Peng Y, Wang Y, Huang W, Lin J, Zeng Q, Chen Y, Qiao F. Exploring Perceptions and Barriers: A Health Belief Model-Based Analysis of Seasonal Influenza Vaccination among High-Risk Healthcare Workers in China. Vaccines (Basel) 2024; 12:796. [PMID: 39066434 PMCID: PMC11281488 DOI: 10.3390/vaccines12070796] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2024] [Revised: 07/12/2024] [Accepted: 07/16/2024] [Indexed: 07/28/2024] Open
Abstract
The annual seasonal influenza vaccination rate among high-risk healthcare workers (HCWs) has fallen below expectations, underscoring the importance of exploring the impact of perception on vaccination behavior. An online survey, grounded in the Health Belief Model (HBM), was administered to high-risk healthcare workers at West China Hospital. The data analysis encompassed descriptive statistics, logistic regression for univariate analysis, and path regression for multivariate analysis. A total of 1845 healthcare workers completed the survey, with an acceptance rate of 83.90% (95% CI, 82.20-85.60%). Path analysis revealed significant correlations between vaccination acceptance and perceived susceptibility (β = 0.142), perceived benefits (β = 0.129), perceived barriers (β = 0.075), exposure to vaccination advertisements (β = 0.115), and knowledge about seasonal influenza (β = 0.051). Vaccination education efforts should prioritize elucidating the risks associated with the disease and emphasizing the benefits of vaccination. Furthermore, leveraging advertising proves to be an effective strategy for promotion.

Co-administration of SARS-CoV-2 and influenza vaccines in healthcare workers: Results of two vaccination campaigns in a large teaching hospital in Rome. Hum Vaccin Immunother 2023; 19:2287282. [PMID: 38016914 PMCID: PMC10732597 DOI: 10.1080/21645515.2023.2287282] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2023] [Accepted: 11/20/2023] [Indexed: 11/30/2023] Open
Abstract
The concurrent administration of COVID-19 and influenza vaccines has arisen as a promising approach to bolster protection against respiratory pathogens and improve vaccination rates. However, there remains a lack of data regarding the prevalence of co-administration across several vaccination campaigns, especially among healthcare workers (HCWs). Therefore, this study aims to shed light on the acceptance of co-administration strategies among HCWs during the two campaigns following the introduction of the anti-SARS-CoV-2 vaccine. A retrospective cohort study was conducted among the HCWs of the Fondazione Policlinico Universitario "A. Gemelli" IRCCS, a research hospital in Rome. Hospital administrative databases were accessed to gather information about vaccination for SARS-CoV-2 and influenza during the 2021/2022 and 2022/2023 vaccination campaigns. The study included 7399 HCWs. The co-administration of anti-SARS-CoV-2 and influenza vaccines presented a significant rise in 2022/2023 compared to the previous vaccination campaign (+38%): this was confirmed for every professional category, with the largest increases among resident doctors (+47%) and physicians (+44%), and also for every age category, but it was particularly evident for the youngest health professionals. The probability of co-administration uptake during the 2022/2023 campaign was significantly higher for males, and for those that received co-administration during the 2021/2022 campaign, while the probability was lower for nurses and administrative staff. This study highlights the co-administration procedure as a valuable and effective tool in annual vaccination campaigns for SARS-CoV-2 and influenza. The procedure's safety and streamlined logistics make it increasingly attractive for implementation, particularly among HCWs.

[PMID: 36560468 PMCID: PMC9783052 DOI: 10.3390/vaccines10122058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 11/28/2022] [Accepted: 11/29/2022] [Indexed: 12/04/2022] Open
Abstract
Healthcare workers (HCWs) are at increased risk of SARS-CoV-2 infection because of their occupational exposure. Moreover, they can be a vehicle for the virus transmission among patients. The vaccination of healthcare personnel against COVID-19 is crucial in fighting the spread of SARS-CoV-2 infection, together with strict sanitary procedures that aim to limit the risk of contagion. Unfortunately, even if COVID-19 vaccination has been proved one of the most effective tools for protecting against COVID-19, many healthcare professionals are not yet vaccinated. The aim of the current review is to contribute to identifying an effective strategy for COVID-19 prevention especially among non-vaccinated HCWs. In this review, we collected the most recent and relevant findings from literature on the protection of unvaccinated HCWs, identifying three types of measures as principal actions to protect those operators: addressing vaccine hesitancy, improving non-pharmaceutical interventions and promoting actions at personal level (respiratory hygiene, hand hygiene and use of PPE). All these interventions are very effective in preventing contagion, if well respected and conducted; nevertheless, it is essential to promote vaccination, as it is the most effective measure.

Flu and COVID-19 Vaccination: What Happens to the Flu Shot When the Campaigns Overlap? Experience from a Large Italian Research Hospital. Vaccines (Basel) 2022; 10:vaccines10060976. [PMID: 35746583 PMCID: PMC9228127 DOI: 10.3390/vaccines10060976] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Revised: 06/16/2022] [Accepted: 06/17/2022] [Indexed: 12/14/2022] Open
Abstract
Influenza represents a threat to global health and health care workers (HCWs) have an increased risk of contracting the influenza virus in the workplace. The COVID-19 pandemic has brought back the importance of influenza vaccination, as the influenza virus can circulate together with SARS-CoV-2. The aim of this report is to describe the actual flu vaccination coverage among healthcare workers of a research hospital and the trend changes, with respect to the past flu vaccination campaigns, in light of the present pandemic and COVID-19 vaccination. A Pearson’s χ2 test was used to test the correlation of flu vaccination coverage, across all professional categories, between the last two years. A linear regression model was adopted to predict the total vaccination coverage of this year. A statistically significant decrease (p < 0.01) was observed in vaccination coverage among all the professional categories with a 50% reduction in vaccination trends between the last two years. Analyzing the data from the previous six flu vaccination campaigns, the expected value, according to the linear regression model, was estimated to be 38.5% while the observed value was 24%. The decrease in vaccination coverage may be due to the fear of the pandemic situation and especially to the uncertainty related to the consequences of a concurrent administration which may overload the immune system or may be more reactogenic. The COVID-19 pandemic represents an opportunity to promote and support large-scale influenza vaccination among HCWs through structured programs, adequate funding, and tailored communication strategies.

