Abstract
BACKGROUND Influenza infection is a highly contagious viral disease. It may cause several nosocomial outbreaks. This study aimed to evaluate the knowledge and attitudes of healthcare workers (HCWs) about influenza vaccination and to identify factors associated with the uptake of influenza vaccination. METHODS We conducted a cross-sectional study over 5 months between November 2021 and March 2022. Data was collected using an anonymous self-administered questionnaire. We included all HCWs at Taher Sfar University Hospital who were willing to participate in the study. RESULTS A total of 395 HCWs were included. They were mainly women (78.7%) with an average age of 27 years. The medical personnel was the largest group (67.8%). Most respondents considered the vaccination to be optional and knew that it should be renewed every year, but 97.5% of them judged the efficacy of the vaccine to be low. The influenza vaccination uptake was only 20.2%. The main reasons for accepting vaccination were to protect patients and families. However, misconceptions about the severity and the risk of influenza and the belief that barrier measures were sufficient to prevent infection were the main causes of avoiding vaccination. The factors associated with adherence to vaccination were being a medical professional, old age, longer professional experience, and considering vaccination to be mandatory for HCWs. CONCLUSION Our study showed a low adherence to influenza vaccination with misconceptions about vaccine efficacy and safety. More efforts are needed to improve the knowledge of HCW about the vaccine and boost the adherence rates.

Abstract
Introduction Healthcare workers risk of exposure to the influenza virus in their work, is a high-risk group for flu infections. Thus WHO recommends prioritizing flu vaccination for them-an approach adopted by >40 countries and/or regions worldwide. Methods Cross-sectional studies on influenza vaccination rates among healthcare workers were collected from PubMed, EMBASE, CNKI, and CBM databases from inception to February 26, 2023. Influenza vaccination rates and relevant data for multiple logistic regression analysis, such as odds ratios (OR) and 95% confidence intervals (CI), were extracted. Results A total of 92 studies comprising 125 vaccination data points from 26 countries were included in the analysis. The meta-analysis revealed that the overall vaccination rate among healthcare workers was 41.7%. Further analysis indicated that the vaccination rate was 46.9% or 35.6% in low income or high income countries. Vaccination rates in the Americas, the Middle East, Oceania, Europe, Asia, and Africa were 67.1, 51.3, 48.7, 42.5, 28.5, and 6.5%, respectively. Influencing factors were age, length of service, education, department, occupation, awareness of the risk of influenza, and/or vaccines. Conclusion The global influenza vaccination rate among healthcare workers is low, and comprehensive measures are needed to promote influenza vaccination among this population.

Abstract
BACKGROUND The most cost-effective measure for preventing the infectious disease, influenza, is vaccination. The purpose of this research was to evaluate knowledge levels, familiarity, and attitude toward influenza and influenza vaccination of the Riyadh adult population. MATERIALS AND METHODS A cross-sectional study was carried out in Riyadh and data was collected between December 2017 and March 2018. Five hundred participants were interviewed in person using a closed-ended questionnaire. Participants comprised the general population, students, and healthcare workers (HCWs), and were recruited from shopping malls, parks, Princess Nourah Bint Abdulrahman University, and King Abdullah Bin Abdulaziz University Hospital. A pilot study was conducted among 15 participants from the general population, students, and HCWs who gave verbal consent. Participants were asked if they comprehended the questionnaire and whether they felt comfortable participating. Descriptive statistics were used to describe the sample. Statistical significance was determined using t-test for quantitative variables and Chi-square test for qualitative variables. RESULTS Most participants in all groups had poor knowledge. The least informed was the general population (8.8%), followed by the students (11.8%), and the most aware were the HCWs (18.5%). The social media (35%) was the main source of participants' knowledge, followed by doctors and health educators in hospitals (33%). Only 15.6% of participants had been vaccinated this year. Even fewer (8.8%) stated that they took the vaccination every year. The most important reasons for getting vaccinated were the recommendations by the Ministry of Health or by their doctors (77.8% for each). The key barrier to vaccination was a lack of perceived benefit (the participants did not usually get influenza so they felt vaccination was unnecessary [66.2%]). About 34% of participants reported that they had the children in their families vaccinated. The main reason given was to protect their children from influenza complications (80.6%). CONCLUSION Within the Riyadh adult population, there was both low compliance to take the influenza vaccinations owing to a lack of perceived benefit and insufficient knowledge of the risks of influenza.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19031586. [PMID: 35162609 PMCID: PMC8835710 DOI: 10.3390/ijerph19031586] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Revised: 01/25/2022] [Accepted: 01/28/2022] [Indexed: 01/29/2023]
Abstract
Background: Influenza vaccination, as a key element of control activities intended to prevent nosocomial influenza transmission, is recommended each year for all healthcare workers (HCWs). The objectives were to determine the rate of influenza vaccination and to identify reasons for receiving or declining the influenza vaccine among HCWs in the 2018/19 and 2019/20 influenza seasons. Methods: This study is a cross-sectional observational study carried out between January and March 2020, in 2 hospitals and 15 primary health-care settings (PHCS) in Wroclaw (Poland). Results: A total of 165 questionnaires were completed. The majority of participating HCWs were female—137 (83.0%), and, by profession, the majority were physicians 92 (55.8%). Influenza vaccination coverage was 61.2% in 2019/20, and 47.9% in the 2018/19 season for all participants. Participants who were male, physicians and personnel from PHCS were more frequently vaccinated in both seasons. According to the statistical analysis, physicians were more likely to receive vaccinations than nurses (p < 0.01), as were HCWs who had been vaccinated in the previous season (p < 0.001). Conclusion: The identified barriers were mainly caused by misconceptions (fear of vaccine adverse effects and perception of not being at risk/no need to get vaccinated) and an organizational barriers (lack of time). These findings may prove useful for designing immunization campaigns to tailor strategies to reach specific groups.

