Seasonal influenza is of the most globally burdening vaccine-preventable diseases, infecting 3-5 billion people annually and according to the World Health Organisation (WHO) resulting in 250,000 to 500,000 deaths worldwide. Vaccination against influenza and all respiratory infections carries greater emphasis in the light of the COVID-19 pandemic. With added pressure on healthcare systems due to the coronavirus, Qatar is one country that is keen to emphasise the importance of influenza vaccination to prevent potential co-infection causing severe disease especially in high-risk groups. Currently seasonal influenza vaccines protect against 3 or 4 strains with revised data from the WHO twice yearly due to the changing natures of strains helping to maximise efficacy of the vaccines. It is recommended for specific high-risk groups to be prioritised for vaccination, including pregnant women, the elderly, children above 6 months of age, patients with chronic conditions as well as front line healthcare workers with risk of exposure. However, uptake of the vaccine remains low and contributes significantly to the burden of the disease. Barriers to vaccine uptake can be physical, such as unhealthy lifestyles, psychological, such as perception of disease as low-risk, contextual, such as lack of access to vaccinations, or sociodemographic, such as living alone. Vaccine coverage can be increased by knowledge of these barriers and how to address them. The physical barriers highlight the need to support behavioural change in lifestyle in order to increase vaccine uptake. Psychological barriers, usually due to misconceptions, can be addressed with education through public health campaigns and interactions between health professionals and patients. This education is not just a need for patients but also healthcare workers. It is up to healthcare providers and contractors to find ways of addressing contextual and sociodemographic barriers by increasing access to vaccination whether through transport, or home–care etc. A key barrier of those mentioned to vaccination is a lack of knowledge which needs to be addressed though positive discussions about the health benefits of immunisation as well as the traditional idea of disease-risk prevention. Addressing the above barriers will help to increase vaccine uptake, and produce health-conscientious societies where vaccination becomes a social norm.

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.

The Impact

Abstract Background All aged individuals with a chronic condition and those with 65 and more years are at increased risk of severe influenza post-infection complications. There is limited research on cases averted by the yearly vaccination programs in high-risk individuals. The objective was to estimate the impact of trivalent seasonal influenza vaccination on averted hospitalizations and death among the high-risk population in Portugal. Methods The impact of trivalent seasonal influenza vaccination was estimated using vaccine coverage, vaccine effectiveness and the number of influenza-related hospitalizations and deaths. The number of averted events (NAE), prevented fraction (PF) and number needed to vaccinate (NVN) were estimated for seasons 2014/15 to 2016/17. Results The vaccination strategy averted on average approximately 1833 hospitalizations and 383 deaths per season. Highest NAE was observed in the ≥65 years population (85% of hospitalizations and 95% deaths) and in the 2016/17 season (1957 hospitalizations and 439 deaths). On average, seasonal vaccination prevented 21% of hospitalizations in the population aged 65 and more, and 18.5% in the population with chronic conditions. The vaccination also prevented 29% and 19.5% of deaths in each group of the high-risk population. It would be needed to vaccinate 3360 high-risk individuals, to prevent one hospitalization and 60,471 high-risk individuals to prevent one death. Conclusion The yearly influenza vaccination campaigns had a sustained positive benefit for the high-risk population, reducing hospitalizations and deaths. These results can support public health plans toward increased vaccine coverage in high-risk groups.

Background: Seasonal influenza infections are a major cause of morbidity and mortality worldwide. Healthcare workers (HCWs) are an important target group for vaccination against influenza due to their increased risk of infection and their potential to transmit the infection to their patients, families and communities. The aim of this study was to assess the potential hesitancy and its associated factors towards influenza vaccination amongst HCWs in the South Al Batinah governorate in Oman. Methods: A cross-sectional survey of 390 HCWs with direct or indirect patient contact was conducted in May and June 2019 using a self-administered questionnaire. Associations between HCW characteristics and vaccination status were examined using bivariate and multivariate analyses to identify the likelihood of vaccination against seasonal influenza among HCWs. Results: Overall, 60% of HCWs were vaccinated in the 2018/2019 season; vaccine uptake among nurses was 52% and uptake was higher among women. Self-protection and protection of the community were the most cited reasons for vaccine acceptance, with side effects being the main reason for hesitancy. Vaccinated respondents had a higher mean knowledge score (7.18; standard deviation SD: 2.14) than unvaccinated respondents (6.30; SD: 2.2). Odds of vaccination were highest among respondents who believed influenza vaccine should be mandatory for HCWs (Odds ratio (OR): 2.04 [1.30–3.18]), those working in the general medicine, emergency medicine, or intensive care units (OR: 1.92 [1.20–3.10]), nurses and doctors (OR: 1.75 [1.09–2.79]) and those who believe that HCWs should receive an influenza vaccine (OR: 1.35 [1.07–2.77]). Conclusions: The study provides valuable insights into the enablers and barriers of influenza vaccination practices among HCWs and may inform interventions to increase acceptance of vaccination.

