Project description:ObjectivesWhile many countries have robust child immunization programs and high child vaccination coverage, vaccination of adults has received less attention. The objective of this study was to describe the adult vaccination policies in developed countries.MethodsFrom 2010 to 2011, we conducted a survey of 33 advanced economies as defined by the International Monetary Fund. The survey asked about national recommendations for adults for 16 vaccines or vaccine components, funding mechanisms for recommended adult vaccines, and the availability of adult vaccination coverage estimates.ResultsThirty-one of 33 (93.9 %) advanced economies responded to the survey. Twelve of 31 (38.7 %) reported having a comprehensive adult immunization schedule. The total number of vaccines or vaccine components recommended for adults ranged from one to 15 with a median of 10. Seasonal influenza (n = 30), tetanus (n = 28), pneumococcal polysaccharide (n = 27), and hepatitis B (n = 27) were the most frequently recommended vaccines or components.ConclusionsApproximately two-thirds of survey respondents do not have a comprehensive adult vaccine schedule, and most do not measure vaccination coverage. We found that a funding mechanism is available for most recommended adult vaccines.

Project description:BACKGROUND: While immunization is one of the most effective and successful public health interventions, there are still up to 30,000 deaths in major developed economies each year due to vaccine-preventable diseases, almost all in adults. In the UK, despite comparatively high vaccination rates among ≥65 s (73%) and, to a lesser extent, at-risk ≤65 s (52%) in 2013/2014, over 10,000 excess deaths were reported the previous influenza season. Adult tetanus vaccines are not routinely recommended in the UK, but may be overly administered. Social influences and risk-perceptions of diseases and vaccines are known to affect vaccine uptake. We aimed to explore the socio-psychological factors that drive adult vaccination in the UK, specifically influenza and tetanus, and to evaluate whether these factors are comparable between vaccines. METHODS: 20 in-depth, face-to-face interviews were conducted with members of the UK public who represented a range of socio-demographic characteristics associated with vaccination uptake. We employed qualitative interviewing approaches to reach a comprehensive understanding of the factors influencing adult vaccination decisions. Thematic analysis was used to analyze the data. RESULTS: Participants were classified according to their vaccination status as regular, intermittent and non-vaccinators for influenza, and preventative, injury-led, mixed (both preventative and injury-led) and as non-vaccinators for tetanus. We present our finding around five overarching themes: 1) perceived health and health behaviors; 2) knowledge; 3) vaccination influences; 4) disease appraisal; and 5) vaccination appraisal. CONCLUSION: The uptake of influenza and tetanus vaccines was largely driven by participants' risk perception of these diseases. The tetanus vaccine is perceived as safe and sufficiently tested, whereas the changing composition of the influenza vaccine is a cause of uncertainty and distrust. To maximize the public health impact of adult vaccines, policy should be better translated into high vaccination rates through evidence-based implementation approaches.

Project description:In the wake of the Portuguese vaccination program 50th anniversary it seems appropriate to review vaccination in patients with systemic lupus erythematosus. Controversial issues as regards the association between autoimmune diseases, infections, and vaccines are discussed as well as vaccine safety and efficacy issues as regards chronic immunosuppressant (IS) drug therapy. After a brief overview of national policies, specific recommendations are made as regards vaccination for adult patients with SLE with a particular focus on current IS therapy and unmet needs.

Project description:Vaccine-preventable deaths among adults remain a major public health concern, despite continued efforts to increase vaccination rates in this population. Alternative approaches to immunization delivery may help address under-vaccination among adults. This systematic review assesses the feasibility, acceptability, and effectiveness of community pharmacies as sites for adult vaccination. We searched 5 electronic databases (PubMed, EMBASE, Scopus, Cochrane, LILACS) for studies published prior to June 2016 and identified 47 relevant articles. We found that pharmacy-based immunization services (PBIS) have been facilitated by state regulatory changes and training programs that allow pharmacists to directly provide vaccinations. These services are widely accepted by both patients and pharmacy staff, and are capable of improving access and increasing vaccination rates. However, political and organizational barriers limit the feasibility and effectiveness of vaccine delivery in pharmacies. These studies provide evidence to inform policy and organizational efforts that promote the efficacy and sustainability of PBIS.