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
Pfizer-BioNTech BNT162b2 is one of the three U.S. Food and Drug Administration (FDA)-approved vaccines for the prevention of COVID-19. Its most common side effect, injection site pain, occurs because of locally recruited inflammatory mediators and is mitigated by the lymphatic system. Side effects may discourage individuals from receiving vaccines; therefore, reducing the duration of injection site pain can promote vaccination compliance. Osteopathic manipulative treatments (OMT) can directly affect the physiology underlying muscle soreness; however, there is currently no literature that supports the use of OMT in this scenario. In this case report, an otherwise healthy male presented with acute left deltoid soreness after receiving the Pfizer COVID-19 vaccine. The pain began 5 h prior to the visit. Three hours after being treated with lymphatic OMT, the severity of the pain was significantly reduced and was alleviated 8h after onset in comparison to the median duration of 24-48 h. He received his second dose 3 weeks later. This case report can provide future studies with the groundwork for further investigating the role of OMT in treating postvaccination muscle soreness, which can improve patient satisfaction and potentially promote vaccination compliance.

Abstract
AIMS AND OBJECTIVES To explore the determinants of and behaviour change models for seasonal influenza vaccination compliance among healthcare personnel. BACKGROUND COVID-19 vaccine hesitancy among healthcare personnel may be better understood by exploring determinants of seasonal influenza vaccine hesitancy. DESIGN Integrative literature review. METHODS A systematic search was conducted in accordance with PRISMA guidelines. Six thousand and forty-eight articles were screened. Seventy-eight met inclusion criteria. Due to the heterogeneity of included articles, a narrative synthesis was conducted utilising a conceptual matrix to identify thematic categories. RESULTS Six thematic categories were identified as influencing HCP SIV compliance: 'perceived vulnerability', 'trust', 'past behaviour', 'professional duty', 'access and convenience' and 'knowledge and experience'. The Health Belief Model (HBM) was the most commonly utilised health behaviour change model within the seasonal influenza vaccination context. Few studies have examined seasonal influenza vaccine acceptance and uptake within the Australian HCP context, particularly involving community care and aged care. CONCLUSIONS Factors that appear to relate to influenza vaccination compliance among HCP can be grouped according to several thematic categories, and they also appear influential in COVID-19 vaccine uptake. In particular, an emerging focus on 'trust' or the more emotive considerations of decision-making around health-protective behaviours requires further exploration in the context of a pandemic. Efforts to influence these domains to increase compliance, however, are likely to be impeded by a lack of a well-developed and tested behaviour change model. RELEVANCE TO CLINICAL PRACTICE Healthcare personnel (HCP) face high levels of occupational exposure to seasonal influenza every year. An emerging focus on 'trust' and the more emotive considerations of decision-making around health-protective behaviours requires further exploration in the context of a pandemic.

Vaccine 2021; 39:5954-5962. [PMID: 34462164 DOI: 10.1016/j.vaccine.2021.07.082] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Revised: 06/04/2021] [Accepted: 07/28/2021] [Indexed: 11/15/2022]
Abstract
The influenza vaccine is free to all healthcare workers (HCWs) working in hospitals and long-term/residential health care facilities in Ireland. To evaluate influenza vaccine uptake, the Health Service Executive-Health Protection Surveillance Centre surveyed HCWs each season between 2011-2012 and 2019-2020. The national HCW uptake target was 40% for the first six seasons and was increased to 75% for the 2019-2020 season. Data on seasonal influenza vaccine uptake among HCWs employed in these healthcare settings were obtained using web-based surveys sent to occupational or management contact points. Data on numbers of staff vaccinated by Health Service Executive (HSE) professional staff grade and numbers eligible for vaccination in each grade were provided. Since the 2017-2018 season, a point prevalence survey for residents to assess influenza vaccine uptake has also been undertaken in long-term/residential care facilities (LTCFs) and aggregate data submitted, initially using a desktop spreadsheet survey tool, but later using web-based survey tools; these surveys were undertaken to investigate how uptake differed between HCWs and residents, both long-term and short-term. Participation by healthcare facilities and influenza vaccine uptake by both HCWs and LTCF-residents in these surveys increased over the nine seasons. Uptake among HCWs employed in publicly-funded hospitals increased from 18.1% (2011-2012) to 58.9% (2019-2020). Uptake in publicly-funded LTCFs increased from 17.8% (2011-2012) to 45.5% (2019-2020). Overall, uptake among hospital nursing staff was lowest among all staff categories for most seasons, but increased from 12.4% in 2011-2012 to 58.1% in 2019-2020. In all seasons since 2011-2012, medical/dental, management/administrative or health and social care professional staff reported the highest uptake values in public LTCFs. Of the three annual point prevalence surveys between 2017-2018 and 2019-2020, all showed high overall uptake among long-term residents (between 88.9% and 89.4%), and a lower and wider uptake range among respite residents (between 57.5% and 66.5%).

Abstract
The purpose of this study is to evaluate the attitudes of healthcare professionals toward the COVID -19 vaccine, which has been introduced to healthcare professionals at the beginning of 2021 and give information to them on the disease and vaccine. This cross-sectional analytical study has been performed by conducting an online survey to the healthcare professionals who work at the healthcare institutions in the province of Samsun in Turkey between December 2020 and January 2021. In addition to sixteen questions about the demographic characteristics, the "Attitudes towards the COVID -19 vaccine" scale has been used. MANOVA test and Spearman rho correlation coefficient were used in analytical examinations. A total of 1426 healthcare professional have been reached. 64.3% of participants were female, 44.1% were nurse/midwife and 66.6% were public employees. Regarding the questions in the sub-dimension of positive attitude, the rate of response of "I agree/I strongly agree" was between 40.6% and 54.6%. Positive attitude mean values differ according to gender, age, institution, presence of children, smoking status, being a relative who died due to COVID -19, and profession (respectively p < .001, p < .001, p < .001, p < .001, p = .002, p = .019, p < .001). It has been observed that positive and negative attitudes toward COVID -19 vaccination are almost equally distributed and some demographic factors affect the attitude. The opinions of healthcare professionals on the safety and effectiveness of the vaccine, which are the main elements of the vaccination effort, may affect the public perception of vaccination.

