Determinants of adherence to seasonal influenza vaccination among healthcare workers from an Italian region: results from a cross-sectional study.
Notwithstanding decades of efforts to increase the uptake of seasonal influenza (flu) vaccination among European healthcare workers (HCWs), the immunisation rates are still unsatisfactory. In order to understand the reasons for the low adherence to flu vaccination, a study was carried out among HCWs of two healthcare organisations in Liguria, a region in northwest Italy.
A cross-sectional study based on anonymous self-administered web questionnaires was carried out between October 2013 and February 2014. Through univariate and multivariate regression analysis, the study investigated the association between demographic and professional characteristics, knowledge, beliefs and attitudes of the study participants and (i) the seasonal flu vaccination uptake in the 2013/2014 season and (ii) the self-reported number of flu vaccination uptakes in the six consecutive seasons from 2008/2009 to 2013/2014.
A total of 830 HCWs completed the survey. Factors statistically associated with flu vaccination uptake in the 2013/2014 season were: being a medical doctor and agreeing with the statements 'flu vaccine is safe', 'HCWs have a higher risk of getting flu' and 'HCWs should receive flu vaccination every year'. A barrier to vaccination was the belief that pharmaceutical companies influence decisions about vaccination strategies.
All the above-mentioned factors, except the last one, were (significantly) associated with the number of flu vaccination uptakes self-reported by the respondents between season 2008/2009 and season 2013/2014. Other significantly associated factors appeared to be level of education, being affected by at least one chronic disease, and agreeing with mandatory flu vaccination in healthcare settings.
This survey allows us to better understand the determinants of adherence to vaccination as a fundamental preventive strategy against flu among Italian HCWs. These findings should be used to improve and customise any future promotion campaigns to overcome identified barriers to immunisation.

Knowledge, attitudes, and beliefs about seasonal influenza and H1N1 vaccinations in a low-income, public health clinic population.
The Public Health Center Vaccine Survey (PHCVS) examines the knowledge, attitudes, and beliefs about seasonal influenza and H1N1 vaccinations in a largely low-income, urban, public health clinic population in Los Angeles County, USA.
A cross-sectional survey of vulnerable individuals at risk for severe influenza infection was conducted in one of the nation's largest local public health jurisdictions.
A total of 1541 clinic patients were recruited in the waiting rooms of five large public health centers in Los Angeles County from June to August, 2010.
Among prospective respondents who met eligibility criteria, 92% completed the survey. The majority was black or Latino and most were between the ages of 18 and 44 years. More than half were unemployed; two-thirds had no health insurance; and nearly one-half reported having a high school education or less. About one-fifth reported they had received the H1N1 vaccine during the previous flu season. In comparative analyses, negative beliefs about vaccine safety and efficacy were highly predictive of H1N1 vaccination. Blacks were less likely than non-black respondents to report receiving the H1N1 vaccine (OR=0.7, 95% CI=0.6-1.0). Blacks were also less likely than other respondents to agree that vaccines can prevent disease (OR=0.4, 95% CI=0.3-0.5), that vaccines are safe (OR=0.5, 95% CI=0.4-0.6), and that they trust doctors/clinicians who recommend vaccines (OR=0.5, 95% CI=0.4-0.7).
Study findings provide a useful risk profile of vulnerable groups in Los Angeles County, which may be generalizable to other urban jurisdictions in the United States. They also describe real world situations that can be used to forecast potential challenges that vaccine beliefs may pose to national as well as local influenza pandemic planning and response, especially for communities with limited access to these preventive services.

Factors mediating seasonal and influenza A (H1N1) vaccine acceptance among ethnically diverse populations in the urban south.
We examined the acceptability of the influenza A (H1N1) and seasonal vaccinations immediately following government manufacture approval to gauge potential product uptake in minority communities. We studied correlates of vaccine acceptance including attitudes, beliefs, perceptions, and influenza immunization experiences, and sought to identify communication approaches to increase influenza vaccine coverage in community settings.
Adults ≥18 years participated in a cross-sectional survey from September through December 2009. Venue-based sampling was used to recruit participants of racial and ethnic minorities.
The sample (N=503) included mostly lower income (81.9%, n=412) participants and African Americans (79.3%, n=399). Respondents expressed greater acceptability of the H1N1 vaccination compared to seasonal flu immunization (t=2.86, p=0.005) although H1N1 vaccine acceptability was moderately low (38%, n=191). Factors associated with acceptance of the H1N1 vaccine included positive attitudes about immunizations [OR=0.23, CI (0.16, 0.33)], community perceptions of H1N1 [OR=2.15, CI (1.57, 2.95)], and having had a flu shot in the past 5 years [OR=2.50, CI (1.52, 4.10). The factors associated with acceptance of the seasonal flu vaccine included positive attitudes about immunization [OR=0.43, CI (0.32, 0.59)], community perceptions of H1N1 [OR=1.53, CI (1.16, 2.01)], and having had the flu shot in the past 5 years [OR=3.53, CI (2.16, 5.78)]. Participants were most likely to be influenced to take a flu shot by physicians [OR=1.94, CI (1.31, 2.86)]. Persons who obtained influenza vaccinations indicated that Facebook (χ(2)=11.7, p=0.02) and Twitter (χ(2)=18.1, p=0.001) could be useful vaccine communication channels and that churches (χ(2)=21.5, p<0.001) and grocery stores (χ(2)=21.5, p<0.001) would be effective "flu shot stops" in their communities.
In this population, positive vaccine attitudes and community perceptions, along with previous flu vaccination, were associated with H1N1 and seasonal influenza vaccine acceptance. Increased immunization coverage in this community may be achieved through physician communication to dispel vaccine conspiracy beliefs and discussion about vaccine protection via social media and in other community venues.
