Value profile for respiratory syncytial virus vaccines and monoclonal antibodies.

Respiratory syncytial virus (RSV) is the predominant cause of acute lower respiratory infection (ALRI) in young children worldwide, yet no licensed RSV vaccine exists to help prevent the millions of illnesses and hospitalizations and tens of thousands of young lives taken each year. Monoclonal antibody (mAb) prophylaxis exists for prevention of RSV in a small subset of very high-risk infants and young children, but the only currently licensed product is impractical, requiring multiple doses and expensive for the low-income settings where the RSV disease burden is greatest. A robust candidate pipeline exists to one day prevent RSV disease in infant and pediatric populations, and it focuses on two promising passive immunization approaches appropriate for low-income contexts: maternal RSV vaccines and long-acting infant mAbs. Licensure of one or more candidates is feasible over the next one to three years and, depending on final product characteristics, current economic models suggest both approaches are likely to be cost-effective. Strong coordination between maternal and child health programs and the Expanded Program on Immunization will be needed for effective, efficient, and equitable delivery of either intervention. This 'Vaccine Value Profile' (VVP) for RSV is intended to provide a high-level, holistic assessment of the information and data that are currently available to inform the potential public health, economic and societal value of pipeline vaccines and vaccine-like products. This VVP was developed by a working group of subject matter experts from academia, non-profit organizations, public private partnerships and multi-lateral organizations, and in collaboration with stakeholders from the WHO headquarters. All contributors have extensive expertise on various elements of the RSV VVP and collectively aimed to identify current research and knowledge gaps. The VVP was developed using only existing and publicly available information.

Experiences with Medicaid Renewal and Reauthorization Policies in the Context of Child Health and Vaccine Coverage.

Difficulties complying with Medicaid recertification requirements may be responsible for a portion of Medicaid disenrollments and may impact access to preventive care. This study aimed to explore the barriers parents experienced renewing their child's Medicaid, how those barriers impact access to healthcare, and how changes in Medicaid policy can improve child health outcomes. To understand the barriers associated with Medicaid renewal, authors conducted in-depth interviews (N = 24) with racially and demographically diverse parents living in Baltimore. They found that administrative burden, lack of awareness regarding reauthorization, challenges with navigation assistance, and lack of access to the renewal system were crucial barriers to renewing Medicaid. Many participants identified negative impacts on child health outcomes resulting from lapses in coverage, including lack of healthcare access and missed immunizations. Drawing on these findings, the authors provide recommendations for streamlining and clarifying the Medicaid renewal process in Maryland, and the role of social work policy and practice in reducing barriers to renewal.

Effect of educational and financial incentive-based interventions on immunization attitudes, beliefs, intentions and receipt among close contacts of pregnant women.

INTRODUCTION: Cocooning, the vaccination of close contacts of a newborn, is a strategy to limit the risk of pertussis and influenza infection among vulnerable infants. METHODS: Pregnant women in Colorado and Georgia referred close contacts to an app that provided tailored educational videos about vaccines along with a small pharmacy-based financial incentive for vaccine receipt. The primary objective of this study was to determine the feasibility of implementing this app-based cocooning intervention. RESULTS: Two hundred seventy seven contacts were enrolled in this study. Of those who received the educational videos, 96% found them interesting, 100% found them clear to understand, 97% found them helpful, and 99% trusted them. Completion of the videos led to significant increases in influenza vaccine knowledge (p = 0.025), Tdap vaccine knowledge (p < 0.001), and intention to receive these vaccines (p = 0.046). Of the 136 participants who reported receiving influenza vaccine, 41 (30%) reported receiving it at a pharmacy, and of the 66 who reported receiving Tdap vaccine, 15 (23%) reported receiving it at a pharmacy. Of all participants, 80% reported being comfortable receiving vaccines at a pharmacy instead of a doctor's office. The provision of small pharmacy-based financial incentives combined with individually-tailored educational videos about vaccines led to 6.97 (95%CI: 2.25-21.64) times higher odds of self-reported receipt of influenza vaccine than providing small pharmacy-based financial incentives without these videos. No significant difference was found for Tdap vaccine. CONCLUSIONS: Tailored vaccine education can positively impact vaccine knowledge and intentions among adults. An app-based referral program providing education and financial incentives for cocooning vaccination at pharmacies is feasible.

