Abstract
Background: In the latest American Heart Association guidelines, influenza vaccination is recommended for patients with peripheral arterial disease (PAD). The vaccination coverage in this specific population is currently unknown. This study aims to determine the adherence to influenza vaccination in a PAD population and identify associated determinants. Patients and methods. Hospitalized patients and outpatients with PAD from two university departments of vascular medicine were prospectively included. A questionnaire was administered to collect sociodemographic data, cardiovascular risk factors, influenza vaccination status, history of cardiovascular disease, and perception and knowledge about vaccination. Logistic regression was conducted to assess vaccination determinants. Results: Over a six-month period, 494 patients were included (median age 69.5, IQR [63-77], 78% male). Overall, 60.1% were either vaccinated or intended to be (Group 1). Vaccination was associated with age (odds-ratio [OR]=1.055, 95% confidence intervals [95%CI]: 1.035-1.075, p<0.0001), abdominal aorta aneurysm (OR=0.390, 95%CI: 0.229-0.664, p=0.001), chronic obstructive pulmonary disease (OR=0.545, 95%CI: 0.367-0.810, p=0.003), chronic renal disease (OR=0.630, 95%CI: 0.400-0.993, p=0.046), and valvulopathy (OR=2.444, 95%CI: 1.122-5.326, p=0.025). Only 25.3% received vaccination information mainly from their general practitioners. Among patients against vaccination, 59.9% considered themselves not concerned about potential influenza consequences on their PAD, and 37.6% did not intend to change their decision. Conclusions: This study highlights the low adherence to influenza vaccination in the PAD population of 2 university hospital centers. Vaccination is often related to age, and there is a need for adapted information regarding influenza consequences on cardiovascular disease overall, particularly on PAD. Addressing common information and advice about vaccination will be a challenge.

Mastrovito B, Lardon A, Dubromel A, Nave V, Beny K, Dussart C. Understanding the gap between guidelines and influenza vaccination coverage in people with diabetes: a scoping review. Front Public Health 2024; 12:1360556. [PMID: 38706547 PMCID: PMC11066301 DOI: 10.3389/fpubh.2024.1360556] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Accepted: 04/09/2024] [Indexed: 05/07/2024] Open
Abstract
Background Diabetes affects millions of people worldwide, making them more vulnerable to infections, including seasonal influenza. It is therefore particularly important for those suffering from diabetes to be vaccinated against influenza each year. However, influenza vaccination coverage remains low in this population. This review primarily aims to identify the determinants of influenza vaccination in people with diabetes (T1D or T2D). Secondly, it aims to assess main recommendations for influenza vaccination, vaccine effectiveness, vaccination coverage, and how education and pharmacists can encourage uptake of the vaccine in the diabetic population. Methods A scoping review was conducted in January 2022 to systematically review evidence on influenza vaccination in people with diabetes using data from PubMed, Science Direct, and EM Premium with terms such as "Diabetes mellitus," "Immunization Programs," "Vaccination," and "Influenza Vaccines." Quality assessment and data extraction were independently conducted by two authors. Disagreements between the authors were resolved through discussion and consensus, and if necessary, by consulting a third author. Results Of the 333 records identified, 55 studies met the eligibility criteria for inclusion in this review. Influenza vaccination was recommended for people ≥6 months. Despite effectiveness evidence showing a reduction in mortality and hospitalizations in people with diabetes vaccinated vs. non-vaccinated ones, very few studies reported a coverage rate ≥ 75%, which is WHO's target objective. Determinants such as advanced age, presence of comorbidities and healthcare givers' advice were associated with increased vaccination uptake. On the contrary, fear of adverse reactions and concerns about vaccine effectiveness were significant barriers. Finally, education and pharmacists' intervention played a key role in promoting vaccination and increasing vaccination uptake. Conclusion Influenza vaccination coverage in people with diabetes remains low despite recommendations and evidence on vaccine effectiveness. Motivators and barriers as well as several socio-demographic and clinical factors have been identified to explain this trend. Efforts are now needed to increase the number of diabetics vaccinated against influenza, mainly through education and the involvement of healthcare givers.