Project description:Despite vast improvements in childhood vaccination coverage in India, adult vaccination coverage is negligible. Our aim was, therefore, to create awareness about the importance of adult immunization. Although the true burden of vaccine-preventable diseases (VPDs) among Indian adults is unknown, adults are particularly vulnerable during outbreaks, due to a lack of immunization, waning immunity, age-related factors (e.g. chronic conditions and immunosenescence), and epidemiological shift. There are no national adult immunization guidelines in India, and although several medical societies have published adult immunization guidelines, these vary, making it unclear who should receive which vaccines (based on age, underlying conditions, etc.). Other barriers to adult immunization include vaccine hesitancy, missed opportunities, and cost. Steps to improve adult vaccination could include: adoption of national guidelines, education of healthcare providers and the public, and promotion of life-course immunization. Improving adult vaccine coverage could help reduce the burden of VPDs, particularly among older adults.

Project description:Influenza vaccination remains below the federally targeted levels outlined in Healthy People 2020. Compared to non-Hispanic whites, racial and ethnic minorities are less likely to be vaccinated for influenza, despite being at increased risk for influenza-related complications and death. Also, vaccinated minorities are more likely to receive influenza vaccinations in office-based settings and less likely to use non-medical vaccination locations compared to non-Hispanic white vaccine users.To assess the number of "missed opportunities" for influenza vaccination in office-based settings by race and ethnicity and the magnitude of potential vaccine uptake and reductions in racial and ethnic disparities in influenza vaccination if these "missed opportunities" were eliminated.National cross-sectional Internet survey administered between March 4 and March 14, 2010 in the United States.Non-Hispanic black, Hispanic and non-Hispanic white adults living in the United States (N?=?3,418).We collected data on influenza vaccination, frequency and timing of healthcare visits, and self-reported compliance with a potential provider recommendation for vaccination during the 2009-2010 influenza season. "Missed opportunities" for seasonal influenza vaccination in office-based settings were defined as the number of unvaccinated respondents who reported at least one healthcare visit in the Fall and Winter of 2009-2010 and indicated their willingness to get vaccinated if a healthcare provider strongly recommended it. "Potential vaccine uptake" was defined as the sum of actual vaccine uptake and "missed opportunities."The frequency of "missed opportunities" for influenza vaccination in office-based settings was significantly higher among racial and ethnic minorities than non-Hispanic whites. Eliminating these "missed opportunities" could have cut racial and ethnic disparities in influenza vaccination by roughly one half.Improved office-based practices regarding influenza vaccination could significantly impact Healthy People 2020 goals by increasing influenza vaccine uptake and reducing corresponding racial and ethnic disparities.

Project description:BackgroundIn recent years, Canadian health care professionals have observed an increase in vaccine refusal. The objective of this study is to review published literature and identify the main themes related to vaccine hesitancy and barriers to vaccination in Canadian adults and recent immigrants.MethodsA qualitative systematic review was performed. A comprehensive search of MEDLINE (1946 to January 2021) and EMBASE (1974 to January 2021) was conducted to identify existing literature that addressed the primary research question. Studies were eligible for inclusion if the study population involved 1) the general population, 2) Indigenous populations, 3) recent immigrants to Canada or 4) Canadian health care professionals.ResultsThirty-four studies were included with a focus on the general population (n = 22), health care professionals (n = 10) and recent immigrant populations (n = 2). The most frequently reported barriers were lack of vaccine information (41%), lack of access to vaccination (38%), fear of adverse reactions (38%), financial reasons (29%), lack of awareness of vaccine existence (29%), antivaccine sentiments (24%), notion that older adults do not need vaccination (18%), misconceptions on vaccine effectiveness (12%), potential sexual health promotion stigma (6%) and fear of needles (3%).InterpretationBarriers to vaccination among Canadians and recent immigrants continue to be a challenge in the health care system.ConclusionsThe greatest yield in improving vaccination rates is likely to come from supporting vaccine-hesitant individuals in shifting their thinking to greater vaccine acceptance. Pharmacists are well positioned to address vaccine hesitancy and involvement through education, facilitation and administration of vaccines. Can Pharm J (Ott) 2022;155:xx-xx.

