Understanding the impact of adult pertussis and current approaches to vaccination: A narrative review and expert panel recommendations.

Pertussis has several notable consequences, causing economic burden, increased strain on healthcare facilities, and reductions in quality of life. Recent years have seen a trend toward an increase in pertussis cases affecting older children and adults. To boost immunity, and protect vulnerable populations, an enduring approach to vaccination has been proposed, but gaps remain in the evidence surrounding adult vaccination that are needed to inform such a policy. Gaps include: the true incidence of pertussis and its complications in adults; regional variations in disease recognition and reporting; and incidence of severe disease, hospitalizations, and deaths in older adults. Better data on the efficacy/effectiveness of pertussis vaccination in adults, duration of protection, and factors leading to poor vaccine uptake are needed. Addressing the critical evidence gaps will help highlight important areas of unmet need and justify the importance of adult pertussis vaccination to healthcare professionals, policymakers, and payers.

The role of funded partnerships in working towards decreasing COVID-19 vaccination disparities, United States, March 2021-December 2022.

During the COVID-19 vaccination rollout from March 2021- December 2022, the Centers for Disease Control and Prevention funded 110 primary and 1051 subrecipient partners at the national, state, local, and community-based level to improve COVID-19 vaccination access, confidence, demand, delivery, and equity in the United States. The partners implemented evidence-based strategies among racial and ethnic minority populations, rural populations, older adults, people with disabilities, people with chronic illness, people experiencing homelessness, and other groups disproportionately impacted by COVID-19. CDC also expanded existing partnerships with healthcare professional societies and other core public health partners, as well as developed innovative partnerships with organizations new to vaccination, including museums and libraries. Partners brought COVID-19 vaccine education into farm fields, local fairs, churches, community centers, barber and beauty shops, and, when possible, partnered with local healthcare providers to administer COVID-19 vaccines. Inclusive, hyper-localized outreach through partnerships with community-based organizations, faith-based organizations, vaccination providers, and local health departments was critical to increasing COVID-19 vaccine access and building a broad network of trusted messengers that promoted vaccine confidence. Data from monthly and quarterly REDCap reports and monthly partner calls showed that through these partnerships, more than 295,000 community-level spokespersons were trained as trusted messengers and more than 2.1 million COVID-19 vaccinations were administered at new or existing vaccination sites. More than 535,035 healthcare personnel were reached through outreach strategies. Quality improvement interventions were implemented in healthcare systems, long-term care settings, and community health centers resulting in changes to the clinical workflow to incorporate COVID-19 vaccine assessments, recommendations, and administration or referrals into routine office visits. Funded partners' activities improved COVID-19 vaccine access and addressed community concerns among racial and ethnic minority groups, as well as among people with barriers to vaccination due to chronic illness or disability, older age, lower income, or other factors.

How ready was the US vaccination infrastructure and network of immunization information systems for COVID-19 vaccination campaigns: Recommendations to strengthen the routine vaccination program and prepare for the next pandemic.

Coronavirus disease 2019 (COVID-19) pandemic vaccination campaigns globally have been unlike any effort in history. In the United States, the success of these efforts, in part, has hinged on the timely capture and reporting of an unprecedented amount of data from a significantly greater number of administering providers than for routine vaccinations. The pandemic response has highlighted the need to explore the status and value of vaccination data as the critical glue that connects all aspects of the upstream US vaccine development and downstream vaccination delivery system. In this review, we examine immunization information systems and the role that data and staffing play in pandemic responses. We offer three strategic recommendations-regarding funding, expanded provider enrollment, and data reporting-informed by a literature review, a survey and focus group from a convenience sample of 22 immunization jurisdictions, and the vision for enhanced data flow to improve future pandemic responses and routine vaccination.

Shared clinical decision-making on vaccines: out of sight, out of mind.

Clinical decision support systems, which provide automated reminders in electronic health systems, are designed to provide physicians and other health professionals support in clinical decision-making. New clinical guidance from the Advisory Committee on Immunization Practices on a new category of recommendations referred to as "shared clinical decision-making" have left providers struggling to interpret how to best implement recommendations for adult vaccines. The issue at hand is how to ensure that a conversation between the patient and provider occurs. While traditional clinical decision support systems have driven immunization for years, these systems support a binary default opt-in process. The goal for shared decision-making is the discussion rather than the vaccination. The recommended provider-patient conversations need to be supported with both provider guidance as well as tools to ensure vaccines are not omitted from the conversations, particularly as future vaccine candidates progress through the vaccine development pipeline.

The epidemiologic and biologic basis for classifying older age as a high-risk, immunocompromising condition for pneumococcal vaccine policy.

INTRODUCTION: Immunosenescence is a normal biologic process involving deterioration of protective immune responses. Consequently, older adults experience increased risk of infectious diseases, particularly pneumonia, and its leading bacterial cause, Streptococcus pneumoniae. Pneumococcal vaccine recommendations are often limited to adults with specific medical conditions despite similar disease risks among older adults due to immunosenescence. AREAS COVERED: This article reviews epidemiologic, biologic, and clinical evidence supporting the consideration of older age due to immunosenescence as an immunocompromising condition for the purpose of pneumococcal vaccine policy and the role vaccination can play in healthy aging. EXPERT OPINION: Epidemiologic and biologic evidence suggest that pneumococcal disease risk increases with age and is comparable for healthy older adults and younger adults with immunocompromising conditions. Because immunocompromising conditions are already indicated for pneumococcal conjugate vaccines (PCVs), a comprehensive public health strategy would also recognize immunosenescence. Moreover, older persons should be vaccinated before reaching the highest risk ages, consistent with the approach for other immunocompromising conditions. To facilitate PCV use among older adults, vaccine technical committees (VTCs) could classify older age as an immunocompromising condition based on the process of immunosenescence. With global aging, VTCs will need to consider immunosenescence and vaccine use during healthy aging.

Financial impact to providers using pediatric combination vaccines.

OBJECTIVE: To understand the financial impact to providers for using a combination vaccine (Pediarix [GlaxoSmithKline Biologicals, King of Prussia, PA]) versus its equivalent component vaccines for children aged 1 year or younger. METHODS: Using a subscription remittance billing service offered to private-practice office-based physicians, we analyzed charge and payment information submitted by providers to insurance payers from June 2007 through July 2009. We analyzed provider and payer characteristics, payer comments, and the ratio of vaccine product to immunization administration (IA) codes and computed total charges and payments to providers for both arms of the study. RESULTS: Most providers in our data set were pediatricians (74%), and most payers were commercial (75%), primarily managed care. The ratio of the number of vaccine products to the number of IAs was 1:1 in the majority of the claims. Twenty percent of claims were paid with no adjustment by the payer, whereas 76% of the claims were adjusted for charges that exceeded the contract arrangement or the fee schedule. Providers received $23 less from commercial payers and $13 less from Medicaid for the use of Pediarix compared with the equivalent component vaccines. The mean commercial payment was greater for age-specific Current Procedural Terminology IA codes 90465 and 90466 than for non-age-specific codes 90471 and 90472, whereas the reverse was true for Medicaid. CONCLUSIONS: Providers who administer vaccines to children face a reduction in payment when choosing to provide combination vaccines. The new IA codes should be monitored for correction of financial barriers to the use of combination vaccines.