The Impact

Since 2008, annual surveys of influenza vaccination policies, practices and coverage have been undertaken in 29 European Union (EU)/ European Economic Area (EEA) countries. After 2009, this monitored the impact of European Council recommendation to increase vaccination coverage to 75% among risk groups. This paper summarises the results of three seasonal influenza seasons: 2008/09, 2009/10 and 2010/11. In 2008/09, 27/29 countries completed the survey; in 2009/10 and 2010/11, 28/29 completed it. All or almost all countries recommended vaccination of older people (defined as those aged ≥50, ≥55, ≥59, ≥60 or ≥65 years), and people aged ≥6 months with clinical risk and healthcare workers. A total of 23 countries provided vaccination coverage data for older people, but only 7 and 10 had data for the clinical risk groups and healthcare workers, respectively. The number of countries recommending vaccination for some or all pregnant women increased from 10 in 2008/09 to 22 in 2010/11. Only three countries could report coverage among pregnant women. Seasonal influenza vaccination coverage during and after the pandemic season in older people and clinical groups remained unchanged in countries with higher coverage. However, small decreases were seen in most countries during this period. The results of the surveys indicate that most EU/EEA countries recommend influenza vaccination for the main target groups; however, only a few countries have achieved the target of 75% coverage among risk groups. Coverage among healthcare workers remained low.

Vaccine Shortages

AbstractInfluenza causes substantial morbidity and mortality annually, particularly in high-risk groups such as the elderly, young children, immunosuppressed individuals, and individuals with chronic illnesses. Healthcare-associated transmission of influenza contributes to this burden but is often under-recognized except in the setting of large outbreaks. The Centers for Disease Control and Prevention has recommended annual influenza vaccination for healthcare workers (HCWs) with direct patient contact since 1984 and for all HCWs since 1993. The rationale for these recommendations is to reduce the chance that HCWs serve as vectors for healthcare-associated influenza due to their close contact with high-risk patients and to enhance both HCW and patient safety. Despite these recommendations as well as the effectiveness of interventions designed to increase HCW vaccination rates, the percentage of HCWs vaccinated annually remains unacceptably low. Ironically, at the same time that campaigns have sought to increase HCW vaccination rates, vaccine shortages, such as the shortage during the 2004-2005 influenza season, present challenges regarding allocation of available vaccine supplies to both patients and HCWs. This two-part document outlines the position of the Society for Healthcare Epidemiology of America on influenza vaccination for HCWs and provides guidance for the allocation of influenza vaccine to HCWs during a vaccine shortage based on influenza transmission routes and the essential need for a practical and adaptive strategy for allocation. These recommendations apply to all types of healthcare facilities, including acute care hospitals, long-term-care facilities, and ambulatory care settings.