Abstract
Background Healthcare practitioners (HCPs) are at high risk of influenza. Seasonal influenza vaccines can reduce influenza-associated morbidity in healthcare settings, but despite mandatory influenza vaccination in the Kingdom of Saudi Arabia, the vaccination uptake rate among HCPs is below expectations. This study investigated vaccination trends from 2017 to 2020 to identify factors affecting vaccination among HCPs during the COVID-19 pandemic flu and subsequent seasons. Methods Cross-sectional study among HCPs was conducted in January 2021. A structured questionnaire was shared via social media. Vaccine uptake predictors were identified using descriptive statistics and logistic regression models (p-value 0.05). Results A total of 424 HCPs (118 physicians and 306 nurses) completed the questionnaire. Vaccine uptake increased from 2017 to 2019 (45% to 52% to 62%) but fell (to 59%) during the 2020 COVID-19 pandemic flu season. Multivariable analysis indicated participants >40 years old (AOR 3.09, 95% CI 1.64–5.83), female (AOR 1.74, 95% CI 1.13–2.67), non-Saudi (AOR 2.62, 95% CI 1.72–4.01), nurses (AOR 2.70, 95% CI 1.75–4.17), and who possessed accurate knowledge of the flu vaccine efficacy duration (AOR 3.04, 95% CI 1.87–4.94) were more likely to have received the vaccine. However, 79% of HCPs declared their intention to be vaccinated in the 2021 flu season, with participants >40 years old, female (AOR 2.25, 95% CI 1.38–3.68), non-Saudi (AOR 3.79, 95% CI 2.34–6.16), or nurses (AOR 2.94, 95% CI 1.82–4.76) more likely to do so. Conclusion Influenza vaccination uptake declined among HCPs during the 2020 flu season compared with the previous season but is expected to increase in the upcoming 2021 season. Nevertheless, the findings are encouraging and indicate increased willingness of HCPs to become vaccinated in the upcoming 2021 season, but coverage could be further increased by policymakers via a comprehensive plan focusing particularly on younger HCPs, Saudis, males, and physicians.

Influenza Vaccination Strategies in Healthcare Workers: A Cohort Study (2018-2021) in an Italian University Hospital. Vaccines (Basel) 2021; 9:vaccines9090971. [PMID: 34579208 PMCID: PMC8473239 DOI: 10.3390/vaccines9090971] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 08/17/2021] [Accepted: 08/27/2021] [Indexed: 11/17/2022] Open
Abstract
Vaccinating healthcare workers (HCWs) is the most effective intervention for preventing nosocomial influenza infection. However, influenza vaccination coverage (VC%) among HCWs remains low. The aim of the study was to analyse the trend of VC% among healthcare workers in an Italian hospital through a three-year vaccination project covering three influenza seasons (2018-2019, 2019-2020, and 2020-2021). A gap analysis was performed at the case base (2018-2019), on-site vaccination was trialled in the 2019-2020 season, and an integrated vaccination offer (on-site vaccination and the classic offer at a vaccination clinic) was implemented for the 2020-2021 season. For each unit of vaccinated HCWs, the following variables were recorded: main demographic details, area of affiliation (medical/surgical/services), and professional category. Logistic regression analyses were performed to assess the relationship between outcome (undergoing vaccination in 2020-2021) and other variables related to the healthcare workers' characteristics. In the three seasons, VC% values of 13.2%. 27.7%, and 58.9% were recorded, respectively (p < 0.005). The highest VC% was recorded among physicians (94.93%), in the medical area (63.27%), and males (62.59%) and in general among the youngest HCWs. Comparison of the coverage values recorded in the three seasons showed that in the last season considered (2020-2021) about 80% of health workers preferred to be vaccinated in the workplace instead of using the standard vaccination delivery method (invitation to attend the vaccination clinic). Our study suggests that the integrated vaccination offer may lead to an increase in VC% among HCWs compared to the classical offer modalities.

Abstract
Background The coverage for influenza vaccination among healthcare workers (HCWs) is inadequate in many countries despite strong recommendations; is there evidence that influenza vaccination is effective in preventing absenteeism? Aim of the study is to evaluate the influenza vaccination coverage and its effects on absences from work among HCWs of an Italian academic healthcare trust during the 2017–2018 influenza season. Methods We performed a retrospective study to identify predictive characteristics for vaccination, and a retrospective cohort study to establish the effect of vaccination on absences among the vaccinated and non-vaccinated cohorts between December 2017 and May 2018. Overall absence rates over the whole observation period and sub-rates over 14-days intervals were calculated; then comparison between the two groups were conducted applying Chi-square test. Results Influenza vaccination coverage among 4419 HCWs was 14.5%. Age, university degree, medical care area and physician profile were positively associated with vaccine uptake. Globally during influenza season non-vaccinated HCWs lost 2.47/100 person-days of work compared to 1.92/100 person-days of work among vaccinated HCWs (p < 0.001); significant differences in absences rates resulted when focusing on the influenza epidemic peak. Conclusions Factors predicting influenza uptake among HCWs were male sex, working within medical care area and being a physician. Absenteeism among HCWs resulted to be negatively correlated with vaccination against influenza. These findings add evidence to the urgent need to implement better influenza vaccination strategies towards HCWs to tackle vaccine hesitancy among professionals.

Abstract
Flu vaccination is recommended among healthcare workers (HCWs). The low vaccination coverage registered in our hospital among HCWs called for new engaging approaches to improve flu vaccination coverage. The aim of this study was to evaluate the efficacy of different strategies implemented during the last four years (2015-2019). A quasi-experimental study was conducted, involving almost 4000 HCWs each year. Starting from the 2015-2016 campaign, new evidence-based strategies were progressively implemented. At the end of each campaign, an evaluation of the vaccination coverage rate reached was performed. Moreover, during the last three campaigns, differences in coverage among job category, wards involved or not in on-site vaccination (OSV) intervention, age classes and gender were analyzed. An increasing flu vaccination coverage rate was registered, from 6% in 2015-2016 to almost 22% at the end of 2018-2019. The overall number of vaccinated HCWs increased, especially at younger ages. OSV strategy always leads to better results, and physicians always show a higher vaccination coverage than nurses and other HCWs. The implemented strategies were effective in achieving higher flu vaccination coverage among HCWs in our hospital and therefore can be considered valuable examples of good prevention practices in hospital settings.

Abstract
Flu vaccination, as well as being effective to prevent seasonal influenza, decreases staff illness and absenteeism and reduces costs resulting from loss of productivity. Despite the effectiveness of flu vaccination, the seasonal coverage among healthcare workers is usually low. The aim of this retrospective observational study was to analyze the vaccination coverage rate among all employees (healthcare workers and administrative staff) of a large teaching hospital in Rome during the 2017–2018 influenza season, to perform a cost-consequence analysis of influenza vaccination (by evaluating the absenteeism due to illness in the epidemic period), and to assess the impact of vaccination in terms of both costs and sick days. The flu vaccination coverage rate was 9.8% among 4631 healthcare workers and 852 administrative employees. The human capital approach estimated a loss of productivity equal to 297.06 € for each vaccinated worker and 517.22 € for each unvaccinated worker (cost-outcome ratio: 120.07 €/sick day). Applying the friction cost method, a loss of productivity equal to 237.65 € for each vaccinated worker and 413.78 € for each unvaccinated worker (cost-outcome ratio: 104.19 €/sick day) was found. These results confirm the benefits of the flu vaccination for the society and the company. This allowed the management to grant one hour of permission to the flu-vaccinated workers in the following annual vaccination campaign (2018–2019).