Project description:BACKGROUND:Pneumococcal disease causes substantial morbidity and mortality, including among adults. Adult pneumococcal vaccines help to prevent these burdens, but they are underused. Accounting for the full benefits of adult pneumococcal vaccination may promote more rational resource allocation decisions with respect to adult pneumococcal vaccines. OBJECTIVES:Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a systematic review to assess the extent to which the literature has empirically captured (e.g., through measurement or modeling) the full benefits of adult pneumococcal vaccination. METHODS:We systematically searched PubMed and Embase to identify studies published between January 1, 2010 and April 10, 2016 that examine adult pneumococcal vaccination. We included articles if they captured any health or economic benefit of an adult pneumococcal vaccine administered to adults age ≥ 50 or ≥ 18 in risk groups. Finally, we summarized the literature by categorizing the types of benefits captured, the perspective taken, and the strength of the evidence presented. Our protocol is number 42016038335 in the PROSPERO International prospective register of systematic reviews. RESULTS:We identified 5,857 papers and included 150 studies for analysis. While most capture health gains and healthcare cost savings, far fewer studies consider additional benefit categories, such as productivity gains. However, the studies with a broader approach still exhibit significant limitations; for example, many present only abstracts, while others offer no new measurements. Studies that examine the 13-valent pneumococcal conjugate vaccine focus more on broad economic benefits, but still have limitations. CONCLUSIONS:This review highlights the need for more robust empirical accounting of the full benefits of adult pneumococcal vaccination. Literature outside this realm indicates that these broad benefits may be substantial. Failing to investigate the full benefits may lead society to undervalue vaccines' contributions and therefore underinvest in their development and adoption.

Project description:INTRODUCTION:Influenza is a major cause of morbidity and mortality among adults. The most effective strategy for preventing influenza is annual vaccination. However, vaccination coverage has been suboptimal among adult populations. The purpose of this study is to assess trends in influenza vaccination among adult populations. METHODS:Data from the 2010-2016 National Health Interview Survey were analyzed in 2018 to estimate vaccination coverage during the 2010-2011 through 2015-2016 seasons. Trends of vaccination in recent years were assessed. Vaccination coverage by race/ethnicity within each group was examined. Multivariable logistic regression and predictive marginal models were conducted to identify factors associated with vaccination, and interactions between race/ethnicity and other demographic and access-to-care characteristics were assessed. RESULTS:Vaccination coverage among adults aged ?18 years increased from 38.3% in the 2010-2011 season to 43.4% in the 2015-2016 season, with an average increase of 1.3 percentage points annually. From the 2010-2011 through 2015-2016 seasons, coverage was stable for adults aged ?65 years and changed by -0.1 to 9.9 percentage points for all other examined subgroups. Coverage in 2015-2016 was 70.4% for adults aged ?65 years, 46.4% for those aged 50-64 years, and 32.3% for those aged 18-49 years; 47.9% for people aged 18-64 years with high-risk conditions; 64.8% for healthcare personnel; and 50.3% for pregnant women. Among adults aged ?18 years for the 2015-2016 season, coverage was significantly lower among non-Hispanic blacks and Hispanics compared with non-Hispanic whites. CONCLUSIONS:Overall, influenza vaccination coverage among adults aged ?18 years increased during 2010-2016, but it remained below the national target of 70%. Vaccination coverage varied by age, risk status, race/ethnicity, healthcare personnel, and pregnancy status. Targeted efforts are needed to improve coverage and reduce disparities.

Project description:BackgroundThe World Health Organization (WHO) does not recommend routine adult booster vaccination for tetanus and diphtheria after completion of the childhood vaccination series. However, many countries continue to implement adult booster vaccinations, leading to the question of whether this is necessary to reduce the incidence of these 2 rare diseases.MethodsWe conducted an observational cohort study based on WHO case reports from 2001 through 2016. We compared the incidence of tetanus and diphtheria in 31 North American and European countries that either do or do not recommend adult booster vaccination.ResultsCountries that vaccinate adults every 5-20 years (group 1) were compared with countries that do not routinely vaccinate adults for tetanus or diphtheria (group 2). Comparison of group 1 vs group 2 revealed no significant decline in tetanus incidence rates among countries that vaccinate adults (P = .52; risk ratio [RR] = 0.78; 95% confidence interval [CI], .36 to 1.70). The risk of contracting diphtheria was increased among countries that vaccinate adults due to inclusion of Latvia, a country that had poor vaccination coverage (P < .001). However, if Latvia is excluded, there is no difference in diphtheria incidence between countries that do or do not routinely vaccinate adults (P = .26; RR = 2.46; 95% CI, .54 to 11.23).ConclusionsReview of >11 billion person-years of incidence data revealed no benefit associated with performing adult booster vaccinations against tetanus or diphtheria. Similar to other vaccines, this analysis supports the WHO position on adult booster vaccination and, if approved by governing health authorities, this may allow more countries to focus healthcare resources on vulnerable and undervaccinated populations.
