Coverage Rates

Although several national and international recommendations have been published, influenza vaccinations are carried out too rarely and thus vaccine coverage rates, both in the general population and in risk groups, remain at an unsatisfactorily low level. The paper presents the current data describing influenza vaccine coverage rates in different countries, in the general population and risk groups (including patients with chronic diseases, pregnant women, children the elderly) and health care workers. It is emphasized that there are many limitations related to the estimation of coverage rates. Methods that are currently used for the assessment of influenza vaccination coverage rates include the following: an analysis of data from health care facilities or providers, from national health insurance records, from well-documented national or private vaccine programs targeting at specific smaller groups, evaluation of national vaccine register, and national surveys of individuals. The establishment of coverage rates among specific groups usually requires another approach with the use of individual web- or telephone- based surveys, which is why selection bias and recall bias should be taken into consideration while discussing the results. The most common drivers and barriers for influenza vaccination are also identified and presented in the review.

Abstract Background: Electronic vaccine registries are not yet widely established. There is a need to real-time monitor influenza vaccine coverage, which may raise awareness to risk groups and professionals, and eventually allow to adopt tailored measures during the vaccination campaign. To evaluate the utility of the “Gripómetro”, a demographic study designed to monitor national and regional influenza vaccine coverage on a weekly basis in Spain. Methods: Quantitative study based on surveys of the Spanish population between 18-80 years and a sample of primary care doctors and nurses randomly selected. Pre-proportional fixation has been established by Autonomous Communities and age group to guarantee the representativeness of all the autonomies. Results: Interviews were conducted in 3400 households of general population and 807 respondents among health care professionals. We found that the results of influenza vaccination coverage obtained by the Gripómetro for 2018-2019 season were mostly comparable with the official data presented by the Ministry of Health after the end of the vaccination campaign. Conclusions: The Gripómetro is a robust research method that provides real-time data and trends for influenza vaccine coverage along with other useful information related to vaccination such as intention to vaccinate, motivation and barriers to vaccination.

Influenza is a significant public health problem and the elderly are at a greater risk of contracting the disease. The vaccination coverage of the elderly is below the Spanish target of 65% for each influenza season. The aims of this study were to report the coverage of influenza vaccination in Spain among the population aged ≥65 years and high-risk groups for suffering chronic diseases, to analyze the time trends from 2006 to 2017 and to identify the factors which affect vaccination coverage. A nationwide cross-sectional study was conducted including 20,753 non-institutionalized individuals aged ≥65 years who had participated in the Spanish National Health Surveys in 2006, 2011/2012, and 2017. Sociodemographic, health-related variables, and influenza vaccination data were used. A logistic regression analysis was performed to determine the variables associated with influenza vaccination. Influenza vaccination coverage was 60%. By chronic condition, older people with high cholesterol levels and cancer had the lowest vaccination coverage (62.41% and 60.73%, respectively). This coverage declined from 2006 to 2017 in both groups. Higher influenza vaccination was associated with males, Spanish nationality, normal social support perceived, polypharmacy, worse perceived health, participation in other preventive measures, and increasing age and the number of chronic diseases.

This paper examines influenza vaccine coverage rates (VCR) in Poland and Sweden during the 2003/4 and 2004/5 influenza seasons. An average sample of 2,500 persons was interviewed in each country and each season. Questions regarded age and possible chronic diseases, as well as information on whether they had had an influenza vaccination in the given season. Those who had not received the vaccine were also asked to give reasons for non-vaccination. About one in four (Sweden) to one in three (Poland) of the persons surveyed belonged to high-risk groups (>=65 years of age or suffering from chronic diseases). In the 2004/5 season, 17% (CI 12-19%) of the Polish elderly and 45% (CI 39-50%) of the Swedish elderly were vaccinated. In Poland, 9% (CI 7-12%) of respondents younger than 65 years of age with a chronic condition were vaccinated, whereas in Sweden the corresponding rate was 12% (CI 9-16%). In both countries, the VCR did not change significantly from the previous season. Personal invitations resulted in a higher VCR. In Sweden, the most frequently mentioned reasons for not being vaccinated were the assumption of not qualifying for a vaccination and perceived resistance. In Poland in both years, perceived resistance to flu and the cost of the vaccination were the most often mentioned reasons. The influenza vaccination rates in Poland and Sweden remain far below World Health Organization (WHO) recommendations for the high-risk population. No increase in VCR as demonstrated in this study may indicate that these two countries will not be able to meet the 2010 WHO target, if no further action is taken concerning vaccine uptake.