Abstract
Seasonal influenza vaccination (SIV) of health-care workers (HCWs) is recommended in most countries to protect them and their patients from infection. Although SIV can reduce the risk of influenza complications among vulnerable patients, vaccination uptake is generally unsatisfactory. The present study aimed to assess the impact of different programs in promoting SIV uptake among HCWs during the season 2017/2018 in four teaching hospitals in Rome. A multicentric cross-sectional study was carried out, in order to describe the four different campaigns and to assess their impact by identifying and developing a set of indicators that provide information about the vaccination services, the percentage of invited HCWs, the vaccinators' workforce and the vaccination coverage rates.The hospitals organized different strategies: Hospital 1, 3 and 4 organized educational courses for HCWs and actively invited every single HCW through e-mail. All the hospitals organized a dedicated unit for influenza vaccination, and Hospital 1 added on-site vaccination sessions that required a large number of staff. Hospital 1 and hospital 4 registered a comparable vaccination coverage rate, 12.97% and 12.76%, respectively, while it was 6.88% in Hospital 2 and 4.23% in Hospital 3. Our indicators demonstrated to be effective and useful for analyzing the different SIV campaigns. The results suggest that the best practice to promote SIV among HCWs should include multiple approaches. Among those, an easy access to the vaccination site seems to play a key role in determining a higher vaccination coverage.

Abstract
Background Vaccine coverage of health care professionals against influenza is still low in Italy, as well as in other European countries. Methods Between March and May 2018, this study was performed to collect the opinions of Pediatric health care professionals, working in emergency departments, regarding the efficacy and safety of the influenza vaccine. An anonymous online survey was employed to evaluate socio-demographic and professional characteristics, knowledges, beliefs and attitudes. Results Five hundred four health care professionals completed the survey: 331 physicians, 140 nurses and 33 other health are professionals. During the 2017–18 season, 55.8% of physicians, 19.3% of nurses and 12.1% of other health care professionals had vaccinated against the influenza virus. Not vaccinated physicians and nurses with less than 40 years of age were fewer than not vaccinated physicians and nurses with more than 40 years of age. Nurses and other health care professionals were less trustworthy of the influenza vaccination, less aware of the possibility of contracting and transmitting influenza and other vaccine-preventable diseases. Conclusions Insufficient adherence to the influenza vaccination in physicians, nurses and other health care professionals is a concern for those assisting high-risk patients, especially in emergency departments. Therefore, it is vital to promote education of health care professionals and students regarding vaccinations. High vaccine coverage should be embedded in the safe hospital paradigm and should become a goal for the hospital's directors.

Abstract
INTRODUCTION Vaccinations of healthcare workers (HCWs) aim to directly protect them from occupational acquisition of vaccine-preventable diseases (VPDs) and to indirectly protect their patients and the essential healthcare infrastructure. However, outbreaks due to VPDs continue to challenge healthcare facilities and HCWs are frequently traced as sources of VPDs to vulnerable patients. In addition, HCWs were disproportionately affected during the current measles outbreak in Europe. Areas covered: We reviewed the recent published information about HCWs vaccinations with a focus on mandatory vaccination policies. Expert commentary: Although many countries have vaccination programs specifically for HCWs, their vaccination coverage remains suboptimal and a significant proportion of them remains susceptible to VPDs. The increasing vaccination hesitancy among HCWs is of concern, given their role as trusted sources of information about vaccines. Mandatory vaccinations for HCWs are implemented for specific VPDs in few countries. Mandatory influenza vaccination of HCWs was introduced in the United States a decade ago with excellent results. Mandatory vaccinations for VPDs that may cause significant morbidity and mortality should be considered. Issues of mistrust and misconceptions about vaccinations should also be addressed.

Abstract
Despite relevant recommendations and evidences on the efficacy of influenza vaccination in health care workers (HCWs), vaccination coverage rates in Europe and Italy currently do not exceed 25%. Aim of the study is to measure the variations in vaccination coverage rates in an Italian pediatric hospital after a promotion campaign performed in the period October⁻December 2017. The design is a pre-post intervention study. The intervention is based on a wide communication campaign and an expanded offer of easy vaccination on site. The study was carried out at Bambino Gesù Children’s hospital in Rome, Italy, on the whole population of HCWs. Univariate and multivariate statistical analyses were performed. Vaccination coverage rate increased in 2017/18 campaign compared with the 2016/17 one (+95 HCWs vaccinated; +4.4%). The highest increases were detected in males (+45.7%), youngest employees (+142.9%), mean age of employment (+175%), other HCWs (+209.1%), Emergency Area (+151.6%) and Imaging Diagnostic Department (+200.0%). At multivariate logistic regression, working in some departments and being nurses represents a higher risk of being unvaccinated. Although the vaccination coverage rate remained low, a continuous increase of the coverage rate and development of a different consciousness in HCWs was highlighted. The study significantly identified the target for future campaigns.

Abstract
Influenza is a common disease and in children it can be severe enough to lead to hospitalization and death. Protection of all children against influenza, particularly the youngest, is strongly recommended by most health authorities. However, available vaccines cannot be used in the first 6 months of age, a period of life characterized by the highest risk of influenza-related complications. Maternal immunization is an attractive possibility to overcome this problem. For years, protection against influenza has been pursued by administering the trivalent inactivated vaccine given intramuscularly (IIV3). More recently, a trivalent live attenuated influenza vaccine (LAIV3) administered intranasally was licensed and adopted in a number of countries as an alternative to IIV3. In recent years, to increase protection and include a second B strain, quadrivalent inactivated (IIV4) and live attenuated vaccines (LAIV4) were prepared and licensed. However, during the 2015-2016 season the effectiveness of LAIVs was debated, and they were withdrawn from the list of recommended influenza vaccines in the USA. This review presents an update on the evidence related to the protection of infants against influenza through maternal immunization and the effectiveness of LAIV. Available data indicates that despite maternal immunization, a number of children have no protective antibody levels at birth, and in the majority of children with antibody protection, it is limited to the first 8 weeks of the postnatal period. Moreover, data on LAIV effectiveness in the pediatric population must be clarified because this vaccine can significantly improve vaccination coverage in children.