Abstract
INTRODUCTION The Raise Awareness of Influenza Strategies in Europe (RAISE) group gathered information about the healthcare burden of influenza (hospitalizations, intensive care unit [ICU] admissions, and excess deaths), surveillance systems, and the vaccine coverage rate (VCR) in older adults in 18 European countries and Israel. AREAS COVERED Published medical literature and official medical documentation on the influenza disease burden in the participating countries were reviewed from 2010/11 until the 2022/23 influenza seasons. Information on the framework for monitoring the disease burden and the provision for ensuring older adults had access to vaccination in their respective countries was provided. Data on influenza VCR in older adults were collected for the 2019/20 to 2022/23 influenza seasons. Data are reported descriptively. EXPERT OPINION Influenza presents a significant healthcare burden in older adults. Reporting outcomes across participating countries is heterogeneous, highlighting the need for standardized approaches. Although older adults receive free influenza vaccination, vaccine uptake is highly variable among countries. Moreover, hospitalization rates remain high even in countries reporting a high VCR. Increased awareness and education on the burden of disease and the broader use of improved influenza vaccines for older adults may help reduce the disease burden on this population.

Goldstein E. Mortality associated with Omicron and influenza infections in France before and during the COVID-19 pandemic. Epidemiol Infect 2023; 151:e148. [PMID: 37622317 PMCID: PMC10540177 DOI: 10.1017/s0950268823001358] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 05/30/2023] [Accepted: 07/25/2023] [Indexed: 08/26/2023] Open
Abstract
For many deaths associated with influenza and Omicron infections, those viruses are not detected. We applied previously developed methodology to estimate the contribution of influenza and Omicron infections to all-cause mortality in France for the 2014-2015 through the 2018-2019 influenza seasons, and the period between week 33, 2022 and week 12, 2023. For the 2014-2015 through the 2018-2019 seasons, influenza was associated with annual average of 15,654 (95% CI (13,013, 18,340)) deaths, while between week 33, 2022 and week 12, 2023, we estimated 7,851 (5,213, 10,463) influenza-associated deaths and 32,607 (20,794, 44,496) SARS-CoV-2 associated deaths. For many Omicron-associated deaths for cardiac disease, mental&behavioural disorders, and other causes, Omicron infections are not characterised as a contributing cause of death - for example, between weeks 33-52 in 2022, we estimated 23,983 (15,307, 32,620) SARS-CoV-2-associated deaths in France, compared with 12,811 deaths with COVID-19 listed on death certificate. Our results suggest the need for boosting influenza vaccination coverage in different population groups in France, and for wider detection of influenza infections in respiratory illness episodes (including pneumonia) in combination with the use of antiviral medications. For Omicron epidemics, wider detection of Omicron infections in persons with underlying health conditions is needed.

Pediatric influenza vaccination rates lower than previous estimates in the United States. Vaccine 2022; 40:6337-6343. [PMID: 36167694 DOI: 10.1016/j.vaccine.2022.09.053] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Revised: 09/01/2022] [Accepted: 09/17/2022] [Indexed: 01/27/2023]
Abstract
BACKGROUND Annually, pediatric influenza vaccination coverage estimates are ascertained from health surveys, such as the National Immunization Survey (NIS-Flu). From 2010 to 2017, vaccination coverage among children ranged from 51 to 59 %. Recognizing the limitations of national health survey data, we sought to describe temporal trends in pediatric influenza vaccination coverage, and demographic differences among a commercially insured large national cohort from 07/01/2010 to 06/30/2017. METHODS Influenza vaccination coverage was assessed among children (<18 years) with continuous enrollment in the de-identified Optum Clinformatics® Data Mart database, and from NIS-Flu. Time trends in vaccination coverage were assessed using Joinpoint regression, overall and stratified by age group, sex, and geographic region. RESULTS The average annual pediatric influenza vaccination coverage was 33.4 % in our study population versus 56.5 % reported from NIS-Flu during the same period (p-value < 0.0001). Vaccination coverage was highest in children 6 months-4-years old at 52.6 % (versus 68.8 % NIS-Flu, p-value < 0.0001), and lowest in the 13-17-year-old age group at 20.1 % (versus 42.8 % NIS-Flu, p-value < 0.0001). Vaccination coverage over time remained stable in our study population (average annual percent change 1.8 %, 95 % confidence interval [CI] -2.3 % to 6.0 %) versus significantly increasing by 2.8 % in NIS-Flu (95 % CI 0.3 % to 5.3 %). CONCLUSIONS Vaccination coverage in our commercially insured pediatric population was 51.4% lower than estimates from NIS-Flu during the same period, suggesting the need for more accurate vaccination coverage surveillance, which will also be critical in future COVID-19 vaccination efforts. Effective interventions are needed to increase pediatric influenza vaccination rates to the Healthy People 2020 target of 70%.