Abstract
BACKGROUND The World Health Organization recommends vaccination rates of 75% against seasonal influenza for patients over 65 years old. In the 2013/2014 season, the German vaccination rates ranged between 14 and 65%. This study aimed to compare the attitudes, personal characteristics and vaccination behaviours of general practitioners (GPs) in regions with high and low vaccination rates in Germany. METHODS In May 2016, a questionnaire was sent to 1594 GPs practising in 16 districts with the highest and the lowest vaccination rates in Western and Eastern Germany as described by the Central Research Institute of Ambulatory Health Care in Germany for the 2013/2014 season. Descriptive statistics and multiple regression analyses were computed to identify potential factors associated with high vaccination rates. RESULTS A total response rate of 32% (515/1594 participants) was observed in the study. GPs reported their attitudes towards vaccination in general and vaccination against influenza as mostly 'very positive' (80%, n = 352 and 65%, n = 288, respectively). GPs practising in regions with low vaccination rates reported their attitudes towards vaccinations in general (p = 0.004) and towards influenza vaccination (p = 0.001) more negatively than their colleagues from regions with high vaccination rates. Multiple logistic regression identified an increasing influence of year-dependent changing efficiency on GPs' influenza rates as the strongest factor for predicting GPs from highly vaccinating regions (OR = 4.31 [1.12-16.60]), followed by the patient's vaccination refusal despite GP advice due to already receiving a vaccination from another physician (OR = 3.20 [1.89-5.43]) and vaccination information gathering through medical colleagues (OR = 2.26 [1.19-4.29]). CONCLUSIONS The results of this study suggest a correlation between GPs' attitudes and regional vaccination rates. Beneath GPs' individual attitudes, the regional attitude patterns of patients, colleagues and medical assistants surrounding those GPs seem decisive and should be integrated into future campaigns to increase vaccination rates at a regional level.

Abstract
Objective: This study aims to determine the acceptability of a COVID-19 vaccine among healthcare workers in Saudi Arabia and the factors affecting their intention to accept the vaccine. Methods: The study used data from an online cross-sectional survey that was conducted in Saudi Arabia between 8 December 2020 and 14 December 2020. This study employed bivariate and multivariable regression analyses. The bivariate was used to describe and tabulate the frequency of all the variables, including the sociodemographic characteristics, the risk perception and the acceptance of the COVID-19 vaccination and a chi-squared test of independence was calculated. Multivariable logistic regression models were employed to examine and identify the factors associated with an intention to have the COVID-19 vaccination and the factors associated with its immediate acceptance. Results: Of the total of 736 healthcare workers who began the online questionnaire, 673 completed it (a 91.44% completion rate). Among the study participants, 50.52% were willing to have the COVID-19 vaccine, of which 49.71% intended to have the vaccine as soon as it becomes available in the country, while 50.29% would delay until the vaccine's safety is confirmed. Being a male healthcare worker, perceiving a high risk of infection, and believing that the COVID-19 vaccine should be compulsory for all citizens and residents in the country increased the probability of intention to vaccinate against COVID-19 and the probability of accepting the COVID-19 vaccination as soon as possible. Conclusion: This study calls for more health-related education among healthcare workers to alleviate any fears that might be associated with the COVID-19 vaccine.

Abstract
Background and Objective Several cases of facial paralysis have been reported following influenza vaccination; however, recent surveillance studies have not shown an increased risk. In this study, we analyzed the vaccine adverse event reporting system (VAERS) data to determine whether the facial paralysis reporting rate is higher in those who received influenza vaccination compared with those who received other vaccines. Methods We evaluated reports of facial paralysis in people who received influenza vaccination during January 2015 to October 2019 using Medical Dictionary for Regulatory Activities Preferred Terms. A disproportionality analysis was performed to determine the proportional reporting ratio (PRR), Chi-square statistic, and reporting odds ratio (ROR) with 95% confidence interval (CI). The demographic and clinical characteristics of the cases were also analyzed. Results Two hundred fifty cases of facial paralysis following influenza vaccination were reported during the study period. The median age of the patients was 45 (interquartile range, 30–57) years; 132 (52.8%) patients were females. The majority of the patients received the injected trivalent or quadrivalent seasonal influenza vaccine by intramuscular route. The PRR, Chi-square statistic, and ROR (95% CI) was 2.44, 122.32, and 2.44 (2.08–2.88), respectively; on excluding cases involving concomitant paresis/paralysis of limbs or Guillain–Barre syndrome, the disproportionality statistics were 2.30, 89.37, and 2.30 (1.93–2.75), respectively. Conclusions Our study shows increased reporting of facial paralysis following influenza vaccination as compared with other vaccines. Considering the inherent limitations of the VAERS database analysis, and the fact that disproportionality measures only indicate the presence of a signal, our study findings need to be explored in well-designed prospective pharmacoepidemiologic studies.

Abstract
BACKGROUND The important role of vaccination and preventive health care has been shown in several studies conducted worldwide. Despite the annual high infection rate of influenza, there are still many people who opt not to get vaccinated and be protected. We conducted this study to explore the knowledge, practices, and barriers of a Saudi Arabian population toward influenza vaccination. METHODS We conducted a community-based cross-sectional study using a questionnaire that was distributed online through social media to adult males and females aged 18 years old and above in Riyadh, Saudi Arabia. RESULTS A total of 778 individuals responded to the survey, 193 (24.8%) males and 585 (75.2%) females. Male respondents tended to have a better knowledge of influenza and flu vaccine than females. However, there were more females who have been vaccinated. More males believed that they do not belong to the high-risk group compared to females (P < 0.001). The younger age group of respondents significantly had a better knowledge of flu vaccine and influenza (P < 0.05). On the other hand, the older age group of respondents (age 45-60 and age >60 years old) have more reasons and barriers to have the vaccine. CONCLUSION Knowledge of influenza and flu vaccine is relatively high, but the translation of this knowledge into practice is poor. The paradigm shift should be focused not only on knowledge of vaccines and vaccination but to attitudes and practices that will address barriers to getting the vaccine.