Abstract
Healthcare Workers (HCWs) have an increased risk both to acquire and to spread vaccine preventable diseases (VPDs) both to their colleagues and, especially, to vulnerable patients. The prevention of occupational hazards among HCWs is based on proper adoption of the standard and additional precautions, immunizations, and secondary preventive measures, such as post-exposure prophylaxis. Moreover, HCWs are often referred to as the most trusted source of vaccine-related information for their patients. In the present article, we report the findings of a cross-sectional study investigating the compliance to vaccinations among HCWs employed at the Obstetric Unit of a regional acute-care University Hospital in Northern Italy. Furthermore, a systematic review of the literature for some VPDs (i.e., HBV, measles, rubella, varicella and influenza) was performed, over a 17-year period, in order to update the socio-demographic and professional characteristics, the susceptibility status and the vaccination rates among HCWs in Italy.

Abstract
BACKGROUND Vaccination of health care workers (HCW) against seasonal influenza (SI) is recommended but vaccination rate rarely reach >30%. Vaccination coverage against 2009 pandemic influenza (PI) was 52% in our hospital, whilst a new policy requiring unvaccinated HCW to wear a mask during patient care duties was enforced. AIMS To investigate the determinants of this higher vaccination acceptance for PI and to look for an association with the new mask-wearing policy. METHODS A retrospective cohort study, involving HCW of three critical departments of a 1023-bed, tertiary-care university hospital in Switzerland. Self-reported 2009-10 SI and 2009 PI vaccination statuses, reasons and demographic data were collected through a literature-based questionnaire. Descriptive statistics, uni- and multivariate analyses were then performed. RESULTS There were 472 respondents with a response rate of 54%. Self-reported vaccination acceptance was 64% for PI and 53% for SI. PI vaccination acceptance was associated with being vaccinated against SI (OR 9.5; 95% CI 5.5-16.4), being a physician (OR 7.7; 95% CI 3.1-19.1) and feeling uncomfortable wearing a mask (OR 1.7; 95% CI 1.0-2.8). Main motives for refusing vaccination were: preference for wearing a surgical mask (80% for PI, not applicable for SI) and concerns about vaccine safety (64%, 50%) and efficacy (44%, 35%). CONCLUSIONS The new mask-wearing policy was a motivation for vaccination but also offered an alternative to non-compliant HCW. Concerns about vaccine safety and efficiency and self-interest of health care workers are still main determinants for influenza vaccination acceptance. Better incentives are needed to encourage vaccination amongst non-physician HCW.

Sustained low influenza vaccination in health care workers after H1N1 pandemic: a cross sectional study in an Italian health care setting for at-risk patients. BMC Infect Dis 2015; 15:329. [PMID: 26265328 PMCID: PMC4533948 DOI: 10.1186/s12879-015-1090-x] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2015] [Accepted: 08/05/2015] [Indexed: 11/10/2022] Open
Abstract
Background Despite consistent recommendations by all Public Health Authorities in support of annual influenza vaccination for at-risk categories, there is still a low uptake of influenza vaccine in these groups including health care workers (HCWs). Aim of this observational two-phase study was to estimate the immunization rates for influenza in four subsequent seasons and for pandemic H1N1 influenza in HCWs of a University Hospital, and to investigate its distribution pattern and the main determinants of immunization. Phase 1 data collection was performed in 2009–2010, during the peak of H1N1 pandemic. Phase 2 data collection, aimed to investigate seasonal influenza vaccination coverage in the three seasons after pandemic, was performed in 2012–2013. Methods The overall H1N1 vaccination rate was derived by the Hospital immunization registry. In 2010, the personnel of three Departments (Infectious Diseases, Pediatrics and Gynecology/Obstetrics) completed a survey on influenza. A second-phase analysis was performed in 2012 to investigate influenza vaccination coverage in three consecutive seasons. Results The first-phase survey showed a low coverage for influenza in all categories (17 %), with the lowest rate in nurses (8.1 %). A total of 37 % of health care workers received H1N1 vaccine, with the highest rate among physicians and the lowest in nurses. H1N1 vaccination was closely related to the Department, being higher in the Department of Infectious Diseases (53.7 %) and Pediatrics (42.4 %) than in Gynecology/Obstetrics (8.3 %). The second-phase survey showed the lowest rate of influenza vaccination in 2012/13 season. The main reasons for not being vaccinated were “Unsure of the efficacy of vaccine” and “Feel not at-risk of getting influenza or its complications”. Despite recommendations, influenza vaccine uptake remains poor. Conclusion Immunization is largely perceived as a personal protection rather than a measure needed to prevent disease spreading to at-risk patients. Compulsory vaccination against influenza should be considered as a possible strategy, at least in health institutions where at-risk patients are admitted.

Abstract
BACKGROUND The aims of this study were: a) to evaluate attitudes and practices of health care workers (HCWs) towards influenza vaccination and their opinion regarding a vaccination promotion toolkit; b) to estimate hospital HCWs' influenza vaccination coverage rates (VC). METHODS The Bambino Gesù Children's Hospital (OPBG) is an academic hospital in Italy. Since 2009, free influenza vaccination is offered to HCWs during working hours. In October-December 2013, a communication campaign based on a standardized toolkit was conducted. In December 2013, we performed a cross-sectional survey in a sample of hospital wards, based on a self-administered questionnaire including participants' characteristics; self-reported influenza vaccination history; reasons for vaccination or missed vaccination; opinion regarding the toolkit. Multivariable logistic analysis was used to assess independent predictors of influenza vaccination status. Annual VC for years 2009-2013 was estimated by using the number of seasonal influenza vaccine doses administered to HCWs as numerator, and the number of hospital HCWs as denominator. RESULTS Out of 191 HCWs who participated in the survey, 35.6% reported at least one influenza vaccination during their life; 6.8% adhered to annual revaccination. Years of service and professional category were significantly and independently associated with vaccination (adjusted-OR: 2.4 for > 10 years of service, compared to < 5 years of service; adjusted-OR: 2.6 for physicians compared to nurses). Patient protection was the main reported reason for vaccination (34.3%); considering influenza a mild disease was the main reason for non-vaccination (36.9%); poor vaccine effectiveness was the main reason for missed annual revaccination (28.8%). Overall, 75% of respondents saw at least one promotion tool; 65.6% of them found the information useful. Hospital VC decreased from 30% in 2009, to 5% in 2012. In 2013, VC was 14%. CONCLUSIONS Satisfactory influenza VC in HCWs is hard to achieve. In 2013, along with the toolkit implementation, we observed an increase in HCWs' vaccination coverage, nevertheless, it remained unsatisfactory. Tailored information strategies targeting nurses and recently employed HCWs should be implemented. Institution of declination statements, adding influenza vaccination to financial incentive systems, or vaccination requirements should also be considered to increase influenza VC among HCWs.