Abstract
(1) Background: The Vaccine Coverage Rate of influenza remains low and omnichannel efforts are required to improve it. The objective was to evaluate the feasibility and outcomes of a QR Code nudging system in outpatient departments. (2) Methods: The study was performed in 6 departments ensuring ambulatory activities in a French university Hospital between November and December 2021. By scanning QR codes, users accessed anonymously to the ELEFIGHT® web app, which provides medical information on influenza and invites them to initiate a discussion about influenza prevention with their physicians during the consultation. (3) Results: 351 people made 529 scans with an average reading time of 1 min and 4 s and a conversion rate of 32%, i.e., people willing to engage in a discussion. (4) Conclusions: The study suggests that direct access to medical information through QR codes in hospitals might help nudge people to raise their awareness and trigger their action on influenza prevention.

Abstract
Our objective was to determine the influenza vaccination rate in a Spanish cohort of multiple sclerosis (MS) patients. A retrospective cohort study was carried out. Patients who attended the MS unit of the Lozano Blesa Hospital of Zaragoza between January 2015 and 2020 were included. The variables were obtained by reviewing the specialized and primary care records. Associations between receiving the vaccine in each flu season and the other variables were analyzed using bivariate analysis and multiple logistic regression models. A total of 260 patients were studied, with a median age of 31 years at the time of diagnosis. A total of 62.3% (162/260) were women. Vaccination coverage ranged from 20.4% in the 2015−2016 and 2016−2017 seasons to 41.5% in the 2019−2020 season (p = 0.000). Having been vaccinated in the previous season (ORa: 16.47−390.22; p = 0.000) and receiving a vaccination recommendation from the hospital vaccination unit (ORa: 2.44−3.96; p < 0.009) were associated with being vaccinated. The coverage is in an intermediate position compared to other countries. It is necessary to improve the referral system of these patients to the hospital vaccination unit because the information obtained by this service contributed to higher vaccination rates.

Nurses’ Influenza Vaccination and Hesitancy: A Systematic Review of Qualitative Literature. Vaccines (Basel) 2022; 10:vaccines10070997.

Abstract
Vaccine hesitancy (VH) is defined as “delaying or refusing a secure vaccine despite its availability”. This hesitancy affects caregivers and more specifically nurses. The purpose of this study is to assess determinants of influenza VH in the nurse’s community. We conducted a systematic review of qualitative literature according to criteria of Preferred Reporting Items for Systematic Review and Meta-Analysis and Enhancing Transparency in Reporting the synthesis of Qualitative Research from 2009 until October 2020. Eleven qualitative studies analysed (ten thematic content analyses and one grounded theory method) found three main factors in VH. The first determinant was the benefit–risk equation considered as unfavourable due to an ineffective vaccine and fears about adverse effects as the pain of the injection. Wrong immunological beliefs brought into hesitancy. Disease barriers (hand washing and masks) and personal immunity were regarded as more effective than the vaccine. Lastly, dehumanised vaccination and the difficulties of access to healthcare were institutional determinants. Nurses ask for a vaccine promotion by hierarchy and doctors with transparent information and respect for autonomy. The availability of vaccines and methods of pain control seem to be some tracks to reduce nurses’ VH.

Abstract
The selection of a facile, eco-friendly, and effective methodology is the need of the hour for efficient curing of the COVID-19 virus in air, water, and many food products. Recently, semiconductor-based photocatalytic methodologies have provided promising, green, and sustainable approaches to battle against viral activation via the oxidative capabilities of various photocatalysts with excellent performance under moderate conditions and negligible by-products generation as well. Considering this, recent advances in photocatalysis for combating the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are inclusively highlighted. Starting from the origin to the introduction of the coronavirus, the significant potential of photocatalysis against viral prevention and -disinfection is discussed thoroughly. Various photocatalytic material-based systems including metal-oxides, metal-free and advanced 2D materials (MXenes, MOFs and COFs) are systematically examined to understand the mechanistic insights of virus-disinfection in the human body to fight against COVID-19 disease. Also, a roadmap toward sustainable solutions for ongoing COVID-19 contagion is also presented. Finally, the challenges in this field and future perspectives are comprehensively discussed involving the bottlenecks of current photocatalytic systems along with potential recommendations to deal with upcoming pandemic situations in the future.

