced vaccine hesitancy in parents. Social media are emerging as leading information source that could play a significant role to counteract vaccine hesitancy, influencing parents' opinions and perceptions. Our aim was to evaluate the coverage of the COVID-19 vaccine Comirnaty in a cohort of children aged 5-11 whose families have been counseled to use Social Media to counteract vaccine hesitancy.

Post-Marketing Active Surveillance of Adverse Reactions Following Influenza Cell-Based Quadrivalent Vaccine: An Italian Prospective Observational Study.

Since the influenza season 2018/19, the Italian Ministry of Health recommended a dose of cell-based quadrivalent vaccine (Flucelvax Tetra) for HCWs (healthcare workers), because this vaccine seemed more efficacious in the prevention of AH3N2 virus. Due to the lack of pre-registration data, the safety profile of this new vaccine must be investigated in post-marketing surveillance. The aim of our study is to evaluate, through a post-marketing active surveillance program developed during the 2019/20 influenza season, any Adverse Events Following Immunization (AEFIs) that happened in the 7 days after immunization with Flucelvax Tetra.

Long-term immunogenicity after measles vaccine vs. wild infection: an Italian retrospective cohort study.

The persistence of specific IgG after measles infection and after measles vaccination has not been sufficiently investigated. Current evidence suggests that immunity after the disease is life-long, whereas the response after two doses of measles-containing vaccine declines within 10-15 years. This study evaluated the proportion of individuals with detectable anti-measles IgG in two groups, those vaccinated with two doses of anti-MMR vaccine and those with a self-reported history of measles infection.

[Integrated management method in the prevention department of a COVID-19 epidemic outbreak in a large meat processing plant in Bari province].

Aim of this paper is to describe the management of an outbreak of COVID-19 in a slaughtering and meat processing plant in Bari Province (Southern Italy). At the end of the outbreak investigation, 18.4% of the employees were positive to the molecular test for SARS-CoV-2.

Resources for assessing parents' vaccine hesitancy: a systematic review of the literature.

The concept of Vaccine Hesitancy has begun to appear in the scientific landscape, referring to the reluctance of a growing proportion of people to accept the vaccination offer. A variety of factors were identified as being associated with vaccine hesitancy but there was no universal algorithm and currently there aren't any established metrics to assess either the presence or impact of vaccine hesitancy. The aim of this study was to systematically review the published questionnaires evaluating parental vaccine hesitancy, to highlight the differences among these surveys and offer a general overview on this matter.

Vaccination coverage among paediatric onco-haematological patients: an Italian cross-sectional study.

Children with onco-hematological diseases are at increased risk of infection. However, this risk can in part be controlled or reduced using currently available vaccines. Despite available evidence, in patients diagnosed with a hematological or oncological disease the vaccination schedule is often inappropriately discontinued.

Prevalence and management of measles susceptibility in healthcare workers in Italy: a systematic review and meta-analysis.

Introduction: The national and international guidelines recommend evaluating all healthcare workers (HCWs) for their measles immune status and possibly vaccinating those who are seronegative.

Areas Covered: We conducted a systematic review and meta-analysis in order to estimate the rate of measles susceptibility among HCWs in Italy and to explore possible options for the management of those found to be susceptible. Twenty-three studies were included in the meta-analysis.

Long time persistence of antibodies against Mumps in fully MMR immunized young adults: an Italian retrospective cohort study.

Protective levels of antibodies induced by the MMR vaccine have been shown to decline over time, but actually there is not a formal recommendation about the opportunity of testing immunized HCWs to investigate the persistence of anti-Mumps IgG. This study aims to evaluate the long-time immunogenicity of MMR vaccination in a sample of medical students and residents of the University of Bari who attended the Hygiene Department for the biological risk assessment (April 2014-June 2018). A strategy for the management of non-responder subjects has been experimented and described.

Post-marketing surveillance of adverse events following measles, mumps, rubella and varicella (MMRV) vaccine: retrospecive study in apulia region (ITALY), 2009-2017.

Since 2006, some Italian Regions introduced the active offer of measles, mumps, rubella, and varicella (MMRV) vaccine for all newborns during the second years of life. In 2011, Italian Drug Authority (AIFA) recommended the discontinuation of the MMRV use for an increased risk of febrile seizures following vaccination; furthermore, some Regions (such as Apulia, that introduced MMRV offer in 2009) chose to continue the use of MMRV and Ministry of Health recommended to guarantee supplemental monitoring of safety of the vaccine. In Italy, the surveillance of Adverse Events following immunization (AEFIs) is currently carried out by AIFA and Regional Health Authorities; this paper aims to summarize the results of MMRV-vaccine surveillance of AEFIs program carried out in Apulia.