Abstract
Primary healthcare workers, especially nurses, are exposed to the vast majority of patients with influenza and play an important role in vaccinating patients. Healthcare workers’ misconceptions about influenza and influenza vaccination have been reported as possible factors associated with lack of vaccination. The objective of this study was to compare the characteristics of unvaccinated physicians and unvaccinated nurses in the 2011–2012 influenza season. We performed an anonymous web survey of Spanish primary healthcare workers in 2012. Information was collected on vaccination and knowledge of and attitudes to the influenza vaccine. Multivariate analysis was performed using unconditional logistic regression. We included 461 unvaccinated physicians and 402 unvaccinated nurses. Compared with unvaccinated nurses, unvaccinated physicians had more frequently received seasonal influenza vaccination in the preceding seasons (aOR 1.58; 95% CI 1.11–2.25), and more frequently believed that vaccination of high risk individuals is effective in reducing complications (aOR 2.53; 95% CI 1.30–4.95) and that influenza can be a serious illness (aOR 1.65; 95% CI 1.17–2.32). In contrast, unvaccinated physicians were less concerned about infecting patients (aOR 0.62; 95% CI 0.40–0.96). Unvaccinated nurses had more misconceptions than physicians about influenza and the influenza vaccine and more doubts about the severity of annual influenza epidemics in patients with high risk conditions and the prevention of complications by means of the influenza vaccination. For unvaccinated physicians, strategies to improve vaccination coverage should stress the importance of physicians as a possible source of infection of their patients. The effectiveness of influenza vaccination of high risk persons should be emphasized in nurses.

Participantes Se incluyó a 1.212 profesionales de atención primaria. Se excluyó a los profesionales con contraindicación para recibir la vacuna o indicación de vacunación por condición médica de riesgo y aquellos que hubieran participado en la red centinela de vigilancia de la gripe Pla d’Informació Diària d’Infeccions Respiratòries Agudes de Catalunya (PIDIRAC). Resultados Se consideraron 423 respuestas válidas, con una cobertura vacunal global del 46,6%. Se vacunaron más los que tenían de 45 a 54 años, los pediatras, los vacunados en las 3 temporadas anteriores o en alguna de ellas y los que convivían con enfermos crónicos. Se observó asociación entre estar vacunado y considerar que la vacunación es la mejor medida preventiva, preocupación por contraer la gripe y considerar importante la vacunación del personal sanitario. Conclusiones Las actividades dirigidas a aumentar la cobertura de vacunación en profesionales sanitarios deberían dirigirse fundamentalmente a corregir concepciones erróneas sobre la vacunación de la gripe en profesionales sanitarios.

Abstract
Background To assess the contribution of physician-related factors, especially their influenza vaccine status, in the vaccination coverage of their patients. Methods A study of vaccination coverage was carried out in Spain in 2011–12. The dependent variable (vaccination coverage in patients aged ≥65 years) was obtained from regional records. Information was gathered on the vaccination of physicians through an anonymous web survey. We compared the vaccination coverage of patients with the vaccination of their physicians using the Student t test. Associations were determined using a multilevel regression model. Results The coverage in patients aged ≥ 65 years was 56.3% and was higher (57.3%) in patients whose physician had been vaccinated than in those whose physician had not (55.2%) (p = 0.008). In the multilevel regression model, vaccination of the physician was associated (p = 0.049) with vaccination of their patients after controlling for the effects of age (p = 0.046), region (p = 0.089), and opinions on the effectiveness of the vaccine (p = 0.013). Conclusions Vaccination of physicians together with their opinions on the effectiveness of the vaccine may be a predictor of vaccination coverage in their patients. Further studies are required to confirm this.

Abstract
PURPOSE To characterize groups of primary healthcare physicians according to sociodemographic data, years of professional experience and knowledge of and attitudes to influenza, and to evaluate differences between groups with respect to influenza vaccination in the 2011-2012 season. METHODS We carried out an anonymous web survey of Spanish primary healthcare physicians in 2012. Information on vaccination, and knowledge of and attitudes to influenza was collected. Multiple correspondence analysis and cluster analysis were used to define groups of physicians. RESULTS We included 835 physicians and identified three types. Type B were physicians with low professional experience of influenza. Types A and C were physicians with high professional experience with influenza, type A also had a high awareness of influenza and seasonal vaccination. Types A and C were older and more often male than type B (p<0.0001). Knowledge of influenza was greatest in type A and lowest in type B. Awareness of influenza was greatest in type A and lowest in type C. In type A, 71.0% of physicians were vaccinated in the 2011-2012 season, compared with 48.1% and 33.6% from types B and C, respectively (p<0.001). CONCLUSIONS Additional efforts should be made to increase interest and concerns about preventing the transmission of influenza in physicians who do not believe influenza is a severe disease and are not concerned about its transmission.

Abstract
We analyzed seasonal influenza vaccination coverage among the Italian healthcare workers (HCW) in order to identify socio-demographic and clinical determinants of vaccination. We used data from the survey "Health and health care use in Italy," which comprised interviews of 5,336 HCWs For each respondent, information on socioeconomic, health conditions, self-perceived health and smoking status were obtained. After bivariate analysis, we used multilevel regression models to assess determinants of immunization. Overall 20.8% of HCWs (95%CI 19.7-21.9) reported being vaccinated against seasonal influenza. After controlling for potential confounders, multilevel regression revealed that older workers have a higher likelihood of vaccine uptake (OR = 6.07; 95% CI 4.72-7.79). Conversely, higher education was associated with lower vaccine uptake (OR = 0.65; 95% IC 0.50-0.83). Those suffering from diabetes (OR = 2.07; 95% CI 1.19-1.69), COPD (OR = 1.95; 95% CI 1.31-2.89) and cardiovascular diseases (OR = 1.48 95% CI 1.11-1.96) were more likely to be vaccinated. Likewise, smokers, or former smokers receive more frequently the vaccination (OR = 1.40; 95% CI 1.15-1.70; OR = 1.54; 95% CI 1.24-1.91, respectively) compared with never-smokers as well as those HCWs reporting fair or poor perceived health status (ORs of 1.68, 95% CI 1.30-2.18). Vaccine coverage among HCWs in Italy remains low, especially among those with no comorbidities and being younger than 44 y old. This behavior not only raises questions regarding healthcare organization, infection control in healthcare settings and clinical costs, but also brings up ethical issues concerning physicians who seem not to be very concerned about the impact of the flu on themselves, as well as on their patients. Influenza vaccination campaigns will only be effective if HCWs understand their role in influenza transmission and prevention, and realize the importance of vaccination as a preventive measure.

