[The importance of flu vaccination during CoViD time].

In the next months, the risk of coinfection with f lu virus and Sars-CoV-2 is high. Despite the number of studies dealing with the consequences of the interaction between the two viruses, the impact of this coexistence on human health is still uncertain. However, achieving high f lu vaccination coverage would mean avoiding hospital overload due to hospitalizations for f lu complications and facilitating a timely differential diagnosis that allows a quick and appropriate treatment of CoViD-19 cases.

[Routine vaccinations during SARS-CoV-2 epidemics].

The circulation of SARS-CoV-2 required the deplacement of resources from routine preventive activities to pandemic-related interventions. The vaccination services have been adapted to the individual territorial realities on the basis of virus circulation and restrictive measures put in place. The reduction of coverage with the consequent accumulation of susceptible subjects increases the risk of vaccine-preventable diseases' epidemics.

Healthcare Workers Training Courses on Vaccinations: A Flexible Format Easily Adaptable to Different Healthcare Settings.

Since 2017, Italy has expanded the compulsory vaccination from 4 to 10 for those aged 0 to 16 years. Because of the great organizational effort required for the immunization services, minor attention was given to the vaccinations not included among the mandatory ones. This situation led to a real difficulty in harmonizing the vaccination procedures even inside a single region.

[Vaccines: from the identification of the microorganism to marketing. How long does it take?].

The development of a vaccine, particularly one that can help against the recent pandemic, is a topic that has recently attracted public opinion. More than ninety vaccines are currently being developed against Sars-Cov2 by universities and companies around the world. They are protein-based vaccines, viral vector vaccines, DNA or RNA vaccines and inactivated or attenuated viral vaccines.

[Tuberculosis: an ever present disease but difficult to prevent].

Tuberculosis (TB) is an infectious and contagious disease caused by Mycobacterium tuberculosis, commonly called Koch's bacillus. TB is spread by air and is present all over the world. Not everyone who become infected develop the disease; the immune system can cope with the infection and the bacterium can remain dormant for years.

Opinions and attitudes of Italian healthcare workers towards recommended but not compulsory rotavirus vaccination.

Rotaviruses (RVs) are a leading cause of viral gastroenteritis among children younger than 5. The incidence of RV disease can be reduced through the widespread use of vaccination, but coverage is low in many countries, including Italy. This fact reflects the poor consideration given to the RV vaccine, both by the population and by healthcare workers.

Strategies for elimination of rubella in pregnancy and of congenital rubella syndrome in high and upper-middle income countries.

Rubella infection generally leads to mild symptoms; otherwise, in pregnant women it can cause severe damages. The only way to prevent rubella is vaccine. Before the introduction of the vaccine, up to 4 babies in 1000 live births were born with CRS.

[Old outbreaks and new vaccines: Italy facing Ebola].

Zaire is the name of the most deadly Ebola Virus (ZEBOV), which caused many outbreaks in past years and is the causative agent of the most recent one. In July 2019, Ebola was declared a public health emergency of international concern. After this declaration, the steps required to prequalify and approve the r VSV ZEBOV vaccine followed each other quickly.

[Anti-flu Vaccine: tailor made solutions in large-scale distribution].

Influenza is a public health problem with a strong impact from an epidemiological, clinical and economic point of view. Many factors contribute: ubiquity and contagiousness of the disease, antigenic variability of the viruses and the possibility of serious complications. Influenza rarely causes complications in healthy subjects.

[Adverse reactions after repeated doses of anti-tetanus vaccine: scientific evidences].

The possible risk of hyperimmunization after tetanus vaccination is currently discussed after the National Vaccine Prevention Plan 2017-2019 confirmed the recommendation of a booster dose every ten years. Due to the ubiquitous nature of tetanus spores and the inability to obtain herd-immunity through vaccination, efforts to reduce the incidence of tetanus aim at eliminating the disease. The only way to prevent infection is vaccination followed by recommended periodic booster doses.

[Anti-pneumococcus, anti-herpes-zoster and anti-papillomavirus vaccinations: experience in programming continuing education courses in local health units in Rome].

The National Vaccine Prevention Plan considers the recommendations for immune prophylaxis in all ages of life. However, compulsory vaccination introduced in 2017 focused the attention on improving global vaccination coverage in infants and children, giving less attention to adult/elderly vaccinations. The immunization of this population is necessary considering the change in the age structure of the population, whose average life expectancy is increasing.

[Influenza prevention in health-care workers: enhancement of the influenza vaccination campaign at Policlinico Tor Vergata in Rome (Italy) during the 2017/2018 epidemic season].

Given the very low influenza vaccination coverage averaging 4% among health-care workers at Policlinico Tor Vergata during the previous epidemic seasons, it was decided to implement a series of interventions to promote influenza vaccination compliance in the current (2017/2018) season. The total number of vaccinated health-care workers at the end of the current season was 364, resulting in a vaccination coverage of approximately 12%. The increase took place in all professional groups, with a coverage of 25% among permanent MDs, 9% among Medical Residents, 3% among nurses and 8% among technicians.