Abstract
OBJECTIVES The objective of this survey was to analyse vaccination rates and attitudes towards vaccination among health care workers (HCWs). The period prevalence of self-reported acute respiratory infections in the influenza season 2014/2015 was examined. STUDY DESIGN A cross-sectional study was conducted among HCWs of a German university hospital using an anonymised questionnaire. Recruitment was performed by providing all medical and nursing staff a paper questionnaire with an invitation to participate. METHODS Descriptive aggregated data were generated from digitalised questionnaires for all variables. Differences in categorical variables were analysed by Chi-squared test. Textual data were analysed by an iterative process based on the grounded theory by Glaser and Strauss. RESULTS The response rate was 31% (677/2186). Probable influenza was described by 9% (64/677) of the participants. The overall self-reported vaccination rate was 55% (366/666). Self-reported vaccination rate was higher in physicians (172/239, 72%) than in nursing staff (188/418, 45%). HCWs in paediatrics (103/148, 70%) more likely received vaccines than HCWs in surgery (31/84, 37%). Most vaccinations were provided by medical staff on the wards (164/368, 45%). Self-reported lost work-time due to adverse events after vaccination was low (6/336, 2%). Eight categories for vaccine refusal were identified, whereof doubts about effectiveness and indication of the vaccine was most frequently mentioned (72/202, 36%). CONCLUSIONS Efforts to promote vaccination should focus on nursing staff and should provide scientific evidence on effectiveness, adverse effects, and the benefits of health care workers' vaccination for patients. Administering vaccines at the workplace proved to be a successful strategy in our setting. Studies are needed to assess the frequency of influenza causing disease in HCWs.

Abstract
OBJECTIVES The success of vaccination strategies depends in part on population perceptions of benefits and risks of vaccines and related confidence in vaccination. Better knowledge of public concerns about vaccines and what is driving them is needed to inform vaccination strategies and communications. This literature reviewer examined studies on vaccine and vaccination risk perceptions and concerns across European populations. METHODS A systematic literature review was conducted to identify studies published between 2004 and 2014 in Europe. A descriptive analysis was performed. FINDINGS A total of 145 articles were selected, most of which were conducted in the UK, the Netherlands and France and studied seasonal influenza, HPV and pandemic influenza vaccination. Across all countries and vaccines, the primary area of concern was vaccine safety, followed by perceptions of low likelihood of contracting vaccine-preventable diseases (VPDs), perceived low severity of VPDs, beliefs that vaccines do not work, and overall lack of information. Concerns were found to be vaccine-, country- and population-specific. CONCLUSION In addition to identifying concerns about vaccination in Europe, this study confirmed the notion that individuals have many safety concerns about vaccination and often believe that the risks of vaccination outweigh their benefits. More research needs to be conducted to explore the impact of different types of communication strategies, which would frame the benefits of vaccination as well as risks of not vaccinating. Strategies to better inform public perceptions of vaccines should include the provision of unbiased, comprehensive information tailored to population information needs, and delivered using multiple and new communication technologies such as social media.

Abstract
Influenza vaccination is strongly recommended for Italian healthcare professionals, but vaccine coverage is low. Since 2012, vaccination is also offered to medical students as part of the National Immunization Plan; however, few Medical Schools has implemented the plan so far. To study determinants of vaccination compliance, we conducted a survey among medical students at the University of Bari, where influenza vaccination has been actively offered since 2013. Information was obtained by means of an online anonymous questionnaire administered in April 2014. We enrolled 669 students, 383 (57%) vaccinated; 54% were female and the average age was 23.9 ± 4.9 y. Determinants of getting vaccinated were analyzed in a multivariate logistic model. Receiving invitation from the University (aOR = 3.8; 95%CI = 1.2-12.3; p = 0.026), the opinion that vaccine is safe (aOR = 2.8; 95%CI = 1.5-5.0; p = 0.001) and useful (aOR = 3.4; 95%CI = 1.7-6.7; p<0.0001), a specific training about influenza vaccination during the course (aOR = 1.5; 95%CI = 1.1-2.1; p = 0.043), and considering himself as at a major risk of influenza complication (aOR = 1.8; 95% CI = 1.1-2.9; p = 0.001) were significantly associated with vaccine acceptance. Active invitation and training are confirmed as key actions (as in children vaccination strategies) and, according to our results, they could be routinely used to promote vaccination in hard-to-reach groups such as healthcare workers.

Abstract
BACKGROUND Despite studies demonstrating that the annual influenza vaccination of healthcare workers reduces morbidity and mortality among vulnerable patients, vaccination rates remain very low, particularly in nursing staff. Educational programmes have failed to improve rates, which has led to a diverse range of enforced approaches being advocated and implemented. OBJECTIVES To examine the attitudes of non-vaccinated nursing staff towards various enforced measures aimed at increasing rates of influenza vaccination. METHODS Semi-structured qualitative interviews with a purposive sample of 18 non-vaccinated nurses, working in units with high-risk patients at two hospitals in Switzerland. Analysis of interviews was done using conventional content analysis. RESULTS Nurses were critical of enforced measures. However, measures that include an element of choice were perceived as more acceptable. Declination forms and mandatory vaccinations as part of the employment requirements were found to be the most accepted measures. CONCLUSION The perception of choice is crucial to the acceptance of a measure. Respect for choice and autonomy has a positive effect on behavioural change. Mandatory influenza vaccination as a condition of new (and perhaps ongoing) employment could be a feasible, effective and ethical measure to increase vaccination rates among nurses who oppose vaccination.

