Abstract
OBJECTIVE The aim of this study was to estimate the prevalence of influenza immunization in elderly people in Brazil in 2019. METHODS This is a population-based cross-sectional study. The Brazilian individuals (≥60 years) who participated in the 2019 National Health Survey were included. The survey was conducted in permanent households in Brazil from August 2019 to March 2020. The prevalences of influenza vaccination and their respective confidence intervals (95%CI) were estimated according to sociodemographic characteristics and the diagnosis of chronic diseases. RESULTS The prevalence of influenza vaccination was 72.4% (95%CI 71.5-73.2), with statistically significant differences observed between genders (p=0.001), age groups (p=0.001), and those living with a spouse/partner (p=0.002). Significant differences were found in groups with arterial hypertension (75.2%, p<0.001), diabetes (77.2%, p<0.001), and arthritis or rheumatism (75.5%, p<0.001). CONCLUSION A global prevalence of influenza vaccination of 72.4% was estimated among elderly people in Brazil.

A complex intervention on vaccination uptake among older adults (≥ 60 years) in Germany - a study protocol with a mixed methods design. BMC PRIMARY CARE 2023; 24:148. [PMID: 37452283 PMCID: PMC10349490 DOI: 10.1186/s12875-023-02101-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Accepted: 07/03/2023] [Indexed: 07/18/2023]
Abstract
BACKGROUND The current uptake of many vaccinations recommended for persons aged 60 and older is unsatisfactory in Germany. Lack of confidence in the safety and efficacy of vaccinations, lack of knowledge and insecurities about possible side effects, and numerous pragmatic barriers are just some of the reasons to be mentioned. General practitioners (GPs) play a central role in the vaccination process. Therefore, effective interventions in this context are needed to address the various barriers and improve the vaccination uptake rates. METHODS A complex intervention will be implemented and evaluated in 1057 GPs' practices in two German federal states. The components include trainings for GPs and medical assistants on communication psychology, medical aspects, and organisational vaccination processes. The primary outcome influenza vaccination rate and the secondary outcomes vaccination uptake rate of other vaccinations as well as vaccine literacy of patients will be examined. The intervention will be evaluated in a mixed methods study with a controlled design. Survey data will be analysed descriptively and by using mean comparisons as well as multivariable multilevel analyses. The qualitative data will be analysed with qualitative content analysis. The secondary data will be analysed by using descriptive statistics, a pre-post comparison by performing mean comparisons, cluster analysis, and subgroup analyses. DISCUSSION In this study, a complex intervention to improve vaccination rates in GP practices for the vaccinations recommended for people aged 60 years and older will be implemented and evaluated. Additionally, improvements in patients' vaccine-related health literacy and knowledge, and patients' intention to get vaccinated are expected. The mixed methods design can deliver results that can be used to improve preventive health care for elderly people and to gain more knowledge on vaccination uptake and the intervention's effectiveness. TRIAL REGISTRATION Trial registration number: DRKS00027252 (retrospectively registered).

Influenza Vaccination Coverage among Older Adults with Hypertension in Shenzhen, China: A Cross-Sectional Survey during the COVID-19 Pandemic. Vaccines (Basel) 2021; 9:vaccines9101105. [PMID: 34696213 PMCID: PMC8540932 DOI: 10.3390/vaccines9101105] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2021] [Revised: 09/14/2021] [Accepted: 09/25/2021] [Indexed: 12/02/2022] Open
Abstract
Background: Older individuals with hypertension are at a high risk of being infected with influenza. However, there have been few studies investigating the influenza vaccination status among older people with hypertension. The present work aimed to estimate the vaccination coverage and determine the predictors of seasonal influenza vaccinations among hypertensive patients aged over 60 years in Shenzhen, China. Method: The study used data from an online cross-sectional survey that was conducted in Shenzhen City, China, in October 2020. Frequencies and proportions of all the variables including sociodemographic characteristics and health-related information were described and tabulated based on the influenza vaccination status. Bivariate and multivariable logistic regression analyses were used to identify independent predictors associated with the influenza vaccination. Results: A total of 5216 older people with hypertension aged above 60 years were recruited. Overall, only 4.7% had received an influenza vaccine in the latest influenza season. Using the action toward being vaccinated as the primary outcome, the multivariable regression analysis showed that participants aged over 80 years (aOR 2.957, 95% CI: 1.784–4.900), obtaining higher education levels (aOR 1.424, 95% CI: 1.060–1.914 for high school, aOR 1.681, 95% CI: 1.066–2.650 for college or above), living with a partner (aOR 1.432, 95% CI: 1.068–1.920), using a family doctor (aOR 2.275, 95% CI: 1.744–2.968), and taking a physical examination 1–2 and ≥3 times each year (aOR 2.107, 95% CI: 1.601–2.772 and aOR 2.118, 95% CI: 1.083–4.143, respectively) were more likely to be vaccinated. In contrast, smokers had less likelihood of having the influenza vaccination than non-smokers (aOR 1.829, 95% CI: 1.208–2.767). Conclusions: The coverage rate of influenza vaccinations is far away from optimistic among older adults with hypertension. Additional works should be undertaken immediately to improve the influenza vaccination status.

Abstract
Routine immunization during pandemics can be harmed. This study estimated the influenza vaccination coverage in older adults during the COVID-19 through the EPICOVID-19, a population-based study conducted in 133 cities from the 26 Brazilian states and Federal District. We selected 25 census tracts per city, with probability proportional to the tract's size, ten households by census tract, and one random individual interviewed. A total of 8,265 older adults (≥60 years old) were interviewed and asked whether they had been vaccinated against flu in 2020. Vaccination coverage was 82.3% (95% CI: 80.1-84.2) with no difference by gender, age, and region; higher vaccination coverage was observed among the wealthiest (84.7% versus 80.1% in the poorest) and among the more educated (87.3% versus 83.2% less educated); lower coverage among indigenous (56.9% versus > 80% among other ethnic groups). A positive association was identified with the number of comorbidities among men but not among women. Most of the population was vaccinated (97.5%) in the public health system. The private network was chosen mainly in the South by the wealthiest and more educated. Vaccination coverage was seven percentage points lower than the government target (90%), and inequalities should be reversed in future campaigns.
