Situational assessment of adult vaccine preventable disease and the potential for immunization advocacy and policy in low- and middle-income countries. Vaccine 2021; 39:1556-1564. [PMID: 33618947 PMCID: PMC7960636 DOI: 10.1016/j.vaccine.2021.01.066] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2020] [Revised: 01/24/2021] [Accepted: 01/25/2021] [Indexed: 12/19/2022]
Abstract
By 2050, the number of adults over 65 years of age will be double the under-5 population, and heavily concentrated in low- and middle-income countries. Population growth and increasing life expectancies call for effective healthy aging strategies inclusive of immunization to reduce the burden of vaccine-preventable diseases, improve quality of life, and mitigate antimicrobial resistance. Based on a review of available literature on the pneumococcal disease, influenza, and herpes zoster epidemiology and economic burden, and the health systems and policy barriers for adult immunization, we identified evidence gaps and considerations for prioritizing adult immunization. The body of evidence for adult immunization and the health and economic burden of adult disease is heavily concentrated in high-income countries. The few countries reporting adult immunization policies generally focus on high-risk groups. Despite robust child immunization programs in most countries, adult immunization programs and policies lag far behind and there is a general lack of appropriate delivery platforms. Global adult disease burden and economic costs are substantial but evidence from low- and middle-income countries is limited. There is a need for a strengthened evidence base and political commitment to drive a comprehensive, global technical consensus on adult immunization.

Abstract
BACKGROUND Pneumonias are the most frequent infectious diseases, characterized by a high prevalence especially among children and adults at risk. The socio-economic impact caused by Streptococcus pneumoniae is evaluated in terms of morbidity, death rate and hospitalizations. OBJECTIVE The aim of the study was to demonstrate the potential economic advantages by implementation of an active anti-pneumococcal 13-valent vaccine strategy in Campania region (Southern Italy) in two different categories of subjects, children (aged 0-12), and adults (aged 50- 79) at risk (hypertension, nephropathies, COPD and heart diseases). METHODS Vaccination costs were compared with costs necessary to treat avoidable diseases in the presence and absence of a vaccination program. RESULTS Offering anti-pneumococcal 13-valent vaccine to the paediatric population was quantified as saving one million euros for Italian national health service in two years. In addition, offering anti-pneumococcal vaccine to adults at risk would generate a return of around 29 million euros. CONCLUSION In both cases, offering anti-pneumococcal 13-valent vaccine was proven to be a helpful political health strategy, not only in consideration of a reduction of cases but also in view of the favourable economic impacts.

Abstract
Two vaccines, 23-valent pneumococcal polysaccharide vaccine (PPSV23) and 13-valent pneumococcal conjugate vaccine (PCV13), are widely available for the prevention of pneumococcal disease in adults. However, it is unclear how cost-effective these pneumococcal vaccine choices are in the Hong Kong healthcare environment. We aimed to assess the cost-effectiveness of a sequential administration of PCV13 followed by PPSV23 compared to a single dose of PPSV23 vaccination for pneumococcal disease control in Hong Kong adults aged ≥65 years and individuals aged 20-64 years with immunocompromising and chronic conditions. A previously developed deterministic cohort sequential model was applied to compare the outcomes of two vaccination strategies from a societal perspective. Population-specific model input, including incidence, mortality, case-fatality, risk group distribution, vaccination costs, disease management, and productivity loss, was estimated from a Hong Kong-wide electronic medical database. Costs were valued in US$ in 2017. Vaccination strategies with an incremental cost-effectiveness ratio (ICER, defined as incremental cost per QALY saved) less than one local GDP per capita ($46,193 in 2017) were defined as highly cost-effective. Deterministic sensitivity analyses (SA) were conducted. Compared with single-dose PPSV23, sequential vaccination of PCV13 followed by PPSV23 was cost-saving for adults aged ≥20 years. In the deterministic SA, the base-case results were robust for tested parameter uncertainties. Future vaccination policies should consider the cost-effectiveness of a sequential vaccination strategy as a measure to reduce the vaccine-preventable pneumococcal disease burden in Hong Kong.