Abstract
Healthcare workers (HCWs) are often referred to as the most trusted source of vaccine-related information for their patients. However, the evidence suggests that a number of HCWs are vaccine-hesitant. This study consists of 65 semi-structured interviews with vaccine providers in Croatia, France, Greece, and Romania to investigate concerns HCWs might have about vaccination. The results revealed that vaccine hesitancy is present in all four countries among vaccine providers. The most important concern across all countries was the fear of vaccine side effects. New vaccines were singled out due to perceived lack of testing for vaccine safety and efficacy. Furthermore, while high trust in health authorities was expressed by HCWs, there was also strong mistrust of pharmaceutical companies due to perceived financial interests and lack of communication about side effects. The notion that it is a doctor's responsibility to respond to hesitant patients was reported in all countries. Concerns were also seen to be country- and context-specific. Strategies to improve confidence in vaccines should be adapted to the specific political, social, cultural and economic context of countries. Furthermore, while most interventions focus on education and improving information about vaccine safety, effectiveness, or the need for vaccines, concerns raised in this study identify other determinants of hesitancy that need addressing. The representativeness of the views of the interviewed HCWs must be interpreted with caution. This a qualitative study with a small sample size that included geographical areas where vaccination uptake was lower or where hesitancy was more prevalent and it reflects individual participants' beliefs and attitudes toward the topic. As HCWs have the potential of influencing patient vaccination uptake, it is crucial to improve their confidence in vaccination and engage them in activities targeting vaccine hesitancy among their patients.

Abstract
BACKGROUND Patterns of contacts between health care workers and patients during seasonal epidemics are unknown. Our study objective was to compare the number and duration of contacts between health care workers and patients during a nonepidemic period versus a community influenza epidemic, and to identify supercontactors. METHODS Our observational study was conducted in a short-stay geriatric unit of a university hospital. Contacts between individuals were recorded by active radio frequency identification devices. Contact patterns were compared between 2 periods according to contact number and duration. Each care period lasted 5 days in the nonepidemic and influenza epidemic periods. RESULTS The study included 21 medical doctors, 43 nurses, and 56 patients. In total, 3,200 contacts (61.4%; 152,700 seconds) were recorded during the nonepidemic period, with 2,013 contacts (38.6%; 92,740 seconds) in the epidemic period (P = .007). More cumulative contacts occurred during the nonepidemic period between nurses and patients (n = 2,638 [82%] vs n = 1,599 [79%]), but not between patients (n = 56 [18%] vs n = 414 [21%]). Contact duration between nurses and patients lasted longer during the nonepidemic period (P = .04). During the epidemic period, 6 nurses (15%) considered to be supercontactors accounted for 44.3% of the total number of contacts with patients. CONCLUSION The pattern of contacts between individuals differed according to the presence or not of the community influenza peak that might have influenced the risk of nosocomial influenza.

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.

Objetivo Los trabajadores sanitarios tienen riesgo de adquirir la gripe y actuar como vectores para la transmisión nosocomial. El objetivo del estudio fue la valoración de los conocimientos y actitudes de los profesionales sobre la vacunación antigripal, y determinar los factores asociados a ella por parte de profesionales de atención primaria en Cataluña. Diseño Estudio transversal mediante una encuesta anónima vía web. Emplazamiento Profesionales sanitarios de atención primaria del Instituto Catalán de la Salud. 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 Influenza vaccination is recommended for all healthcare personnel (HCP) and most institutions offer vaccination for free and on site. However, medical students do not always have such easy access, and the predictors that might guide the motivation of medical students to get vaccinated are largely unknown. Methods We conducted a cross-sectional survey study among pre-clinical medical students in a German University hospital to assess the social cognitive predictors of influenza vaccination, as well as reasons for refusal and acceptance of the vaccine. Results Findings show that pre-clinical medical students have comparable knowledge gaps and negative attitudes towards influenza vaccination that have previously been reported among HCP. Lower injunctive norms and higher feelings of autonomy contribute to no intention to get vaccinated against influenza, while a positive instrumental attitude and higher feelings of autonomy contribute to a high intention to get vaccinated. The variables in the regression model explained 20% of the variance in intention to get vaccinated. Conclusions The identified factors should be addressed early in medical education, and hospitals might benefit from a more inclusive vaccination program and accessibility of free vaccines for their medical students.

Abstract
Despite decades of effort to encourage healthcare workers (HCWs) to be immunized, vaccination rates remain insufficient. Among German HCWs, 831 (68.4%) of 1,215 respondents supported mandatory vaccinations for HCWs in general. However, acceptance of mandatory vaccination varied significantly between physicians and nurses and also depended on the targeted disease.

Abstract
Health Authorities recommend annual vaccination of healthcare personnel (HCP) against influenza to protect vulnerable patients. Nevertheless, vaccination rates have been low among European HCP. Here we report on a longitudinal survey study to identify social cognitive predictors of the motivation to obtain influenza vaccination, and to test whether intention is a good predictor of actual vaccination behaviour. Dutch HCP (N=1370) were invited to participate in a survey (baseline). To link intention to behaviour, participants who completed the first survey (N=556) were sent a second survey after vaccinations were offered (follow-up). Multinominal regression analysis showed that HCP with a positive attitude and a higher frequency of past vaccinations were more likely to have a high intention to get vaccinated. A negative attitude, high feelings of autonomy in the decision whether to get vaccinated, a preference of inaction over vaccination, a lesser sense of personal responsibility, and high self-protection motives increased the probability of no intention to get vaccinated. Social cognitive predictors were identified that explain the intention to get vaccinated against influenza of HCP, which in turn proved to be a good predictor of behaviour. Future interventions should focus on these variables to increase vaccination coverage rates.

Abstract
Seasonal influenza vaccination coverage in most EU/EEA remains suboptimal. Providers’ and users’ confidence in influenza vaccines is undermined by reports of moderate to low vaccine effectiveness and by the lack of solid evidence on disease burden. A study from Preaud and co. indicates that even with current levels of vaccine effectiveness, increasing vaccination coverage would significantly reduce disease burden and health cost. The results of the study should be interpreted cautiously because some of the assumptions are not generalizable or are imprecise, especially those on vaccine coverage, disease burden and health cost. Increasing vaccination coverage in EU/EEA countries is very challenging. Multifaceted approaches and country specific strategies are needed to address vaccine hesitancy in health care workers and in the population, and to manage organisational and financial obstacles. One key element for increasing vaccination coverage is the development of better influenza vaccines, e.g. vaccines that are more effective, provide longer lasting immunity and do not require annual administration. Vaccine producers should consider this as the highest research priority in the field of influenza vaccine development.