Racial/Ethnic Disparities in Maternal Vaccine Knowledge, Attitudes, and Intentions.

OBJECTIVES: Although disparities in maternal vaccine acceptance among racial/ethnic groups are well documented, the reasons for these disparities are unclear. The objective of this study was to describe differences in pregnant women's knowledge, attitudes, beliefs, intentions, and trust regarding maternal and infant vaccines by race/ethnicity. METHODS: We collected survey data from 1862 pregnant women from diverse prenatal care practices in Georgia and Colorado from June 2017 through July 2018. We performed multiple logistic regressions to determine differences in intentions, knowledge, attitudes, beliefs, and trust by race/ethnicity and calculated odds ratios (ORs) and 95% CIs. RESULTS: Compared with White women, Black and Hispanic women were less confident in vaccine safety and efficacy and less likely to perceive risk of acquiring vaccine-preventable diseases, report provaccine social norms, indicate having enough vaccine knowledge, and trust vaccine information from health care providers and public health authorities. Black women were the least confident in the safety of the maternal influenza vaccine (OR = 0.37; 95% CI, 0.27-0.49); maternal tetanus, diphtheria, and acellular pertussis vaccine (OR = 0.37; 95% CI, 0.27-0.52); and infant vaccines overall (OR = 0.40; 95% CI, 0.28-0.58), and were least likely to intend to receive both maternal vaccines (OR = 0.35; 95% CI, 0.27-0.47) or all infant vaccines on time (OR = 0.45; 95% CI, 0.34-0.61) as compared with White women. CONCLUSIONS: Understanding differences in behavioral constructs integral to vaccine decision making among women of different races/ethnicities can lead to tailored interventions to improve vaccine acceptance.

Vaccine decision-making among parents of children on Medicaid with and without autism spectrum disorder.

BACKGROUND: The belief that there is a link between the MMR vaccine and autism has led to a decline in childhood-immunization uptake and a resurgence of preventable infectious diseases. This study aimed to understand how the vaccine decision-making process differed between parents with a child diagnosed with autism and parents with a child that did not have autism. METHODS: Interviews were conducted in September-December 2018 with 24 racially and demographically diverse parents of children on Medicaid at two Baltimore clinics serving Medicaid patients, one of which only serves families of children with autism. We conducted a semi-structured, qualitative, in-person in-depth interview study to explore parental perceptions of vaccine-decision making. Interviews with participants were transcribed from audio recordings. We then extracted and analyzed the types of barriers each participant experienced. RESULTS: Parent descriptions of their vaccine decision-making process focused on three primary factors: concerns about vaccines, the relationship between the child's provider and the parent, and risk perception. These findings are in line with existing literature that has articulated key factors in the vaccine decision-making process generally. Parents of a child with autism were more likely to consider the idea that vaccines were linked to autism in their decision-making process, and were less likely to be influenced by personalized recommendations from the child's health care provider. CONCLUSION: Parental concerns about vaccines, the parent-provider relationship, and vaccine risk perception all contribute to vaccine decision-making among parents of children with and without ASD. However, providers may find it especially difficult to manage parental misconceptions about vaccines and developmental disabilities. Future studies can identify alternative communication techniques and determine what mechanisms may be more effective in encouraging vaccine acceptance among parents of children with ASD.

Characterizing mothers and children at risk of being under-immunized in India: A latent class analysis approach.

OBJECTIVES: While India has made substantial progress in introducing new vaccines and scaling up immunization coverage, inequities persist sub-nationally. This study was performed to investigate the risk of under-immunization based on class membership and to identify heterogeneous classes based on sociodemographic characteristics in pediatric and maternal populations in India through latent class analysis. METHODS: Data from the most recent National Family Health Survey conducted in 2015-2016 were used. Latent class analysis was used to model immunization coverage in children aged 12-23 months and mothers, and to identify subgroups to characterize those at risk of not being immunized. RESULTS: Patterns of sociodemographic characteristics were found to contribute to non-immunization or under-immunization among pediatric and maternal populations in India. Individuals who fit into one of three categories were identified in both populations: those at high, medium, and lower risk of not being immunized. Lower socioeconomic status, lack of antenatal care, and lower maternal education put individuals at higher risk of not being immunized with routine childhood vaccines and maternal tetanus toxoid. CONCLUSIONS: Predisposing risk factors can persistently impact immunization status despite improvements in immunization access in India. Tailored programmatic interventions should be developed to improve immunization coverage among those children and mothers who are at highest risk of being under-immunized or not immunized.