Abstract
Annual influenza vaccination is recommended for healthcare workers, but many do not follow the recommendation. The objective of this study was to investigate the factors associated with seasonal influenza vaccination in the 2011–2012 season. We carried out an anonymous web survey of Spanish primary healthcare workers in 2012. Information on vaccination, and knowledge and attitudes about the influenza vaccine was collected. Workers with medical conditions that contraindicated vaccination and those with high risk conditions were excluded. Multivariate analysis was performed using unconditional logistic regression. We included 1,749 workers. The overall vaccination coverage was 50.7% and was higher in workers aged ≥ 55 years (55.7%), males (57.4%) and paediatricians (63.1%). Factors associated with vaccination were concern about infection at work (aOR 4.93; 95% CI 3.72–6.53), considering that vaccination of heathcare workers is important (aOR 2.62; 95%CI 1.83–3.75) and that vaccination is effective in preventing influenza and its complications (aOR 2.40; 95% CI 1.56–3.67). No association was found between vaccination and knowledge of influenza or the vaccine characteristics. Educational programs should aim to remove the misconceptions and attitudes that limit compliance with recommendations about influenza vaccination in primary healthcare workers rather than only increasing knowledge about influenza and the characteristics of the vaccine.

Abstract
Background The objectives of the survey were to identify the level of influenza vaccination coverage in China in three influenza seasons 2009/10 to 2011/12, and to find out potential predictors for seasonal influenza vaccination. Methods In September and October 2011, representative urban household telephone surveys were conducted in five provinces in China with a response rate of 6%. Four target groups were defined for analysis: 1) children ≤5 years old; 2) elderly persons aged ≥60 years old; 3) health care workers (persons working in the medical field) and 4) chronically ill persons. Results The overall mean vaccination rate was 9.0%. Among the four target groups, the rate of vaccination of children aged ≤5 years old (mean = 26%) was highest and the rate of elderly people aged ≥60 years old (mean = 7.4%) was the lowest, while the rates of persons who suffer from a chronic illness (mean = 9.4%) and health care workers (9.5%) were similar. A subsidy for influenza vaccination, age group, health care workers, suffering from a chronic illness and living in Eastern China were independent significant predictors for influenza vaccination. Conclusions The seasonal influenza vaccination coverage rates among urban populations in selected cities and provinces in China were far below previously reported rates in developed countries. Influenza vaccination coverage rates differed widely between different target groups and provinces in China. Subsidy policy might have a positive effect on influenza vaccination rate, but further cost-effectiveness studies, as well as the vaccination rate associated factors studies are still needed to inform strategies to increase coverage.

Abstract
BACKGROUND To improve influenza vaccination coverage in the working age population, it is necessary to understand the current status and awareness of influenza vaccination. This study aimed to determine influenza vaccination coverage in Japan and reasons for receiving the vaccine or not. METHODS An anonymous internet-based survey was performed in September 2011. Our target study size was 3,000 participants between 20 and 69 years of age, with approximately 300 men and 300 women in each of five age groups (20-29, 30-39, 40-49, 50-59, and 60-69). We asked the history of influenza vaccine uptake in the previous year, and reasons for having vaccination or not. RESULTS There were 3,129 respondents, of whom 24.2% of males and 27.6% of females received influenza vaccination between October 2010 and March 2011. Among those who were vaccinated, the main reasons for receiving the influenza vaccine were "Wanted to avoid becoming infected with influenza virus" (males: 84.0%; females: 82.6%) and "Even if infected with influenza, wanted to prevent the symptoms from becoming serious" (males: 60.7%; females: 66.4%). Among those not vaccinated, the most frequent reasons for not receiving the influenza vaccine included "No time to visit a medical institution" (males: 32.0%; females: 22.4%) and "Unlikely to become infected with influenza" (males: 25.1%; females: 22.7%). CONCLUSIONS The reasons for receiving the influenza vaccine varied between age groups and between sexes. To heighten awareness of influenza vaccination among unvaccinated working age participants, different intervention approaches according to sex and age group may be necessary.

Abstract
BACKGROUND Health care workers' (HCW) compliance with infection control measures is influenced by organizational, environmental and individual factors. However, it is unknown whether HCWs' perceptions of transmission risk and protectiveness of infection control measures influences the uptake of infection control measures. METHODS A questionnaire of perceptions and intentions to use infection control measures was completed by 74 HCWs at 2 hospitals. HCWs also indicated a 1-m transmission risk zone and their perceived transmission risk zone. Responses were used in logistic regression models to predict intended behaviors. RESULTS Poor recognition of the importance of employing a 1-m transmission risk zone predicted intention not to don a mask in single rooms where patient contact was unexpected (adjusted odds ratio [AOR], 0.5; P = .032). When contact was expected, perceived protectiveness of pre-exposure prophylaxis (AOR, 7.9; P < .001), vaccination (AOR, 3.6; P = .023), and a minimum 1-m risk zone (AOR, 9.8; P = .022) predicted mask use. HCWs perceived transmission risk zones within 2.45 m from attending an adult and 1.12 m from attending pediatric patients. CONCLUSION Intention to use a facemask was poor for care in single rooms but improved if patient contact was expected and in multibed rooms. HCWs attending pediatric patients measured a smaller transmission risk zone than what is currently recommended under droplet precautions.

Abstract
BACKGROUND In Australia, whether to provide free influenza vaccine to health care workers (HCWs) is a policy decision for each hospital or jurisdiction, and is therefore not uniform across the country. This study explored hospital policies and practices regarding occupational influenza vaccination of HCWs in Australia. METHODS A study using qualitative methodology, which included semi-structured interviews, was undertaken with hospital staff involved with the delivery of occupational influenza vaccination from three states in Australia. RESULTS The 29 participants were responsible for vaccinating staff in 82 hospitals. Major themes in the responses were the lack of resources and the difficulties participants faced in procuring any additional support or funding from their institutions. All study sites provided vaccine free of charge to employees via on-site clinics or mobile carts, and used multiple strategies to inform and educate their staff. In some instances, declination forms had been adopted, however their use was associated with resourcing issues, animosity, and other problems. Participants who were responsible for multiple sites were more likely to recount lower vaccination coverage figures at their hospitals. CONCLUSIONS From these interviews, it is clear that hospitals are implementing multiple strategies to educate, promote, and deliver the vaccine to staff. However, resources and support are not always available to assist with the vaccination campaign. The reality for many hospitals is that there is limited capacity to implement the vaccination campaigns at the levels high enough to raise compliance rates. Further research needs to be conducted to quantify the factors contributing to higher uptake in the Australian hospital setting.