Abstract
Healthcare workers (HCWs) can be an important source of transmission of influenza to patients and family members, and their well-being is fundamental to the maintenance of healthcare services during influenza outbreaks and pandemics. Unfortunately, studies have shown consistently low levels of compliance with influenza vaccination among HCWs, a finding that became particularly pronounced during recent pandemic vaccination campaigns. Among the variables associated with vaccine acceptance in this group are demographic factors, fears and concerns over vaccine safety and efficacy, perceptions of risk and personal vulnerability, past vaccination behaviours and experience with influenza illness, as well as certain situational and organisational constructs. We report the findings of a review of the literature on these factors and highlight some important challenges in interpreting the data. In particular, we point out the need for longitudinal study designs, as well as focused research and interventions that are adapted to the most resistant HCW groups. Multi-pronged strategies are an important step forward in ensuring that future influenza vaccination campaigns, whether directed at seasonal or pandemic strains, will be successful in ensuring broad coverage among HCWs.

Abstract
OBJECTIVE To evaluate trends in seasonal influenza vaccination coverage in primary healthcare workers (PHCWs) in Spain between 2008 and 2011. METHODS We made an anonymous web survey of PHCWs in 2012. Information on attitudes towards and knowledge of influenza vaccine, and immunization in previous seasons was collected. Self-reported vaccination coverage and factors related to vaccination continuity were analysed. RESULTS Of 5433 workers contacted, 2625 (48.3%) responded to the survey: 47.0% were general practitioners, 10.3% paediatricians and 42.7% nurses. Their reported vaccination rates from seasons 2008-2009 to 2011-2012 decreased over time: 58.4%, 57.4%, 53.2% and 49.3% (linear trend, p < 0.001). Among workers vaccinated in any previous season, 70.2% were vaccinated again in 2011-2012, compared with 5.2% among those not previously vaccinated (p < 0.001). Continuity of vaccination increased with age and with the worker or cohabitant having a major chronic condition. Vaccination was higher in workers who recognized vaccination as effective and those worried about being infected or infecting patients. CONCLUSION Influenza vaccination coverage in PHCWs has declined, especially after the pandemic. Intensive interventions are needed to change this trend. Knowledge of vaccination should be reinforced by stressing the effectiveness of the vaccine and the risks of influenza for workers and patients.

Abstract
BACKGROUND One of the major concerns related to the pandemic outbreak of H1N1 influenza in 2009 was the cost burden on medical resources, which led to a negative impact on mortality and morbidity. This situation placed healthcare workers (HCWs) in an unusual position of being both the main actors and one of the main targets of the prevention strategies against the 2009 pandemic influenza A (H1N1). AIM The aim of the study was to find out and compare the acceptance of H1N1 vaccine among different categories of primary HCWs in primary healthcare centres in Abha as well as to explore the reasons among them for not accepting the HINI vaccine. SUBJECTS AND METHODS A cross-sectional study was conducted including all HCWs serving at primary healthcare centres in Abha. A self-administered validated questionnaire was used to collect data reflecting the intake of H1N1 vaccine and its association with other parameters that may influence the uptake of this vaccine. RESULTS The overall response rate was 347/402 (86.3%). The age of the participants ranged between 22 and 59 years with a mean of 34.9 years and SD of 8.4 years. The percentage of physicians, nurses and technicians who took the H1N1 vaccination was 32.6, 28 and 10%, respectively. The overall vaccine intake rate was 28.2%. The main reasons given by HCWs for being immunized were personal protection (51%), fear of transmitting disease to their family and relatives (49%) and fear of transmitting the disease to their patients (43.9%). The main reasons given by HCWs for rejecting H1N1 vaccination were fear of side effects (70.3%) and doubts regarding the safety of the vaccine (68.3%). In general, knowledge about H1N1 was insufficient. However, it was better among physicians than among nurses and technicians. CONCLUSION The low rate of acceptance of the pandemic vaccine and the insufficient level of knowledge about the H1N1 virus among Saudi HCWs were alarming given that they were considered models for patients and the public.

Abstract
Influenza infections have been shown to spread in hospitals rapidly; nosocomial transmissions occur frequently. Influenza vaccination of health care personnel (HCP) is an effective strategy for preventing influenza infections among personnel and patients. In summer 2011 we conducted an anonymous questionnaire among Hessian hospitals assessing influenza vaccination rates, kind and concept of vaccination programmes. Overall, 95.8% (68/71) of hospitals surveyed offered influenza vaccinations for HCP free of charge. Influenza vaccination rates have been recorded only by 70.4% (50/71). Over 80% (season 2009/2010: 41/50- season 2010/2011: 44/50) of hospitals questioned, mentioned influenza vaccination rates under 20%. Our findings confirm that the influenza vaccination rates might be less than the generally assumed and communicated influenza vaccination rates of 20-25%. Thirty years since the German Standing Committee on Vaccination (STIKO) recommended that all HCP get vaccinated against influenza, vaccination rates still remain below 30%. Measures to improve influenza vaccination rates among HCP are required. Monitoring of vaccination rates is a precondition to assess the acceptance of a vaccination programme.

Abstract
Health care workers (HCWs) are at great risk of influenza infection and transmission. Vaccination for seasonal influenza is routinely recommended, but this strategy should be reconsidered in a pandemic situation. Between October 2009 and September 2010, a multicenter study was conducted to assess the long-term immunogenicity of the A/H1N1 2009 monovalent influenza vaccine among HCWs compared to non-health care workers (NHCWs). The influence of prior seasonal influenza vaccination was also assessed with respect to the immunogenicity of pandemic H1N1 influenza vaccine. Serum hemagglutinin inhibition titers were determined prevaccination and then at 1, 6, and 10 months after vaccination. Of the 360 enrolled HCW subjects, 289 participated in the study up to 10 months after H1N1 monovalent influenza vaccination, while 60 of 65 NHCW subjects were followed up. Seroprotection rates, seroconversion rates, and geometric mean titer (GMT) ratios fulfilled the European Union's licensure criteria for influenza A/California/7/2009 (H1N1) at 1 month after vaccination in both the HCWs and NHCWs, without any significant difference. At 6 months after vaccination, the seroprotection rate was more significantly lowered among the NHCWs than among the HCWs (P < 0.01). Overall, postvaccination (1, 6, and 10 months after vaccination) GMTs for A/California/7/2009 (H1N1) were significantly lower among the seasonal influenza vaccine recipients than among the nonrecipients (P < 0.05). In conclusion, HCWs should be encouraged to receive an annual influenza vaccination, considering the risk of repeated exposure. However, prior reception of seasonal influenza vaccine showed a negative influence on immunogenicity for the pandemic A/H1N1 2009 influenza vaccine.

