ing a life course approach (LCA) to immunization, vaccination programs can be tailored to close immunity gaps at different stages of life. The life course approach foresees the establishment of multiple strategies to reduce missed opportunities for vaccination according to age group. This technical document explains the key concepts of the LCA with a focus on immunization by vaccination, as well as the underlying biological mechanisms that require the application different vaccines at different life stages according to changes to the immune system and in the epidemiological situation of a community.

Terminology used to describe the transmission of pathogens through the air varies across scientific disciplines, organizations and the general public. While this has been the case for decades, during the coronavirus disease (COVID-19) pandemic, the terms ‘airborne’, ‘airborne transmission’ a
...
nd ‘aerosol transmission’ were used in different ways by stakeholders in different scientific disciplines, which may have contributed to misleading information and confusion about how pathogens are transmitted in human populations.
This global technical consultation report brings together viewpoints from experts spanning a range of disciplines with the key objective of seeking consensus regarding the terminology used to describe the transmission of pathogens through the air that can potentially cause infection in humans.
This consultation aimed to identify terminology that could be understood and accepted by different technical disciplines. The agreed process was to develop a consensus document that could be endorsed by global agencies and entities. Despite the complex discussions and challenges, significant progress was made during the consultation process, particularly the consensus on a set of descriptors to describe how pathogens are transmitted through the air and the related modes of transmission. WHO recognizes the important areas where consensus was not achieved and will continue to address these areas in follow-up consultations.

in CHW motivation for
high-quality care delivery. Few studies have described the CHW perspective on intrinsic and extrinsic motivation to
enhance their programmatic activities.
Methods: We utilized an exploratory qualitative study design with CHWs employed in the household model in Neno
District, Malawi, to explore their perspectives on intrinsic and extrinsic motivators and dissatisfiers in their work. Data
was collected in 8 focus group discussions with 90 CHWs in October 2018 and March–April 2019 in seven purposively
selected catchment areas. All interviews were audiotaped, transcribed verbatim, coded, and analyzed using Dedoose.
Results: Themes of complex intrinsic and extrinsic factors were generated from the perspectives of the CHWs in
the focus group discussions. Study results indicate that enabling factors are primarily intrinsic factors such as positive
patient outcomes, community respect, and recognition by the formal health care system but can lead to the chal-
lenge of increased scope and workload. Extrinsic factors can provide challenges, including an increased scope and
workload from original expectations, lack of resources to utilize in their work, and rugged geography. However, a posi-
tive work environment through supportive relationships between CHWs and supervisors enables the CHWs.
Conclusion: This study demonstrated enabling factors and challenges for CHW performance from their perspec-
tive within the dual-factor theory. We can mitigate challenges through focused efforts to limit geographical distance,
manage workload, and strengthen CHW support to reinforce their recognition and trust. Such programmatic empha-
sis can focus on enhancing motivational factors found in this study to improve the CHWs’ experience in their role. The
engagement of CHWs, the communities, and the formal health care system is critical to improving the care provided
to the patients and communities, along with building supportive systems to recognize the work done by CHWs for
the primary health care systems.

It includes three sections: description of major problems that may be faced during the donation process, listing of best practices for donors and recipients and addressing situations requiring special attention. It also has three annexes for further reading: the criteria for the acceptability of a donation, literature review on donations of medical devices between 2010 and 2023 and a flyer. This document is intended to improve the quality of medical devices donations, including medical equipment, single-use medical devices and in-vitro diagnostics, to provide maximum benefit to all stakeholders. The considerations can be used to develop institutional or national policies and regulations for medical devices donations. This document is intended for use by any organization, expert or practitioner involved in the donation, procurement, management of medical devices, including health workers, biomedical engineers, health managers, policymakers, donors, nongovernmental organizations and academic institutions.

TB preventive treatment (TPT) given to people at highest risk of progressing from TB infection to disease remains a critical element to achieve the global targets of the End TB Strategy, as reiterated by the second UN High Level Meeting on TB in 2023. Delivering TPT effectively and safely necessitates a programmatic approach to implement a comprehensive package of interventions along a cascade of care: identifying individuals at highest risk, screening for TB and ruling out TB disease, testing for TB infection, and choosing the preventive treatment option that is best suited to an individual, managing adverse events, supporting medication adherence and monitoring programmatic performance

ble challenges to securing long-term polio vaccine security.
This framework is designed to enhance the efforts of existing structures and workstreams within the Global Polio Eradication Initiative (GPEI) and other stakeholders by improving communication and coordination on vaccine security. Ensuring vaccine security is crucial for maintaining a timely, sustained, and uninterrupted supply of affordable, quality-assured polio vaccines in the global fight to achieve and sustain a polio-free world. However, challenges such as fragmented approaches, short-term planning, a dynamic policy environment, and a diverse product pipeline present significant risks to long-term vaccine security. This framework emphasizes the need for alignment and coordination across key polio operational domains, including Poliovirus Containment, Research and Development, and Vaccine Manufacturing and Supply. It also underscores the critical role of normative frameworks and policies in shaping long-term vaccine strategies that guide these operational areas. Additionally, it highlights the importance of cross-cutting elements such as financing and access to resources, along with the integration of communication, coordination, and advocacy efforts, as essential enablers for achieving vaccine security. To secure long-term vaccine supply, it is imperative to enhance alignment and strengthen coordinated efforts across workstreams and with stakeholders, including vaccine manufacturers.
Recognizing that vaccine security is an ongoing endeavor, requiring continuous monitoring and adaptation, this framework will undergo regular updates and revisions. Initially, the management of the framework will be carried out by the GPEI Vaccine Supply Group (VSG).