Abstract Background Influenza vaccination coverage among elderly remains unsatisfactory even in developed countries. Since attitudes are predictors of behavior, understanding factors influencing the intention to receive influenza vaccine (IV) among elderly may orientate interventions to increase vaccination rate. The aim of the current study was to identify factors associated to willingness to receive IV next season among Tunisian elderly. Methods During 2018 -2019 flu season a cross-sectional study was conducted among older persons aged 60 years and over with chronic disease attending primary and secondary health care facilities. The intention to get vaccinated against influenza was measured by means of a face to face questionnaire. Factors that affect willingness to receive IV were identified using a multiple logistic regression analysis. Results Of the 1191 older persons included, 19.4% [17.1-21.9] participants received IV in 2018-2019 flu season, 64.7% [61.9-67.3] expressed willingness to be vaccinated next season. Willingness to receive IV was more likely among persons with chronic pulmonary disease (ORa=2.6), those suffering from diabetes (ORa=1.6), those who received IV in 2018-2019 flu season (ORa=16.5), those who feel that they get enough information about vaccines and their safety (ORa=2.9) and persons who trust the advice of their health care providers (ORa=4.5). Conclusions Vaccination status was the most determinant factor associated to willingness to receive the vaccine. Therefore, sustainable efforts to promote IV may lead to cumulative increase of influenza vaccination coverage year by year. Doctors should be involved more in advocating IV and providing elderly with the necessary information about IV, but that could not be effective without a climate of trust between patients and health care providers. Key messages Positive self-experience of older persons with IV may change their perception about it and encourage them to adhere to the vaccine in the future. Elderly should be provided with the necessary information about IV in terms of effectiveness and safety.

Abstract Background In the UK, annual influenza vaccination is currently recommended for adults aged 16–64 years who are in a clinical at-risk group. Despite recommendations, rates of vaccine uptake in the UK have historically been low and below national and international targets. This study aims to analyse vaccine uptake among adults in clinical at-risk groups from the 2015–2016 influenza season to the present. Methods A retrospective analysis of influenza vaccine coverage in the UK was conducted using data extracted from publicly available sources. Clinically at-risk individuals (as defined by Public Health England), including pregnant women, aged 16–64 years, were included in this study. Results Influenza vaccination coverage rates across the UK in adults aged 16–64 years in a clinical at-risk group have been consistently low over the past 5 years, with only 48.0, 42.4, 44.1 and 52.4% of eligible patients in England, Scotland, Wales and Northern Ireland receiving their annual influenza vaccination during the 2018–2019 influenza season. Influenza vaccine coverage was lowest in patients with morbid obesity and highest in patients with diabetes in 2018–2019. Coverage rates were below current national ambitions of ≥75% in all clinical risk groups. In these clinical at-risk groups, influenza vaccine coverage decreased between 2015 and 2019, and there was considerable regional variation. Conclusions Uptake of the influenza vaccine by adults aged 16–64 years in a clinical at-risk group was substantially below the national ambitions. As a result, many individuals in the UK remain at high risk of developing severe influenza or complications. Given that people who are vulnerable to COVID-19 are also at increased risk of complications from influenza, during the 2020–2021 season, there is a heightened need for healthcare professionals across the UK to address suboptimal vaccine uptake, particularly in at-risk patients. Healthcare professionals and policymakers should consider measures targeted at increasing access to and awareness of the clinical benefits of the influenza vaccine.

Background: There is limited information on vaccination coverage and characteristics associated with vaccine uptake in Aboriginal and/or Torres Strait Islander adults. We aimed to provide more current estimates of influenza vaccination coverage in Aboriginal adults. Methods: Self-reported vaccination status (n=559 Aboriginal and/or Torres Strait Islander participants, n=80,655 non-Indigenous participants) from the 45 and Up Study, a large cohort of adults aged 45 years or older, was used to compare influenza vaccination coverage in Aboriginal and/or Torres Strait Islander adults with coverage in non-Indigenous adults. Results: Of Aboriginal and non-Indigenous respondents aged 49 to <65 years, age-standardised influenza coverage was respectively 45.2% (95% CI 39.5–50.9%) and 38.5%, (37.9–39.0%), p-value for heterogeneity=0.02. Coverage for Aboriginal and non-Indigenous respondents aged ≥65 years was respectively 67.3% (59.9–74.7%) and 72.6% (72.2–73.0%), p-heterogeneity=0.16. Among Aboriginal adults, coverage was higher in obese than in healthy weight participants (adjusted odds ratio (aOR)=2.38, 95%CI 1.44–3.94); in those aged <65 years with a medical risk factor than in those without medical risk factors (aOR=2.13, 1.37–3.30); and in those who rated their health as fair/poor compared to those who rated it excellent (aOR=2.57, 1.26–5.20). Similar associations were found among non-Indigenous adults. Conclusions: In this sample of adults ≥65 years, self-reported influenza vaccine coverage was not significantly different between Aboriginal and non-Indigenous adults whereas in those <65 years, coverage was higher among Aboriginal adults. Overall, coverage in the whole cohort was suboptimal. If these findings are replicated in other samples and in the Australian Immunisation Register, it suggests that measures to improve uptake, such as communication about the importance of influenza vaccine and more effective reminder systems, are needed among adults.
