Annually, at a global level, 3 to 5 million people present severe clinical forms of seasonal influenza and up to 650 000 people die of influenza-related complications. People with chronic diseases, such as cardiovascular, pulmonary, renal, hepatic, neurologic, hematologic and metabolic diseases or those reciveing immunosuppressive therapy, constitute a high-risk population group for the development of influenza-related complications, more severe clinical course and poorer health-related outcomes. Due to all of the above, people with chronic diseases are of high priority to receive the influenza vaccine. Immunization represents the key strategy to prevent influenza both in terms of effectiveness and health care costs. Based on the World Health Organization (WHO) recommendations, adequate seasonal influenza immunization coverage among people with chronic diseases is set at 75%. However, few countries achieve this threshold. Understanding predictive factors of vaccination, at different levels of health care delivery (such as individuals, service providers, health policy), is essential to secure acceptance of influenza immunization and achieve the recommended level of vaccination coverage. In this mini review, all the available evidence regarding seasonal influenza vaccination coverage is summarized, alongside factors associated with vaccine uptake in people with chronic diseases as a whole, as well as according to specific diseases such as: cardiovascular and pulmonary disorders, diabetes and cancer. Based on the reviewed empirical evidence, a wide spectrum of factors associated with immunization against influneza was found in people who have chronic diseases. Although diverse, these factors can be systematized into 4 distinctive groups: socio-demographic characteristics, individual attitudes and beliefs, health promoting behaviors and factors related to the health care system. Further efforts are needed to improve the seasonal influenza vaccination coverage. The immunization strategy needs to include the health care system and the community to support people with chronic diseases to continously accept the influenza vaccine.

Abstract Background Given the nature of their activities, health care workers (hcws) are at higher risk of contracting influenza and transmitting the disease to their patients. Influenza vaccine (IV) remains the most effective way to prevent influenza and its complications. To the best of our knowledge, no national data on IV coverage among hcws is available in Tunisia. The present study aimed to assess the flu vaccination coverage among Tunisian hcws in the 2018-2019 influenza season and factors associated with IV uptake through a study of knowledge and attitudes related to influenza vaccination. Methods A cross sectional study was conducted in Tunisian primary and secondary health care facilities from March to May 2019. Hcws with direct patient contact were recruited according to a self-weighted multistage sampling. Survey data collection was based on a face to face questionnaire containing both open and closed questions. Results A total of 1231 hcws were enrolled in this study. Among respondents, 15.3% (95% CI: [12.3-17.2]) were vaccinated against influenza during the 2018-2019 influenza season. High confidence regarding vaccine efficacy (OR = 3.5, 95%CI: 2.5-4.8), belief that hcws' influenza immunization may decrease illness and deaths among patients (OR = 1.7, 95% CI: 1.2-2.3) and belief that influenza vaccination can reduce work absenteeism (OR = 1.7, 95% CI: 1.2-2.4) were associated with a higher IV uptake among hcws. In addition, participants who mentioned hcws as a target group for influenza vaccination (OR = 2.0, 95% CI: 1.5-2.8) and who were agree that IV is indicated annually for hcws (OR = 3.1, 95% CI: 1.9-4.9) were more likely to receive the IV. Conclusions Influenza vaccination coverage among Tunisian health professionals in 2018-2019 was low. Our findings suggest that knowledge and attitudes regarding influenza vaccine influence vaccine compliance among hcws and should thus be targeted by vaccination campaigns to promote flu vaccine uptake in the health community. Key messages Vaccination coverage among Tunisian healthcare workers was low in the 2018-2019 influenza season. Our findings suggest that knowledge and attitudes regarding influenza vaccine influence vaccine uptake among Tunisian health care workers.

Background Influenza during pregnancy may cause serious neonatal outcomes including stillbirth, fetal distress, preterm birth, congenital abnormalities, and stunted growth. Pregnant women are the highest priority group for seasonal influenza vaccination, but low coverage has been repeatedly reported in this population. Understanding reasons for and for not receiving the seasonal influenza vaccine is needed to design communication strategies to increase vaccination coverage. This study aimed to describe knowledge, attitudes, and practices (KAP) of seasonal influenza vaccination among women giving birth in public maternity hospitals in Honduras. Methods From August 20–October 8, 2018, we conducted a cross-sectional KAP survey regarding seasonal influenza vaccinations to a sample of postpartum women who gave birth in maternity hospitals and clinics from the Ministry of Health of Honduras and Honduran Social Security Institute. We reported frequency distributions for demographics, KAP of influenza vaccine, and vaccination coverage. We used logistic regression to analyze unadjusted and adjusted associations between sociodemographic characteristics and influenza vaccination. Results We surveyed 842 postpartum women in 17 healthcare facilities. Of 534 postpartum women with term pregnancy and verified vaccinations, 417 (78.1%; 95% CI: 74.6–81.6%) were vaccinated for influenza. Factors associated with verified influenza vaccination included receipt of vaccination recommendations by a healthcare worker during prenatal check-ups (aOR: 16.46; 95% CI: 9.73–27.85), concurrent chronic disease (aOR: 5.00; 95% CI: 1.25–20.07), and influenza vaccination of other children in the household (aOR: 2.28; 95% CI: 1.19–4.39). The most cited reasons for vaccination were perceived benefits for both mother and infant and easy access. Reasons for non-vaccination were: vaccine was not offered and fear of side effects, harm to the infant, and needles or pain caused by injection. Conclusion Influenza vaccination was well received among postpartum women in Honduras. Increasing clinician recommendations for vaccination and assuring the vaccine is readily available to women during prenatal visits may increase vaccination rates.