The Mid-Atlantic Center for AIDS Research Consortium Scholars Program: A Multi-Institutional Approach to Mentoring the Next Generation of Underrepresented Scientists.

BACKGROUND: There is an urgent need to intentionally develop and expand mentoring for junior faculty from underrepresented communities in the area of HIV research. Such a goal is increasingly recognized as essential across all scientific fields because profound disparities exist regarding which doctorally prepared individuals ultimately end up entering research fields in academic settings. The purpose of this article is to describe a novel inter-Center for AIDS Research (CFAR) program designed to support underrepresented scientists in research to address the HIV epidemic in the Mid-Atlantic region. METHODS: Three CFARs in the Mid-Atlantic region (the District of Columbia, Johns Hopkins University CFAR, and University of Pennsylvania CFARs) developed a Scholars program designed for underrepresented minority scholars interested in studying the HIV epidemic in the region. The program provided resources for scholarship as well as cross-institutional mentoring and training. RESULTS: Scholars in the first cohort have been successful in implementing novel research that informs our understanding of the HIV epidemic in the region as well as increasing skills, publications, and grant submissions and funded applications. Lessons learned from the first cohort will inform future years of the MACC Scholars Program. CONCLUSIONS: The MACC Scholars Program offers a model for other inter-CFAR collaborations wishing to find novel ways to support the next generation of scientists.

Exploring California's new law eliminating personal belief exemptions to childhood vaccines and vaccine decision-making among homeschooling mothers in California.

BACKGROUND: California's Senate Bill 277 (SB-277) law eliminated the personal belief exemption to school immunization requirements. A potential consequence may be that parents choose homeschooling to avoid immunization. Vaccine attitudes and behaviors have not been well studied among the home-schooling population. This study explored the effect of SB-277 and vaccine decision-making among California home schoolers. METHODS: Purposive and snowball sampling were used recruit home-schooling parents through home-schooling Facebook groups based on home school type in high-exemption regions in California for in-depth interviews. Participants had to have a child in a legalized form of homeschooling in California in grades kindergarten-twelfth grade. RESULTS: Twenty-four mothers were interviewed. Participants were categorized based on self-reported vaccine attitudes and behavior into three groups: Confident and Accepting, Hesitant and Accepting, and Skeptical and Refusing. All reported the belief that SB-277 is an infringement on parental rights but was not currently impacting them. Confident and Accepting mothers (n = 10) generally believed vaccinations were safe, effective, and posed a lower risk than vaccine preventable disease (VPD). Hesitant and Accepting mothers (n = 5) expressed varying confidence levels in the belief that vaccinations were safe and effective, were not confident in the belief that vaccination posed lower risks than VPD risk, and risk perception affected vaccine decision-making. Skeptical and Refusing mothers (n = 9) generally believed that vaccinations were unsafe and ineffective, refused select vaccines, believed that vaccination posed a more serious risk than VPD risks, and belief of vaccine harm was a salient factor in vaccine decision-making. CONCLUSION: Home-schooling mothers were concerned about SB-277 but did not report that it was directly impacting their children, their vaccine decisions, or reason to home school. Vaccine attitudes and beliefs among homeschooling mothers broadly fell into categories similar to parents of non-home-schooled children. Future quantitative studies should measure vaccine hesitancy and refusal prevalence and potential confounders.

Looking Through a Social Lens: Conceptualising Social Aspects of Knowledge Management for Global Health Practitioners.

