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.

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.

College students' perceptions of H1N1 flu risk and attitudes toward vaccination.

College students are highly susceptible to the H1N1 virus, yet previous studies suggest that college students perceive themselves at low risk for the flu. We surveyed 514 undergraduates to assess their perceptions of H1N1 flu risk and opinions about flu vaccines. A third of respondents stated that they were not at risk of getting the H1N1 flu because they were young. Responses indicated a distrust of the safety and effectiveness of influenza vaccinations; only 15.8% of participants planned on receiving H1N1 vaccination. Top reasons for refusing the H1N1 vaccine included questioning vaccine safety and effectiveness, and concerns about potential serious and/or benign side effects. Top reasons for H1N1 vaccination acceptance included receiving a doctor recommendation for the vaccine, having previously gotten a seasonal vaccine, and being at high-risk for influenza. Our findings suggest that college students are inaccurate in assessing their risk level and are unlikely to seek vaccinations.

Public health worker attitudes and beliefs concerning 2009 H1N1 and seasonal influenza vaccines.

In this study examining public health workers' 2009 H1N1 and seasonal influenza vaccination uptake, a survey was conducted to assess flu vaccine acceptance, as well as behaviors and beliefs regarding acceptance, among public health workers in southeastern Tennessee. Factors found to be significantly associated with acceptance of the 2009 H1N1 vaccine were direct patient care, previous flu vaccination, vaccine safety concerns, and receipt of seasonal flu vaccine.