Abstract
BACKGROUND Previous systematic reviews concluded that pneumococcal vaccination in the elderly was cost effective. However, recently published economic evaluations state that it may not be cost effective when children are vaccinated with higher-valent pneumococcal conjugate vaccines. The literature suggests that the outcomes of vaccination in the elderly are strongly influenced by the vaccine effectiveness (VE) against the vaccine-type pneumococcal diseases (PD) and the impact of childhood vaccination on the vaccine-type PD incidence in the elderly, but the extent remains unclear. METHODS We conducted a systematic literature search of cost-effectiveness studies on vaccination in the elderly in the PubMed database starting from 2006. We included studies that consider the presence of a childhood vaccination with pneumococcal conjugate vaccine (PCV) 10 and PCV13. We focus on methods and assumptions used in modeling VE and epidemiology of PD over time. RESULTS Twenty-eight economic evaluations underwent full-text review and data extraction. Thirteen were selected for quality assessment. The studies with a higher quality score provide evidence that vaccinating the elderly with PCV13 is not cost effective, when an ongoing rapid decline in the incidence of PCV13-type PD is modeled. A moderate persistence of PCV13 serotypes, in particular due to PCV10 childhood vaccination, makes vaccination of the elderly with PCV13 more attractive. There is no agreement that combining PCV13 with polysaccharide vaccine PPSV23 is cost effective. PPSV23 is attractive when it is effective against non-invasive PD. CONCLUSION Methodological approaches and assumptions in modeling VE and the indirect effects of childhood vaccination have a major impact on outcomes of decision-analytic models and cost-effectiveness estimates. Considering recently observed trends in the epidemiology of pneumococcal serotypes, there is currently inconclusive evidence regarding the cost effectiveness of pneumococcal vaccination of the elderly due to lack of studies that model key serotypes such as serotype 3 separately from other groups of serotypes.

Abstract
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.

Abstract
The Health Technology Assessment (HTA) is a multi-professional and multidisciplinary evaluation approach designed to assess health technology in the broadest sense of the term, from its instruments to the rearranging of its organizational structures. It is by now an established methodology at national and international levels that involves several medical disciplines thanks to its versatility. Laboratory medicine is one of these disciplines. Such specialization was subjected, in recent years, to deep changes even from an organizational standpoint, in order to meet the health needs of the population, making them as effective and cost-effective as possible. In this regard, HTA was the tool used to assess implications in different areas.

Abstract
Community-acquired pneumonia (CAP) places a considerable burden on society. A substantial number of pediatric and adult CAP cases are due to Streptococcus pneumoniae, but fortunately there are effective vaccines available that have a significant impact on CAP-related medical, social, and economic problems. The main aim of this paper is to evaluate the published evidence concerning the impact of pneumococcal vaccines on the prevention of CAP in children and adults. Available data indicate that pneumococcal conjugate vaccines (PCVs) are effective in children, reducing all-cause CAP cases and bacteremic and nonbacteremic CAP cases. Moreover, at least for PCV7 and PCV13, vaccination of children is effective in reducing the incidence of CAP among adults. Recently use of PCV13 in adults alone or in combination with the pneumococcal polysaccharide vaccine has been suggested and further studies can better define its effectiveness in this group of subjects. The only relevant problem for PCV13 is the risk of a second replacement phenomenon, which might significantly reduce its real efficacy in clinical practice. Protein-based pneumococcal vaccines might be a possible solution to this problem.

Abstract
Many evaluations have been performed on the economic impact of pneumococcal vaccination in older adults (>64 y of age) in several countries, including Italy. However, these studies did not include the new data on the effectiveness of 13-valent conjugate pneumococcal vaccine (PCV13) in the elderly reported by the CAPiTA Study. The aim of the present study was to update our previous budget impact analysis of multi-cohort PCV13 vaccination in adults in Italy by including new scientific evidence. We also compared single-cohort vaccination strategies per year, in order to identify the cohort with the most favorable economic profile, in the event of the multi-cohort approach not being economically sustainable for the National Health System (NHS). The new impact analysis highlights that the vaccination of one, two or three adult cohorts per year in Italy would lead to a considerable reduction in pneumococcal disease and its related costs over 5 y. The strategies proved cost-effective (ICERs ranging from €14,605 to €15,412/QALY), i.e. well below the threshold of €50,000/QALY. The ICERs were slightly lower than those calculated in the first published analysis and vaccination continued to be economically favorable. In the case of a mono-cohort strategy, the vaccination of 65-year-old subjects, albeit more expensive, proved to be more favorable than the vaccination of 70- or 75-year-old cohorts. Finally, after the inclusion of the recent clinical evidence, the age-based PCV13 vaccination of the elderly in Italy continued to be economically justified from the NHS perspective in the short period. Vaccination of the elderly should therefore be strongly recommended nationwide in Italy.