Abstract
BACKGROUND Vaccination is an important preventive measure for preparing against the influenza pandemics. This study investigated the attitudes and perceptions of influenza vaccination among doctors and medical students in Hong Kong. METHODS A cross-sectional survey was conducted among 204 doctors and 242 medical students in a teaching hospital in 2009. Participants' demographic and job characteristics, and influenza experience and vaccination in the previous year were assessed in the questionnaire. Logistic regression models were used to examine the associations between uptake of influenza vaccination and the perceived benefits. RESULTS Medical students were more likely to have receive an influenza vaccination in the previous year (66.9 vs. 39.7%) and acknowledged the related benefits than doctors. Moreover, uptake of influenza vaccine was associated with perceived benefits of vaccination in both doctors and medical students. CONCLUSIONS The perceived benefits of influenza vaccination are an important factor in vaccine uptake for both doctors and medical students in Hong Kong, and should be reinforced in the professional training.

Abstract
OBJECTIVE To determine the intention of health professionals, doctors and nurses, concerning whether or not to be vaccinated against A/H1N1 influenza virus, and their perception of the severity of this pandemic compared with seasonal flu. MATERIAL AND METHODS A cross-sectional study was carried out based on an questionnaire e-mailed to health professionals in public healthcare centres in Vitoria between 6 and 16 November 2009; the percentage of respondents who wanted to be vaccinated and who perceived the pandemic flu to carry a high risk of death were calculated. RESULTS A total of 115 people completed the questionnaire of whom 61.7% (n=71) were doctors and 38.3% (n=44) were nurses. Of these, 33.3% (n=23) of doctors and 13.6% (n=6) of nurses intended to be vaccinated (p=0.019). Even among those who considered themselves to be at a high risk, 70.6% (n=48) of doctors and 31.7% (n=13) of nurses participating in the study (p=0.001) planned to have the vaccination. CONCLUSIONS Most health professionals, and in particular nurses, had no intention to be vaccinated against A/H1N1 influenza virus at the beginning of the vaccination campaign.

Abstract
Based on an increasingly extensive literature expressing the large interest in the field, this paper gives an overview of different aspects of influenza prevention in children. It relies on paradoxes. First, the heaviest part of the burden is well demonstrated in the youngest infants by numerous epidemiological data elsewhere. On the contrary, with older children, the prevention by influenza vaccines is more efficacious-without notable side effects. Second, the available TIV vaccines are 60 years old and the requests of registration and regulation of vaccines have evolved. There is a specific need in children: it is time to re-discuss the pragmatic utilization of influenza vaccines (full dose in the youngest patient? More flexibility regarding the interval between the two required doses in vaccine-naïve children), and to change from a compassionate use to a targeted research and adapted vaccines considering the limits of TIV in the youngest children. Third, influenza virus transmission is the highest in children in semi-close communities (day-care centers, schools), diffusing to households and more largely to the population. A restricted policy on high risk groups (roughly 10% in a pediatric population, all medical conditions including asthma, for whom influenza vaccine coverage is a 15-75% range) is far below the estimated threshold of 45% coverage rate to limit the virus circulation by an indirect impact during seasonal epidemics. Fourth, public health decisions in the vaccination field are usually taken from top to bottom. The pandemic A/H1N1 has toughly demonstrated that "forgetting" about the perception and expectations of the public and the parents nearly created conflicts and at least a strong resistance impeding the quality of a program worked on for a long time ahead. Fifth, and not the least, HCPs are pivotal in influenza vaccination mostly trusted by the parents. Too often, they are not backed by a national and clear support and they need to reinforce their knowledge on the disease and the vaccines.

Abstract
Introduction A novel H1N1 vaccine was manufactured in response to the pandemic in 2009. This study describes the willingness to be vaccinated for H1N1 among healthcare workers (HCWs) in primary healthcare clinics with and without chronic medical conditions, their reasons for refusing vaccination and whether they sought additional information to make an informed decision for the vaccination. Materials and methods An anonymous survey was conducted in November 2009 among all medical, nursing, allied health and operations HCWs in nine primary care clinics in Singapore. Participants were asked if they had any chronic medical conditions associated with influenza-related complications (example: asthma, stroke, heart disease, cancer, diabetes mellitus, renal disease), their perception towards vaccination for H1N1 and against seasonal influenza within the preceding 2 years. Results The initial response rate was 80%, of which 711 (54.7%) of the completed surveys were analysed. Among the 711 respondents, 16.6% reported having at least 1 chronic disease. Asthma (10.8%), hypertension (10.4%) and dyslipidaemia (9.8%) were the main chronic conditions. Only 39.4% of respondents were willing to be vaccinated against H1N1. Males were 2.07 (95% CI 1.19–3.62) times more likely than females to receive the H1N1 vaccination; the 45–54 and 55+ years old were 2.12 (95% CI 1.06–4.24) and 2.44 (95% CI 1.13–5.27) times more willing than those below 25 years old; and those who considered accepting the seasonal influenza vaccine were 7.0 times more likely than those who did not (95%CI 4.48–10.92). The 2 principal barriers were “fear of side effects” and “unsure of vaccine's effectiveness”. Although 78% attended some H1N1-related talks, only 7% of all HCWs felt that they had sufficient information. Most wanted more information about the vaccine's safety profile and contraindications. Conclusion Fewer than 40% of HCWs expressed willingness to receive the H1N1 vaccination, lower than past rates of influenza vaccine. HCWs in primary care clinics who had a chronic condition did not perceive themselves to be at higher risk of developing H1N1-related complications and were not more willing than the rest of the HCWs to accept H1N1 vaccination. Vaccine's side effects and effectiveness were the main concerns. Uptake of H1N1 vaccine may improve with targeted health information covering the vaccine's safety profile.

Abstract
In 2008/2009 a nationwide cross-sectional telephone survey was conducted to assess, among other health-relevant parameters, seasonal influenza vaccination coverage. Data from 21,262 household-interviews representative of the adult population in Germany were collected and analyzed. In seasons 2007/2008 and 2008/2009, vaccine uptake in individuals aged ≥60 years was 57% and 55% and in individuals with underlying chronic diseases 44% and 42%. Living in the eastern part of Germany, higher age, and medium household income level were independently associated with higher vaccine uptake in both target groups. Healthcare workers were significantly less frequently (21.9% in 2007/2008; 20.4% in 2008/2009) vaccinated than the general population (30.8% and 28.1%). Special effort must be undertaken to develop immunization strategies for improved vaccine uptake in target groups, especially in healthcare workers.

