Active surveillance for safety monitoring of seasonal influenza vaccines in Italy, 2015/2016 season.

BACKGROUND: Surveillance for adverse events following immunization is an important component of any national immunization programme because it is critical to assessing the safety of vaccines and to detecting potentially rare and severe adverse events and responding in a timely manner. We conducted an enhanced active surveillance aimed at assessing the safety of flu vaccines in the 2015-2016 season in Italy. The study was targeted to the population groups for which the seasonal vaccine is recommended in Italy. METHODS: During the study period, a total of 3213 individuals receiving seasonal influenza vaccination were registered on the web-based platform. Any adverse events experienced after 7 days from vaccination by individuals aged six months or more were collected through a telephone interview or by a web-based self-administered questionnaire. All individuals experiencing at least one event during the 7 days of follow-up were contacted for follow-up to 60 days. RESULTS: Overall, 854 events were reported: 845 events (26%) after administration of the first dose and 9 (12%) after the second dose. The majority of adverse events reported after 7 days from the first dose were of little clinical importance, and most involved local symptoms. CONCLUSION: Our data, even though the number of vaccinated individuals was smaller than expected, is consistent with the safety of influenza vaccines in Italy during the 2015-2016 season regarding the most common adverse events. Further efforts are needed to obtain sufficient power to study rarer adverse events. Active monitoring and systematic studies to test generated signals and hypotheses are crucial to intensify awareness among the public and professionals with regard to the safety of vaccines.

Behaviour and eating habits as determinants for human opisthorchiasis in the Bolsena Lake area, Italy.

In Italy, food-borne outbreaks of opisthorchiasis have occurred since 2003, all of them originating from some lakes in Central Italy where the only European liver fluke, Opisthorchis felineus (Rivolta, 1884) is endemic. The aim of the present study is to investigate the factors that may facilitate the life cycle of O. felineus in the area of Bolsena Lake, the knowledge of the local population about opisthorchiasis, and preventative healthcare measures. We performed a descriptive observational study through the submission of questionnaires to three target populations: fishermen who fish exclusively in Bolsena Lake, restaurateurs whose businesses are close to the lake and general population living in the province of Viterbo. Results showed hazardous behaviours and eating habits in the three target populations, as well as a poor knowledge of opisthorchiasis and preventative healthcare measures.

[HPV vaccination: active offer in an Italian region]. / Offerta attiva della vaccinazione anti-HPV nella Regione Lazio.

Human Papillomavirus is responsible for 4.8% of cancers, and is the main cause of cervical cancer. Cervical cancer can be reduced by mean of secondary prevention (PAP-test, HPV-DNA test), while through primary prevention (anti-HPV vaccine) the incidence of other HPV-attributable cancers can also be reduced. In Italy, anti-HPV vaccination is part of the immunization schedule in girls since 2008, and in 2017 it was extended to boys. However, vaccine coverage is decreasing nationwide. This study aims to examine anti-HPV vaccination practices in Health care services of Lazio Region, Italy. Questionnaires were sent or administered directly to those in charge of vaccinations. Data, collected from 11/12 (92%) Lazio Local Health Units and from 116 vaccination centers, show a remarkable diversity in the offer: 41% of the centers open only 1-2 days/week, 42% only in the morning, and only 7% are open on Saturday. Vaccination is available by reservation only in 62% of the centers, while vaccines are not administered to ≥18 years subjects in 33%; 93% of the centers call actively the girls in the target cohort, while 70% and 94% recall the patients who had not received the first or the second dose of vaccine, respectively. Collaboration with family physicians and/or pediatricians was declared by 80% of the centers. Vaccine coverage could probably be improved by addressing the highlighted critical issues and applying best practices widely.