Compliance with immunization and a biological risk assessment of health care workers as part of an occupational health surveillance program: The experience of a university hospital in southern Italy.

Background: The active immunization of health care workers (HCWs) is a primary measure to prevent nosocomial infection; despite this, vaccine coverage among HCWs in most countries is low. To increase vaccine coverage in the health care setting, the hygiene and occupational medicine departments of Bari Policlinico General University-Hospital implemented a vaccination procedure. This operative procedure requires that during the occupational medical examination, all employees are evaluated for immunity/susceptibility to vaccine-preventable diseases, with vaccination offered to those determined to be susceptible.

Immunity to rubella: an Italian retrospective cohort study.

Background: International guidelines recommend that healthcare workers (HCWs) have presumptive evidence of immunity to rubella and that susceptible HCWs and doubt cases receive two doses of the MMR vaccine. However, a small percentage of the fully immunized will remain unprotected against wild viruses. Moreover, protective levels of antibodies induced by the vaccine have been shown to decline over time, but a formal recommendation regarding the testing of immunized HCWs for the persistence of IgG against rubella is lacking.

Epidemiology of injuries among amateur athletes who attended fitness activities: the role of the qualification of the trainer.

Background: The fitness trainer could have an important role in the prevention of injuries among fitness attendants. In several Countries, including Italy, there is not a formal regulation about the qualification of fitness trainers. The aim of our study is to estimate the incidence of injuries in a sample of amateur fitness athletes training in Apulia (southern Italy) and evaluate if being the presence of a trainer graduated in Sports and Movement Science could be a protective factor for injuries.

Adverse Events Following Measles-Mumps-Rubella-Varicella Vaccination and the Case of Seizures: A Post Marketing Active Surveillance in Puglia Italian Region, 2017-2018.

Since 2012, the Italian Ministry of Health has recommended to improve the surveillance of adverse events following the measles-mumps-rubella-varicella (MMRV) tetravalent vaccine that was provided in the official immunization schedule of some Italian regions for children during the second year of life. This recommendation was based on data from some surveys that showed an additional risk of seizure following the administration of this vaccine. Responding to the Ministry commitment, the Puglia Region launched, from May 2017 to November 2018, a post-marketing active surveillance program of adverse events following MMRV immunization (AEFIs).

Long-term Immunogenicity of Measles Vaccine: An Italian Retrospective Cohort Study.

Background: Levels of antibodies induced by the measles virus-containing vaccine have been shown to decline over time, but there is no formal recommendation about testing immunized subjects (in particular, healthcare workers [HCWs]) to investigate the persistence of measles immunoglobulin G (IgG).

Methods: This study aims to evaluate the long-term immunogenicity of measles vaccine in a sample of medical students and residents of the University of Bari who attended the Hygiene Department for a biological risk assessment (April 2014-June 2018).

Results: Two thousand immunized (2 doses of measles-mumps-rubella [MMR] vaccine) students and residents were tested; 305 of these (15%) did not show protective anti-measles IgG.

Influenza vaccination in health-care workers: an evaluation of an on-site vaccination strategy to increase vaccination uptake in HCWs of a South Italy Hospital.

Despite the international recommendation and specific programs, and although the vaccination of health-care workers (HCWs) is considered the main measure to prevent nosocomial influenza, vaccination coverage (VC) among HCWs remains low. One of the most important barriers to vaccination uptake is the time required to attend a vaccination clinic. Centers for Disease Control and Prevention (CDC) recommends on-site influenza vaccination as a proven and cost-effective strategy that increases productivity, reduces overall absenteeism and prevents direct health-care costs.

Influenza vaccination coverage among splenectomized patients: an Italian study on the role of active recall in the vaccination compliance.

Patients with anatomical or functional hypo-/a-splenia have a 10- to 50-fold higher risk of developing severe infectious diseases than does the general population. Thus, it is recommended to adhere to a specific vaccination schedule, including receiving influenza vaccine. During 2014, Bari Policlinico General Hospital approved a specific protocol to ensure that vaccines are actively offered to all splenectomized patients during their hospitalizations.

Vaccination coverage in patients affected by chronic diseases: A 2014 cross-sectional study among subjects hospitalized at Bari Policlinico General Hospital.

Subjects affected by at least 1 chronic disease are the target of influenza vaccination strategies because they are at high risk of influenza complications or death. The aim of this cross-sectional study is to evaluate flu and pneumococcal vaccination coverage (VC) in a sample of patients hospitalized at Bari Policlinico General Hospital (South Italy). According to national public health guidelines, these patients should have been vaccinated at hospital discharge by general practitioners.