Abstract
Background The H1N1 influenza pandemic had garnered a large amount of attention. Currently, the most effective preventive measure available is the H1N1 vaccine. We aimed to assess the willingness of our study participants to receive the H1N1 vaccination prior to the annual Hajj season. If any participant declined, we investigated the reasons for vaccine rejection. Findings We conducted a prospective cohort study of National Guard employees during the 1430 (2009) Hajj season. A survey was used as the primary method for data collection. Participants were vaccinated one to two weeks prior to their trip to Mona, and any side effects reported at the time of injection and three weeks post vaccination were recorded. There were 100 male and 26 female participants in the study. In total, 66.7% (n = 84) of the participants were health care workers (HCWs) and 33.3% (n = 42) were non-health care workers (non-HCWs). Less than half of the respondents (46.8%, n = 59) accepted the vaccination. The vaccination acceptance rate was higher among non-HCWs, at a rate of 71.4% (n = 30); HCWs only accepted at a rate of 34.5% (n = 29) (OR 1.103, 95% CI [0.488-2.496]). The most common reason for vaccine refusal was the impression that the disease was not fatal (25.4%, n = 32). Finally, all participants reported pain at the injection site and 18.3% (n = 11) reported swelling. All other side effects were reported in less than 15% of the participants. Conclusions Despite fears of the new H1N1 vaccine, there was a reasonable rate of vaccine acceptance among our study participants. Early health education may increase the rate of acceptance of the H1N1 vaccine. Furthermore, additional research is needed on long-term adverse effects of the H1N1 vaccine.

Abstract
OBJECTIVE To assess healthcare workers' attitudes and concerns regarding seasonal and pandemic influenza vaccines in order to improve vaccination campaign communications. DESIGN Cross-sectional survey. SETTING All 6 health authorities in British Columbia, Canada. METHODS An anonymous, self-administered online survey was conducted from August 30 through September 30, 2009. Question topics included demographic characteristics, factors influencing acceptance of seasonal influenza vaccine, factors influencing intentions to accept pandemic H1N1 influenza vaccine, and knowledge and concerns regarding the effect of the influenza pandemic. PARTICIPANTS All 96,217 British Columbia healthcare workers were eligible to participate. RESULTS A volunteer sample of 4,046 healthcare workers returned the survey; 3,563 (88%) were women, 58% were under 50 years old (mean age + or - standard deviation, 45.3 + or - 10.9 years), 3,152 of 4,023 (79%) had 5 or more years of experience in their profession, 1,853 of 4,023 (46%) were nurses, and 2,833 (70%) had been vaccinated against seasonal influenza the previous year. Two thousand eight hundred (69%) respondents reported intending to receive the pandemic H1N1 vaccine. The most important predictor of this intention was having received the seasonal vaccine the previous year (odds ratio [OR], 6.25 [95% confidence interval {CI}, 5.39-7.26]). Worry about making loved ones ill was the only attitude associated with intention to receive the pandemic H1N1 vaccine (adjusted OR, 1.38 [95% CI, 1.27-1.50]). Concerns with vaccine safety (adjusted OR, 0.31 [95% CI, 0.25-0.39]) and belief "that H1N1 is not severe enough" (adjusted OR, 0.29 [95% CI, 0.26-0.32]) were independently associated with the intention to reject the pandemic H1N1 vaccine. CONCLUSIONS Vaccination campaigns for pandemic H1N1 vaccine should use messages that emphasize the risk of illness among younger people and the opportunity to protect loved ones by getting the vaccine and should address concerns about the safety and effectiveness of the vaccine.

Abstract
The aim of the study was to investigate factors involved in vaccination acceptance among healthcare workers (HCWs) and adverse reactions rates associated with pandemic influenza vaccination. The study was carried out in the major teaching hospital of Sicily from November 2009 to February 2010 on 2267 HCWs. A total of 407 (18%) HCWs were vaccinated against the 2009 pandemic influenza A (H1N1). A logistic regression analysis indicates an increased risk of non-vaccination against pandemic influenza in females (OR=1.6; 95% CI=1.3-2.1) compared to males, in nurses/technicians/administrative workers (OR=1.7; 95% CI=1.3-2.2) compared to doctors/biologists, and in HCWs who were non-vaccinated against seasonal influenza in 2008-2009 (OR=4.9; 95% CI=3.7-6.5) compared to vaccinated HCWs. Overall, 302 (74.2%) out of 407 questionnaires distributed to vaccinated HCWs were returned within the observation period. One hundred fifty-two workers (50.3%) experienced at least one adverse reaction (30.1%, local reactions; 6.6% systemic reactions and 13.6% both of them). The most frequent side effect of vaccination was pain at the injection site (43.4%). Twelve (3.9%) out of 302 HCWs stated they experienced influenza-like illness episodes during the follow-up period. The use of an adjuvanted vaccine against pandemic influenza A (H1N1) appears to be an effective and safe preventive strategy, showing a prevalence of both local and systemic adverse reactions not very different from that seen after vaccination with non-adjuvanted seasonal influenza vaccine. Despite this finding, vaccination coverage among HCWs remains very low, suggesting the need to implement educational campaigns directed to groups with lower coverage rates.

Abstract
PURPOSE OF REVIEW This review discusses why influenza should be considered an important clinical problem even in healthy children, and what can be expected from the use of influenza vaccines in pediatrics. RECENT FINDINGS It has been demonstrated that not only children with an underlying disease but also otherwise healthy children can suffer from severe influenza. The greatest clinical problems arise during the first 23 months of life, but a substantial number of children aged 2-5 years and more than 5 years can die or be hospitalized. This suggests that adequate prophylactic measures should be planned for all children, regardless of their age. An influenza vaccination can be administered using a trivalent inactivated influenza virus or live attenuated influenza virus vaccine, and in both cases seems to be highly cost-effective. However, the actual use of influenza vaccines in children continues to be less than officially recommended. SUMMARY Influenza is a clinical problem for children at risk because of underlying disease and previously healthy children. Effective vaccines are currently available, and their extensive pediatric use seems to be associated with significant clinical and socioeconomic advantages.

Abstract
The clinical and economic burden of seasonal influenza is frequently underestimated. The cornerstone of controlling and preventing influenza is vaccination. National and international guidelines aim to implement immunization programs and targeted vaccination-coverage rates, which should help to enhance the vaccine uptake, especially in the at-risk population. This review purposes to highlight the vaccination guidelines and the actual vaccination situation in four target groups (the elderly, people with underlying chronic conditions, healthcare workers and children) from a European point of view.