Knowledge management plays a critical role in global health. Global health practitioners require knowledge in every aspect of their jobs, and in resource-scarce contexts, practitioners must be able to rely on a knowledge management system to access the latest research and practice to ensure the highest quality of care. However, we suggest that there is a gap in the way knowledge management is primarily utilized in global health, namely, the systematic incorporation of human and social factors. In this paper, we briefly outline the evolution of knowledge management and then propose a conceptualization of knowledge management that incorporates human and social factors for use within a global health context. Our conceptualization of social knowledge management recognizes the importance of social capital, social learning, social software and platforms, and social networks, all within the context of a larger social system and driven by social benefit. We then outline the limitations and discuss future directions of our conceptualization, and suggest how this new conceptualization is essential for any global health practitioner in the business of managing knowledge.

Leveraging the Power of Knowledge Management to Transform Global Health and Development.

Good knowledge is essential to prevent disease and improve health. Knowledge management (KM) provides a systematic process and tools to promote access to and use of knowledge among health and development practitioners to improve health and development outcomes. KM tools range from publications and resources (briefs, articles, job aids) and products and services (websites, eLearning courses, mobile applications), to training and events (workshops, webinars, meetings) and approaches and techniques (peer assists, coaching, after-action reviews, knowledge cafés).

Informal alcohol in Malawi: stakeholder perceptions and policy recommendations.

Through the eyes of those involved in the alcohol policy-making process in Malawi, we explored the role of informal (non-commercial) alcohol in rural communities, its harmful effects, and implications for appropriate national policy. Harms included early drinking initiation, violence, and sexual risk exposure. Informants suggested that policy should address informal alcohol's content, selling times, and easy access. Because most informal alcohol producers are women who rely upon sales for subsistence, policies must avoid limiting women's economic opportunities while protecting community health.

Alcohol consumption among high-risk Thai youth after raising the legal drinking age.

OBJECTIVE: Methamphetamine and alcohol are the leading substances abused by Thai youth. In 2008 the government passed laws that limited alcohol availability and increased the legal drinking age from 18 to 20. We assessed whether the law reduced drinking among methamphetamine-using 18-19 year olds in Chiang Mai. METHOD: The study compares drinking patterns among methamphetamine smokers aged 18-19 years (n=136) collected prior to the legal changes, to a comparable post-law sample (n=142). Statistical tests for differences between the pre- and post-law samples on problem drinking and recent drinking frequency and drunkenness were conducted. Logistic regression modeled the relative odds of frequent drunkenness, controlling for demographic characteristics. RESULTS: A high prevalence of problematic drinking was present in both samples, with no difference detected. The post-law sample reported a significantly higher median days drunk/month (9 vs. 4, p≤0.01); in adjusted analysis, frequent drunkenness (>5.5 days/month) was more common in the post-law compared to pre-law period in the presence of other variables (AOR: 2.2; 95%CI: 1.3, 3.9). Post-law participants demonstrated a low level of knowledge about the law's components. CONCLUSIONS: The study suggests that the new laws did not reduce drinking among high-risk, methamphetamine-smoking 18-19 year olds; rather, the post-law period was associated with increased drinking levels. The data indicate that the law is not reaching high-risk under-aged youth who are at risk of a number of deleterious outcomes as a result of their substance use.

A qualitative exploration of the effects of increasing the minimum purchase age of alcohol in Thailand.

INTRODUCTION AND AIMS: Although prevalence of alcohol consumption has been relatively stable among Thai youth, concerns over alcohol-related harms affecting youth influenced the passage of new laws in early 2008, which made it illegal to sell alcohol to anyone under the age of 20. This qualitative study explored the effects of the law on the purchasing patterns of underage Thai bar patrons, in order to understand the strategies employed by underage youth to circumvent the law. DESIGN AND METHODS: A total of 41 in-depth interviews were conducted with 18- to 19-year-old bar patrons in Chiang Mai, Thailand. RESULTS: Underage Thai bar patrons frequented shops where enforcement was not strict and purchased alcohol from familiar shopkeepers in their neighbourhoods. Participants suggested that purchasing alcohol was relatively easy as long as shopkeepers were driven by the need to make a profit. DISCUSSION AND CONCLUSIONS: To address alcohol-related harms, the control law must be enforced in a meaningful way to deter youth from purchasing alcohol. Otherwise, the law will have minimal effectiveness in reducing the harms associated with alcohol.