Abstract
Background. Pandemic influenza vaccination rate amongst healthcare workers in England 2009/2010 was suboptimal (40.3%). Targeting medical students before they enter the healthcare workforce is an attractive future option. This study assessed the H1N1 vaccine uptake rate amongst medical students and factors that influenced this. Methods. Anonymised, self-administered questionnaire at a medical school. Results. The uptake rate amongst 126 medical students offered the vaccine was 49.2% and intended uptake amongst 77 students was 63.6%. Amongst those offered the vaccine, the strongest barriers to acceptance were fear of side effects (67.9%), lack of vaccine information (50.9%), lack of perceived risk (45.3%), and inconvenience (35.8%). Having a chronic illness (OR 3.4 (95% CI 1.2-10.2)), 4th/5th year of study (OR 3.0 (95% CI 1.3-7.1)), and correct H1N1 knowledge (OR 2.6 (95% CI 1.1-6.0)) were positively associated with uptake. Non-white ethnicity was an independent negative predictor of uptake (OR 0.4 (95% CI 0.2-0.8)). Students who accepted the H1N1 vaccine were three times more likely (OR 3.1 (95% CI 1.2-7.7)) to accept future seasonal influenza vaccination. Conclusion. Efforts to increase uptake should focus on routine introduction of influenza vaccine and creating a culture of uptake during medical school years, evidence-based education on vaccination, and improving vaccine delivery.

Abstract
Rates of vaccinations of healthcare workers with recommended vaccines are generally low in the developed countries. Our goals were to identify attitudes associated with self-reported vaccinations against pertussis and seasonal influenza among Israeli nurses in Mother and Child Healthcare Centers (MCHC) in the Haifa District. Over 100 nurses answered a self-administered questionnaire. Forty two percent of the nurses reported receiving the pertussis vaccine in the last five years and 44% reported receiving the influenza vaccine during the previous year. Attitudes toward the importance of vaccinating nurses, trust in the public health authorities and demand for autonomy were associated with receiving the pertussis vaccine. Attitudes toward the importance of vaccinating nurses and trust were associated with receiving the influenza vaccine in a bivariant analysis. However, in the logistic regression models only attitudes toward the importance of vaccinating nurses were associated with vaccinations [odds ratio (OR)- 3.66, 95% confidence interval (CI)- 1.4-9.6 for pertussis and OR- 4.53, CI-1.6-13.0 for influenza]. Jewish nurses reported more often receiving the influenza vaccine compared with the Arab nurses, whereas there was no difference between them in receiving the pertussis vaccine. Low levels of positive attitudes toward the importance of vaccinating nurses may inhibit nurses in MCHC from receiving vaccines. The demand for autonomy and low levels of trust may, in part, form these low levels of positive attitudes toward the importance of vaccinating nurses.

Abstract
Vaccines based on live viruses are attractive because they are immunogenic, cost-effective, and can be delivered by multiple routes. However, live virus vaccines also cause reactogenic side effects such as fever, myalgia, and injection site pain that have reduced their acceptance in the clinic. Several recent studies have linked vaccine-induced reactogenic side effects to production of the pro-inflammatory cytokine interleukin-1β (IL-1β) in humans. Our objective was therefore to determine whether IL-1β contributed to pathology after immunization with recombinant vesicular stomatitis virus (rVSV) vaccine vectors, and if so, to identify strategies by which IL-1β mediated pathology might be reduced without compromising immunogenicity. We found that an rVSV vaccine induced local and systemic production of IL-1β in vivo, and that accumulation of IL-1β correlated with acute pathology after rVSV immunization. rVSV-induced pathology was reduced in mice deficient in the IL-1 receptor Type I, but the IL-1R-/- mice were fully protected from lethal rechallenge with a high dose of VSV. This result demonstrated that IL-1 contributed to reactogenicity of the rVSV, but was dispensable for induction of protective immunity. The amount of IL-1β detected in mice deficient in either caspase-1 or the inflammasome adaptor molecule ASC after rVSV immunization was not significantly different than that produced by wild type animals, and caspase-1-/- and ASC-/- mice were only partially protected from rVSV-induced pathology. Those data support the idea that some of the IL-1β expressed in vivo in response to VSV may be activated by a caspase-1 and ASC-independent mechanism. Together these results suggest that rVSV vectors engineered to suppress the induction of IL-1β, or signaling through the IL-1R would be less reactogenic in vivo, but would retain their immunogenicity and protective capacity. Such rVSV would be highly desirable as either vaccine vectors or oncolytic therapies, and would likely be better tolerated in human vaccinees.

Abstract
Please cite this paper as: Hollmeyer et al. (2012) Review: interventions to increase influenza vaccination among healthcare workers in hospitals. Influenza and Other Respiratory Viruses 7(4), 604–621. Annual influenza vaccination rates among hospital healthcare workers (HCW) are almost universally low despite recommendations from WHO and public health authorities in many countries. To assist in the development of successful vaccination programmes, we reviewed studies where interventions aimed to increase the uptake of influenza vaccination among hospital HCW. We searched PUBMED from 1990 up to December 2011 for publications with predetermined search strategies and of pre‐defined criteria for inclusion or exclusion. We evaluated a large number of ‘intervention programmes’ each employing one or more ‘intervention components’ or strategies, such as easy access to vaccine or educational activities, with the goal to raise influenza vaccine uptake rates in hospital HCW during one influenza season. Included studies reported results of intervention programmes and compared the uptake with the season prior to the intervention (historical control) or to another intervention programme within the same season that started from the same set of baseline activities. Twenty‐five studies performed in eight countries met our selection criteria and described 45 distinct intervention programmes. Most studies used their own facility as historical control and evaluated only one season. The following elements were used in intervention programmes that increased vaccine uptake: provision of free vaccine, easy access to the vaccine (e.g. through mobile carts or on‐site vaccination), knowledge and behaviour modification through educational activities and/or reminders and/or incentives, management or organizational changes, such as the assignment of personnel dedicated to the intervention programme, long‐term implementation of the strategy, requiring active declination and mandatory immunization policies. The number of these components applied appeared to be proportional to the increase in uptake. If influenza uptake in hospital HCW is to be increased on sustained basis, hospital managers need to be committed to conduct a well‐designed long‐term intervention programme that includes a variety of co‐ordinated managerial and organizational elements.

