“…Similar to previous studies, 25,28 we found that subjects who received influenza vaccination perceived more benefits from vaccination and had fewer barriers to receiving vaccination than did individuals who did not receive vaccination. Inaccessibility reduced the willingness to receive influenza vaccination in the group of diabetes patients.…”

“…24 Despite the In addition, many health workers are not convinced of the safety and effectiveness of influenza vaccination. 9,25 Our study also found that adults aged 65 y and older were more likely to receive influenza vaccination from 2011-2012 than younger adults, aged 40-64 y, were (57% vs. 16%). That the Taiwanese government did not provide free influenza vaccination for people younger than 65 y of age may be one of the reasons for lower influenza vaccination coverage among younger diabetic patients.…”

The purpose of this study was to investigate influenza vaccination coverage and the factors influencing acceptance of influenza vaccination among patients with diabetes in Taiwan using the Health Belief Model (HBM). From January 1 to February 28, 2012, 700 patients with diabetes who visited National Cheng Kung University Hospital were invited to participate in the study. A total of 691 (99%) patients with diabetes were enrolled in the study. The mean age of the subjects was 64.7 years (SD = 10.7). The percentages of patients with diabetes who received seasonal influenza vaccination were 31%, 33%, and 35% in 2009-2010, 2010-2011, and 2011-2012, respectively. Multiple regression analyses revealed that patients with diabetes who were female, were older, had comorbidities, had a more positive perception of the benefits of the influenza vaccine and had lower perceived barriers to influenza vaccination were more likely to receive the influenza vaccine in 2011-2012 (adjusted R(2) = 0.47; Chi-square = 276.50; P<0.001). Patients with diabetes perceived the risk of swine influenza to be similar to that of seasonal influenza. Consequently, in the absence of an increase in the perceived risk of influenza, a low level of actual vaccination against seasonal influenza is forecasted. Strategies to improve the uptake of influenza vaccination include interventions that highlight the risk posed by pandemic influenza while simultaneously offering tactics to ameliorate this risk.

“…Moreover, only one third of ever vaccinated older persons is being immunized every season. The proportion of ever vaccinated older persons in our study is similar to that reported in Taiwan (43.7%, for the last analyzed vaccination season of 2008–2009) [27]. Also, slightly higher proportion (58.6%) of vaccinated seniors was documented in Spain [28].…”

BackgroundSurveys of older adults’ knowledge relative to flu immunization have highlighted its relevance in the improvement of vaccination coverage. The purpose of this study was to estimate the proportion of older persons who have ever been immunized against seasonal flu in the municipality of Vračar (Belgrade, Serbia), assess their knowledge related to flu and flu vaccination, and to determine factors associated with flu immunization.MethodsIn the period November 2012–January 2013, 480 persons aged above 65 years were recruited at the Community Health Center, of which 354 persons were finally included in the study. Data were collected using a questionnaire. To assess the level of knowledge, correct answers were awarded 1 point. The total knowledge score ranged from 0 to 17 and was divided into three levels: poor (0–4 points), moderate (5–8 points), good (9–13 points), and excellent (14–17 points).ResultsThe proportion of ever vaccinated older persons was 47.7%. Of those, one third (29.1%) had been immunized regularly. Most seniors (61.9%) demonstrated good, whereas one third (29.8%) demonstrated excellent level of knowledge. In terms of reasons for non-compliance, the highest proportion of older persons declined vaccination because “they were in good health” (33.5%) and because “they did not believe that vaccine protects from flu” (31.5%). Independent predictors of being ever immunized against seasonal flu were having higher level of education, being more knowledgeable relative to flu vaccination, and taking more medications.ConclusionsOur results indicate that health care sector requires well-coordinated promotion campaigns to enhance acceptance of flu vaccination. Organized immunization counseling could provide accurate, evidence-based information in order to transform misbeliefs, prejudice, and negative attitude towards vaccination.Electronic supplementary materialThe online version of this article (10.1186/s41043-018-0159-8) contains supplementary material, which is available to authorized users.

“…When analyzed by type/subtype, the reduction was 40% (95% CI = 26-52) for influenza A(H3N2) and 90% (95% CI = 51-98) for influenza A(H1N1); no benefit was seen against influenza B (13%; 95% CI = -77-58) (170). A seven-season study (2002-03 through 2008-09) found that in every season, vaccinated elderly participants were significantly less likely to be hospitalized for P&I compared with unvaccinated persons (adjusted odds ratio [aOR] ranged from 0.67 to 0.86 over the seven seasons; p<0.001 to <0.030); no significant decrease was observed in the risk for outpatient visits (171). Several studies using methods to account for unmeasured confounding have reported that among community-dwelling older persons for nonspecific serious outcomes such as P&I hospitalizations or all-cause mortality is ~10% or less, which is more plausible than higher estimates from earlier studies (172)(173)(174).…”