Abstract
INTRODUCTION Pneumococcal infection is a public health concern that disproportionately affects the young, the elderly, and the immunocompromised. There is an open debate on the implementation of polysaccharide and/or conjugate vaccines for pneumococcal diseases in adults and the elderly in many countries. The aim of this paper is to systematically review the economic profile of pneumococcal vaccines in adults in terms of costs and benefits. Areas covered: The search for economic studies on pneumococcal vaccination was carried out in Pubmed, Embase, Scopus, and the HTA and NHS EED databases and through a manual search in journals dealing with economic evaluations. We included original articles and reviews with economic evaluation of polysaccharide 23-valent (PPV23) and/or conjugate pneumococcal vaccine 13-valent (PCV13) use in adults, the elderly, and at-risk groups to provide a systematic review of economical evaluation. Expert commentary: Pneumococcal vaccination is strongly recommended for all adults, especially subjects at risk and the elderly. Pneumococcal vaccination with PCV13 or PPV23 in adults is good value for money and should be a priority for the decision-makers. The main issue is how vaccination could be offered.

Abstract
Background Patients with chronic obstructive pulmonary disease (COPD) are at elevated risk of pneumococcal infection. A 13-valent pneumococcal conjugate vaccine (PCV13) was approved for protection against invasive disease and pneumonia caused by Streptococcus pneumoniae in adults. This study estimated the incremental cost-effectiveness ratio (ICER) of vaccinating COPD patients ≥50 years old with PCV13 compared with current vaccination policy (CVP) with 23-valent pneumococcal polysaccharide vaccine. Methods A Markov model accounting for the risks and costs for all-cause non-bacteremic pneumonia (NBP) and invasive pneumococcal disease (IPD) was developed. All parameters, such as disease incidence and costs (€; 2015 values), were based on published data. The perspective of the analysis was that of the Spanish National Healthcare System, and the horizon of evaluation was lifetime in the base case. Vaccine effectiveness considered waning effect over time. Outcomes and costs were both discounted by 3 % annually. Results Over a lifetime horizon and for a 629,747 COPD total population, PCV13 would prevent 2224 cases of inpatient NBP, 3134 cases of outpatient NBP, and 210 IPD extra cases in comparison with CVP. Additionally, 398 related deaths would be averted. The ICER was €1518 per quality-adjusted life-year (QALY) gained for PCV13 versus CVP. PCV13 was found to be cost effective versus CVP from a 5-year modelling horizon (1302 inpatient NBP and 1835 outpatient NBP cases together with 182 deaths would be prevented [ICER €25,573/QALY]). Univariate and probabilistic sensitivity analyses confirmed the robustness of the model. Conclusions At the commonly accepted willingness-to-pay threshold of €30,000/QALY gained, PCV13 vaccination in COPD patients aged ≥50 years was a cost-effective strategy compared with CVP from 5 years to lifetime horizon in Spain.

Abstract
The 13-valent pneumococcal conjugated vaccine (PCV13) is already recommended for some adult groups and is being considered for wider use in many countries. In order to identify the strengths and limitations of the existing economic evaluation studies of PCV13 in adults and the elderly a literature review was conducted. The majority of the studies identified (9 out of 10) found that PCV13 was cost-effective in adults and/or the elderly. However, these results were based on assumptions that could not always be informed by robust evidence. Key uncertainties included the efficacy of PCV13 against non-invasive pneumonia and the herd immunity effect of childhood vaccination programs. Emerging trial evidence on PCV13 in adults from the Netherlands offers the ability to parameterize future economic evaluations with empirical efficacy data. However, it is important that these estimates are used thoughtfully when they are transferred to other settings.

Abstract
RATIONALE, AIMS AND OBJECTIVES Invasive pneumococcal diseases (IPD) are associated with substantial burden in adults (≥50 years). Moreover, adults with vascular, metabolic or respiratory diseases have been shown to have a 3-6 times higher risk of IPD when compared with their healthy controls. These persons at higher risk are likely to benefit most from pneumococcal vaccinations. The 13-valent pneumococcal conjugate vaccine (PCV13) was recently introduced to prevent the 13 most prevalent serotypes causing invasive pneumococcal disease in adults. The objective of this study was to estimate the expected 5-year economic impact of targeted PCV13 vaccination compared with no vaccination in Finnish adults (≥50 years) at moderate or high risk for IPD. METHODS A budget impact model was developed to predict the impact of PCV13 vaccination in terms of the costs and IPD events avoided for years 2012-2016. RESULTS Approximately 35% of the 2.2 million Finns over 50 years of age can be considered to be at moderate or high risk for IPD because of underlying chronic medical conditions. Vaccination of these people with PCV13 could provide an estimated net budget savings of about €218 million compared with the current no-vaccination situation over the next 5 years. Among the risk groups considered, the largest absolute net savings (€66.2 million) could be expected to be obtained by vaccinating people with heart disease, due to its high prevalence in the target population. CONCLUSION In Finland, the immunization with PCV13 vaccine, of adults (≥50 years) at moderate and high risk of IPD, is estimated to lead to substantial cost savings in the 5 years after vaccination.