Abstract
The administration of vaccines is not usually recommended in pregnant women because of a fear of severe adverse events for the fetus. However, contraindication to vaccination applies only to vaccines based on live attenuated viruses for the theoretical possibility that they might infect the fetus. In contrast, the use of several inactivated vaccines is useful and recommended. As a result of the transplacental passage of antibodies, maternal immunization can reduce the risk of vaccine-preventable diseases that may occur in the first months of life before the start or completion of the suggested vaccination schedule. One of the best examples is vaccination against influenza that can protect pregnant women from a disease that can lead to hospitalization and death in a significantly higher number of cases than in the general population and can induce protective specific antibody levels as well as being effective in infants in the first months of life. Other examples are vaccinations against tetanus, pertussis, pneumococcal infections and Haemophilus influenzae type b infection. This review analyses the advantages and limitations of maternal immunization as revealed by experience and the main publications.

J Occup Med Toxicol 2012; 7:8. [PMID: 22553942 PMCID: PMC3474162 DOI: 10.1186/1745-6673-7-8] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2012] [Accepted: 05/03/2012] [Indexed: 01/25/2023] Open
Abstract
Introduction Healthcare workers (HCW) are exposed to infectious agents. Disease surveillance is therefore needed in order to foster prevention. Methods The data of the compensation board that covers HCWs of non-governmental healthcare providers in Germany was analysed for a five-year period. For hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, the period analysed was extended to the last 15 years. The annual rate of occupational infectious diseases (OIDs) per 100,000 employees was calculated. For needlestick injuries (NSI) a rate per 1,000 employees was calculated. Results Within the five years from 2005 to 2009 a total of 384 HCV infections were recognised as OIDs (1.5/100,000 employees). Active TB was the second most frequent cause of an OID. While the numbers of HBV and HCV infections decreased, the numbers for active TB did not follow a clear pattern. Needlestick injuries (NSIs) were reported especially often at hospitals (29.9/1,000 versus 7.4/1,000 employees for all other HCWs). Conclusion Although they are declining, HCV infections remain frequent in HCWs, as do NSIs. Whether the reinforcement of the recommendations for the use of safety devices in Germany will prevent NSIs and therefore HCV infections should be closely observed.

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
In June 2009, WHO declared the maximum phase alert against H1N1 pandemic flu. Health care workers (HCWs) are considered a strategic target for prevention of the occurrence of H1N1 influenza since they had the greatest risk of acquiring infection. The objectives of our study were (1) identifying the uptake of influenza A(H1N1) 2009 monovalent vaccine by primary health care workers in the southern part of Cordoba, and (2) reporting of the adverse events occurred after vaccination. We followed 240 HCWs in 12 primary health care centres at southern part of Cordoba for vaccine uptake and the occurrence of adverse events. The coverage rate with H1N1 vaccine was 20.5% which was lower compared to seasonal influenza vaccination rate 44.2% in 2009. Males had higher H1N1 vaccination rate compared to females with no significant difference. Senior HCWs complied more with seasonal influenza vaccine while this finding was not consistent with H1N1 vaccination. Multivariate analysis showed that the only independent variable that affected H1N1 vaccine was the compliance to the seasonal flu vaccine in the past three years with OR 5.1 and 95% CI (2.4-10.8). Adverse events occurred among 26.5% of those who complied with H1N1 vaccination. Those were local pain, irritation and induration at site of injection (38.5%), fever (15.4%), fever cough and rhinorrhea (15.4%) generalized pain and lumber pains (23.1%). The low vaccination rate in this study is consistent with previous studies done in many parts of the world and in Spain. Further studies should be done to explore the factors that hindered the uptake and resistance of HCWs to vaccination to H1N1 vaccine.

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
BACKGROUND Recent guidance from related regulatory agencies and medical societies supports mandatory vaccination of healthcare workers (HCW) against influenza. At St. Jude Children's Research Hospital, a pediatric oncology referral center, more than 90% of HCWs receive vaccine each year without a policy mandating immunization. Factors associated with HCW uptake of influenza vaccines have not previously been evaluated in a high compliance rate setting. METHODS A structured, anonymous, electronic questionnaire was distributed in August 2010 to employees (HCW and non-HCW). Demographics, prior receipt of influenza vaccines, reasons for acceptance or refusal of seasonal and 2009 H1N1 pandemic vaccine, and attitudes on mandatory vaccination were assessed. RESULTS 95.0% of 925 HCWs and 63.1% of all 3227 qualifying employees responded to the survey. 93.8% and 75.2% of HCW reported receiving seasonal and 2009 H1N1 influenza vaccines, respectively, in the 2009-2010 season. Benefits to self and/or patients were cited as the most frequent reasons for accepting seasonal (83.5% and 78.3%, respectively) and 2009 H1N1 (85.9% and 81.1%, respectively) vaccination. 36.6% of HCWs opposed mandating influenza vaccination; 88.2% and 59.9% of whom reported receiving the seasonal and 2009 H1N1 influenza vaccines, respectively. Violation of freedom of choice and personal autonomy were the most frequently reported reasons for opposition. CONCLUSION In this cohort of HCWs with a high influenza vaccination rate, realistic assessments of the potential benefits of vaccination appear to have driven the choice to accept immunization. Despite this, mandating vaccination was viewed unfavorably by a significant minority of vaccinated individuals. Employee concerns over autonomy should be addressed as institutions transition to mandatory vaccination policies.