Abstract
Antigenic characterization of emerging and re-emerging viruses is necessary for the prevention of and response to outbreaks, evaluation of infection mechanisms, understanding of virus evolution, and selection of strains for vaccine development. Primary analytic methods, including enzyme-linked immunosorbent/lectin assays, hemagglutination inhibition, neuraminidase inhibition, micro-neutralization assays, and antigenic cartography, have been widely used in the field of influenza research. These techniques have been improved upon over time for increased analytical capacity, and some have been mobilized for the rapid characterization of the SARS-CoV-2 virus as well as its variants, facilitating the development of highly effective vaccines within 1 year of the initially reported outbreak. While great strides have been made for evaluating the antigenic properties of these viruses, multiple challenges prevent efficient vaccine strain selection and accurate assessment. For influenza, these barriers include the requirement for a large virus quantity to perform the assays, more than what can typically be provided by the clinical samples alone, cell- or egg-adapted mutations that can cause antigenic mismatch between the vaccine strain and circulating viruses, and up to a 6-month duration of vaccine development after vaccine strain selection, which allows viruses to continue evolving with potential for antigenic drift and, thus, antigenic mismatch between the vaccine strain and the emerging epidemic strain. SARS-CoV-2 characterization has faced similar challenges with the additional barrier of the need for facilities with high biosafety levels due to its infectious nature. In this study, we review the primary analytic methods used for antigenic characterization of influenza and SARS-CoV-2 and discuss the barriers of these methods and current developments for addressing these challenges.

The Health Professional's View on the Inclusion of Age in the Recommendations for Pneumococcal Vaccination: Results of a Cross-Sectional Survey in France. Geriatrics (Basel) 2021; 7:geriatrics7010004. [PMID: 35076506 PMCID: PMC8788281 DOI: 10.3390/geriatrics7010004] [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: 11/15/2021] [Revised: 12/17/2021] [Accepted: 12/22/2021] [Indexed: 11/16/2022] Open
Abstract
Elderly people are at high risk for pneumococcal infections. However, older age is not an eligibility factor for pneumococcal vaccination in France. Adults with certain co-morbidities or immunocompromised states are eligible for vaccination, which leaves adults aged ≥65 years without comorbidities at-risk for pneumococcal infections. The objective of the study was to evaluate the acceptability to healthcare professionals (HCPs) of extending pneumococcal vaccination to all individuals ≥65 years. Based on themes identified in semi-structured interviews with 24 HCPs, a representative sample of 500 general practitioners and pharmacists were surveyed about their knowledge, attitudes and beliefs with respect to pneumococcal vaccination for individuals ≥65 years. Current recommendations for pneumococcal vaccination are poorly understood by participants (mean score: 5.8/10). Respondents were generally supportive of inclusion of age in vaccination recommendations (7.5/10), with 58% being very supportive. For 72% of HCPs, this would contribute to improved vaccination coverage. The strategy could be facilitated by associating pneumococcal vaccination with the influenza vaccination campaign (8.3/10). Pharmacists were favourable to participating in pneumococcal vaccination (8.5/10). In conclusion, extension of pneumococcal vaccination to all people aged ≥65 years would be welcomed by HCPs, simplifying identification of patients to be vaccinated and potentially improving vaccination coverage.

Abstract
INTRODUCTION The objective of our study was to assess, in an at-risk population, perception and knowledge about influenza and pneumococcal vaccinations. METHODS An anonymous web-based survey was submitted to patients recruited in France, from both an Ipsos internal panel and AVNIR patient associations. The study was conducted between July and October 2020, in the context of the COVID-19 pandemic. RESULTS Overall, 2177 questionnaires from patients at risk of infection were analyzed. Almost all respondents (86%, 1869/2177) declared themselves to be favorable to vaccination. Nearly half of the patients (49%, 1069/2177) were aware of which vaccine was recommended for their specific situation. This percentage was significantly (p < 0.001) higher for members of a patient association and for people affected by multiple chronic conditions and varied according to the type of condition. Almost two-thirds of patients (1373/2177) declared having been vaccinated during the 2019/2020 influenza season, and 41% (894/2177) were certain about being up to date with the pneumococcal vaccination. The main barriers to vaccination for influenza are the fear of side effects, doubt regarding the efficacy of the vaccine and for pneumococcal vaccination, and the absence of suggestions by the healthcare professionals (HCPs), as 64% of respondents were not recommended to obtain pneumococcal vaccination. To improve vaccine coverage, information is of prime importance and GPs are recognized as the main HCP to inform about vaccination. Nearly two-thirds (62%, 1360/2177) of patients declared that the COVID-19 pandemic convinced them to have all the recommended vaccines. CONCLUSION Our study highlighted the nonoptimal vaccine coverage in at-risk populations despite a highly positive perception of vaccines and confirmed that physicians are on the front lines to suggest and recommend these vaccinations, especially in the current pandemic context, which may be used to promote other vaccines.