Vaccine Uptake

Influenza vaccination coverage was low among healthcare workers (HCWs) in China. In October 2018, the National Health Commission of China began to require all hospitals to provide free influenza vaccination for HCWs to increase vaccine uptake, and no study on vaccine coverage among HCWs at the national level after the announcement of new policy. This evaluation aims to investigate self-reported influenza vaccination coverage among HCWs and factors that may affect vaccine receipt during the 2018/2019 influenza season. We delivered an opt-in internet panel survey among registered HCWs of DXY forum (the biggest online forum for HCWs in China). The survey was self-administered using a standard questionnaire to collect information on demographics, occupational characteristics, policy implementation, influenza vaccination and influence factors. We conducted multivariate logistic regression analysis to assess factors associated with receipt of influenza vaccine. The response rate of this online survey was 3.6%. The seasonal influenza vaccine coverage reported among HCWs surveyed during the 2018/2019 season was 11.6% (472/4078). Only 19.0% (774/4078) of HCWs surveyed reported free policy in their workplace. Combing free policy and workplace requirement proved to be effective to improve influenza vaccination coverage in HCWs (PR = 6.90, 95% CI: 6.03–7.65). The influenza vaccination coverage among surveyed HCWs in China was low during the 2018/2019 season. To increase future vaccination uptake, we recommend a multi-faceted strategy that include free policy, workplace requirement and promotion, on-site vaccination, and monitoring.

Vaccine Distribution

Seasonal influenza is widely regarded as a continuing threat to public health, with vaccination remaining the principal measure of prophylaxis. In 2003, the World Health Organization issued targets for influenza vaccine coverage in the elderly of at least 50% by 2006 and 75% by 2010, endorsed by the European Parliament in two resolutions in 2005 and 2006. However, a number of European public health systems lack mechanisms to assess progress in influenza vaccine uptake. The European Vaccine Manufacturers group (EVM) undertook a Europe-wide survey of vaccine distribution over the last five seasons (between 2003 and 2008) to provide baseline data from which vaccination trends may be extrapolated. The survey data showed that the dose distribution level per capita in the 27 EU countries increased from 17% in 2003-4 to 20% in 2006-7; this growth was not maintained in the season 2007-8. Even without information on which age or risk groups received the vaccine, an immunisation rate of approximately 20% of the whole population falls short of the public health goal by more than half: an estimated 49% of the total population fall into risk groups recommended to receive the influenza vaccine in Europe. These data provide the only systematic review of vaccine dose distribution across Europe from a uniform source. Although they represent an important baseline parameter, age- and risk-group related vaccine uptake data with sufficient detail are needed to assist public health policy decision making, immunisation planning and monitoring. In light of this situation, and to support the improvement of immunisation rates across the EU, EVM aims to provide dose distribution data for each influenza season to assist Member States in the implementation of local immunisation policies.

Background: Influenza can cause severe illness among high-risk groups such as elderly and immunocompromised patients. Mandatory influenza vaccination of healthcare workers (HCWs) has been viewed as means to improve patient and HCW protection. Methods: We analyzed data collected by a web-based survey sent annually to all Finnish acute care hospitals and described the influenza vaccination coverage among HCWs during seasons 2017/18 (without mandate) and 2018/19 (mandate enforced). Results: In season 2017/2018, 38/39 hospitals provided data and 35/36 hospitals in 2018/2019. The mean coverage in season 2017/18 was 88% (median, 84%; range 48-100%) and in 2018/19 91% (median, 91%; range 57-100%). The mean increase from season 2017/2018 to 2018/2019 was 6.5% (median, 3%; range -11.0-33.0%). Conclusions: The coverage of influenza vaccinated HCWs in Finnish hospitals was high. However, there were major differences between hospitals which raise the question about data quality as well as implementation of the mandate, and need further evaluation.

Negative Effect

Controversies over the effectiveness and safety of the pandemic influenza A(H1N1)pdm09 vaccine in 2009/10 may have altered the influenza vaccination coverage in France after the pandemic season. The purpose of this study was to determine whether the pandemic affected seasonal influenza vaccination behaviours in the general population by analysing vaccination behaviours from 2006/07 to 2011/12 among the 1,451 subjects of the Cohort for Pandemic Influenza (CoPanFlu) France. We found that vaccination behaviours in 2010/11 and 2011/12 significantly differed from behaviours before the pandemic, with the notable exception of the targeted risk groups for seasonal influenza-related complications. Among the population with no risk factors, the post-pandemic influenza vaccine coverage decreased, with people aged 15 to 24 years and 45 to 64 years being most likely to abandon vaccination. Therefore, this study documents a moderate negative effect of the 2009/10 pandemic episode on vaccination behaviours in the French metropolitan population that was apparent also in the following two seasons. Moreover, it does not exclude that the general trend of reduced vaccination has also affected certain targeted groups at high risk for complications.