[Epidemics of Hepatitis A and opportunities for vaccination: a focus on the category of men who practice sex with men (MSM)].

Hepatitis A is an infectious disease caused by a virus (HAV), which is highly contagious and widespread all over the world. In industrialized countries, Hepatitis A is commonly considered a disease with an important socio-economic impact, as the clinical disease affects mostly young adults. After the development of a specific anti-HAV vaccine, a reduction in the incidence of Hepatitis A was observed, with a subsequent change in the prevalence of HAV.

[Prevention of vector-borne diseases in Italy].

In recent years, a constant increase of vector-borne diseases has been seen in Italy, due to various conditions including climate change, trade and international travel. These factors contribute to the diffusion on the Italian territory of newly introduced carriers and pathogens. These new pathogens can be an emerging cause of epidemics, as in the case of the Chikungunya virus in 2007 and in 2017, or can establish a true endemic disease, as in the case of the West Nile virus.

[Vaccines and sport: risk perception among athletes].

Infection prevention is a key issue in both general population and in categories at risk, among which the athletes. There are risk factors related to the sporting practice performed at every level, from the amateur to the elite athletes. The control of the vaccination schedule and the empowerment of the sportsman in this area should be carried out both by the General Practitioner or the Pediatrician and by the federations to which the athletes belong.

[Vaccines: benefits have been forgotten].

The increased use of vaccination has led to a significant decrease or even to the disappearance of serious infectious diseases. Currently, vaccines are often evaluated by their potential side effects while ignoring the benefits. This happens because of memory loss.

[Bacterial lysates: history and availability].

The use of bacterial lysates (BLs) can be traced back to the end of the nineteenth century, and they are currently available in several countries across all continents. Over the last few decades, BLs have been used, both in pediatric patients and in adults, mainly for the prevention and treatment of bacterial infections of the respiratory tract. BLs are produced from bacterial cultures that undergo cell lysis with two different methods: mechanical lysis and chemical lysis.

Italian Physicians' Opinions on Rotavirus Vaccine Implementation.

Rotavirus (RV) infection is the main cause of severe acute gastroenteritis (GE) in the pediatric population and has a major impact in both developing and industrialized countries. The reduction of severe RVGE cases, followed by death or hospitalization, is considered the main benefit of RV vaccination, even though its implementation often faces obstacles. In Italy, the recently approved National Immunization Plan aims to overcome the differences among regions, offering a universal free RV vaccination.

[Recall system for vaccinations in preschool children in a Local Health Unit in Rome, Italy].

In Italy, in this period, much attention is dedicated to reach adequate vaccination coverage in children and adolescents. In this study, Vaccination Registry was checked in a Local Health Unit in Rome, Italy, to identify children born in 2007 and 2008 who had not completed the vaccination schedule. Coverage for booster doses of measles, mumps, rubella and for diphtheria, tetanus, pertussis and polio vaccines in the 2213 children was around 70%.

[The Italian Immunization Plan 2017: analysis and starting point for the Regional Plans].

The National Immunization Plan 2017-2019 has been approved on January 2017. This official document contains the new Italian guidelines to improve vaccination coverage in the country. We conducted an accurate and critical analysis of the document, highlighting its key points and critical issues, in order to offer an practical tool for writing the Regional Plans.

Frequently asked questions on seven rare adverse events following immunization.

Routine mass immunization programs have contributed greatly to the control of infectious diseases and to the improvement of the health of populations. Over the last decades, the rise of antivaccination movements has threatened the advances made in this field to the point that vaccination coverage rates have decreased and outbreaks of vaccine-preventable diseases have resurfaced. One of the critical points of the immunization debate revolves around the level of risk attributable to vaccination, namely the possibility of experiencing serious and possibly irreversible adverse events.

[Rare adverse events following immunization: coincidence].

The high standards of safety and effectiveness of vaccines have allowed them to get a prominent role in disease prevention and health protection. However, like any other intervention, vaccination is not free from risks. Rare adverse events occur after immunization in less than one in a thousand individuals and can be linked to vaccination by causality or coincidence.

[Vaccines: history and stories between reality and imagination].

Vaccinations and the controversy around them always go in parallel. We identified four categories blending in various amounts of truth and imagination: history, myths, shams and frauds. Over the years, they have alternated and sometimes transformed into one another.

[Zika virus: a public health overview on epidemiology, clinical practice and prevention].

Zika virus is an arbovirus mainly transmitted by mosquitoes bites. During the last months, the attention of Public Health Institutions has been drawn by a significant increase of microcephaly cases in Brasil and analyses highlighted a connection between Zika virus infection in pregnant women and fetal microcephaly. Since 2015, many Zika virus outbreaks have been identified in South America and there is concern about the spread of the virus in areas where competent vectors are present.