Abstract Background Influenza is a major public health issue, with the primary preventive measure being an annual influenza vaccination. Nevertheless, vaccination coverage among the at-risk population is low. Our understanding of the behaviour of the influenza virus during the SARS-CoV-2 coronavirus pandemic is limited, meaning influenza vaccination is still recommended for individuals at risk for severe complications due to influenza infection. The aim of the study is to determine the intention to vaccinate against seasonal influenza among the at-risk population in the 2020-21 campaign during the SARS-CoV-2 pandemic and to analyse the factors which influence such intention. Methods Cross-sectional telephone survey of adults (aged over 18) with risk factors in central Catalonia where the need for the Seasonal Influenza Vaccine (SIV) was recommended. Results A total of 434 participants responded to the survey, 43.3% of whom intended to be vaccinated against influenza for the 2020-2021 influenza season, 40.8% had no intention to be vaccinated and 15.9% were uncertain or did not express their opinion. The intention to get vaccinated against influenza is associated with having dependents, the individual’s perception of the risk of being infected with influenza and the perceived risk of transmission to dependents. It is also associated with age, whether the individual had received influenza vaccine the previous season or any other season before. The best predictors of the intention to vaccinate are the individual’s perception of the risk of catching influenza and whether the individual had been vaccinated in the previous season. Conclusions Intention to vaccinate can be a good predictor of individual behaviour in relation to vaccination. During the current SARS-CoV-2 pandemic many individuals are hesitant to influenza vaccination. In order to improve influenza vaccination coverage in people included in risk groups, it is necessary to promote educational actions, especially among those who express doubts.

Introduction: Seasonal influenza vaccination is recommended for pregnant women, but half of the pregnant women in the United States remain unvaccinated. Vaccine coverage in U.S.–Mexico border states has not been examined in depth even though risk factors for low vaccine coverage exist in these states, especially in the counties bordering Mexico. Method: Using 2012-2014 New Mexico (NM) Pregnancy Risk Assessment and Monitoring System data, this study examined the weighted annual seasonal influenza vaccination rates and the relationship of various factors to vaccination among NM residents with a live birth during those years. Results: Among respondents, 53.8% were Hispanic, 15.7% were Native American, and 30.5% were non-Hispanic White. The vaccination rate in NM increased from 49.0% in 2012 to 64.8% in 2014. The adjusted odds of vaccination were higher among women whose health care provider recommended/offered vaccination during the year prior to delivery compared to women whose provider did not (AOR = 11.92, 95% confidence interval [CI: 9.86, 14.42]) and among those living in the U.S.–Mexico nonborder counties compared to those living in the border counties (AOR = 1.23, 95% CI [1.18, 1.25]). Conclusion: Efforts to increase the vaccination rate among pregnant women in border states should concentrate on health care providers and the highest risk women, such as those resident in the border region.

Abstract Background Seasonal influenza vaccination (SIV) of health care workers (HCWs) is well recognized as a public health measure that can protect both HCWs from infection and patients from the risk of influenza complications. Nevertheless, vaccination coverage rates among this specific population result generally lower than the recommended target. With our study, we aimed to describe the activities and the outcomes of four different SIV campaigns targeted at HCWs and organized during the season 2018/2019 in four hospitals in Rome. Methods A cross-sectional study involving four teaching hospitals was performed. The collected data were synthetized into a set of descriptors and indicators, validated through a previous study that had involved the same Centers. Results The Medical Directorates, in collaboration with the University Hygiene and Public Health Units of the four hospitals organized different strategies: Hospital 1, 3 and 4 realized educational courses for HCWs and actively promoted the campaigns through e-mail invitations to all HCWs. As for the access to vaccination, all the hospitals provided a dedicated unit for SIV; Hospital 1 and Hospital 4 organized also on-site vaccination sessions in the hospital wards, that required a large number of staff. The vaccination coverage rates resulted: 22.37% in Hospital 1, 18.10% in Hospital 4, 9.28% in Hospital 2 and 8,51% in Hospital 3. Conclusions Our results demonstrate that multi-activity campaigns, involving education, promotion and easy access to vaccination constitute an effective approach to reinforce the value of SIV. Our findings suggest that on-site vaccination may play a key role in determining a higher vaccination coverage. Key messages Multi-activity vaccination campaigns, involving education, promotion and easy access to vaccination constitute an effective approach to reinforce the value of seasonal influenza vaccination for HCWs. On-site vaccination may play a key role in determining a higher vaccination coverage.