Abstract
BACKGROUND Antibiotic consumption has been reported to be driven by the treatment of respiratory tract infections. Our objectives were to describe the trend of antibiotic consumption in France compared with that of other European countries; to describe the evolution of each antibiotic class in France; and to explore the relationship between antibiotic consumption and incidence of influenza-like illnesses. METHODS In this observational study, antibiotic consumption was reported as defined daily doses per 1000 inhabitants per day in the community and hospital sectors in descriptive and graphical formats, using data from the European Surveillance of Antimicrobial Consumption Network database. The total consumption and the consumption of different classes of antibiotics in France according to time and influenza-like illnesses were studied using multiple linear regression models. RESULTS The total consumption of antibiotics in France was constant over the 15 years. It was driven by the community sector (92.8%) and was higher than the consumption of other European Union countries (P-value < 0.001). The beta-lactam penicillins were the most consumed antibiotic class and the only class that increased with time. The multiple linear regression models showed a positive correlation between antibiotic consumption in the community sector and incidence of influenza-like illnesses [B = 0.170, 95% CI (0.088-0.252)]. Similar significant results were shown between other antibiotic classes used in the management of influenza-like illnesses (other beta-lactams, and macrolides, lincosamides and streptogramins) and influenza-like illnesses. CONCLUSION Our results suggest that antibiotics used in the management of respiratory tract infections might be involved in the irrational use of antibiotics.

Abstract
We aimed to assess the impact of the Covid-19 pandemic on the risk perception and attitudes concerning influenza and pneumococcal vaccination in an at-risk population. We performed an online survey between July 29th and October 12th 2020 in patients at risk of severe influenza and/or pneumococcal disease recruited from Ipsos internal panel or through AVNIR (Associations VacciNation Immunodéprimées Réalité), a group of patient associations. Among the 2177 respondents, 1350 were female (62%), median age was 58 years (IQR 47-69), 62% were immunocompromised. In total, 86% of respondents declared being favorable to vaccination in general and felt at high-risk of more severe forms of Covid-19 (81%), pneumococcal disease (76%) and influenza (74%). More than half (52%, 388/746) of patients were eager to be vaccinated annually against influenza for the next 2020/2021 season and pneumococcal disease in the future: 62% (376/606). In this sample of patients at-risk of severe forms of influenza, pneumococcal diseases and Covid-19, the self-perception of risk for these three diseases and positive opinion on vaccination in general were high. It is very likely that the pandemic will lead to an increase in influenza and pneumococcal vaccine coverage in this at-risk population.

Abstract
Influenza remains a major cause of illness and death in geriatric populations. While the influenza vaccine has successfully reduced morbidity and mortality, its effectiveness is suspected to decrease with age. The aim of this study was to assess the impact of influenza vaccination on all-cause mortality in very old ambulatory subjects. We conducted a prospective cohort study from 1 July 2016 to 31 June 2017 in a large unselected ambulatory population aged over 80 years. We compared all-cause mortality in vaccinated versus unvaccinated subjects after propensity-score matching, to control for age, sex and comorbidities. Among the 9149 patients included, with mean age 86 years, 4380 (47.9%) were vaccinated against influenza. In total, 5253 (57.4%) had at least one chronic disease. The most commonly vaccinated patients were those with chronic respiratory failure (76.3%) and the least commonly vaccinated were those suffering from Parkinson’s disease (28.5%). Overall, 2084 patients (22.8%) died during the study. After propensity score matching, the mortality was evaluated at 20.9% in the vaccinated group and 23.9% in the unvaccinated group (OR = 0.84 [0.75–0.93], p = 0.001). This decrease in mortality in the vaccinated group persisted whatever the age and Charlson Comorbidity index. In conclusion, nearly a half of this ambulatory elderly population received Influenza vaccine. After adjustment on comorbidities, influenza vaccination was associated with a significant decrease in all-cause mortality, even in the eldest multimorbid population. Improving immunization coverage in this frail older population is urgently needed.
