This article is part of a series of explainers on vaccine development and distribution. Learn more about vaccines – from how they work and how they’re made to ensuring safety and equitable access – in WHO’s Vaccines Explained series.
Vaccines are supported by decades of medical research. ...They work by preparing the body's own immune system to recognise and defend against a specific disease. The volume of information available about vaccination can be overwhelming, so it’s important to talk through the topic.

Integrating neglected tropical diseases into global health and development: fourth WHO report on neglected tropical diseases evaluates the changing global public health landscape; assesses progress towards the 2020 targets; and considers the possible core elements of a strategic vision to integratin...g neglected tropical diseases into the 2030 Agenda of the Sustainable Development Goals.
Advances have been made through expanded interventions delivered through five public health approaches: innovative and intensified disease management; preventive chemotherapy; vector ecology and management; veterinary public health services; and the provision of safe water, sanitation and hygiene. In 2015 alone nearly one billion people were treated for at least one disease and significant gains were achieved in relieving the symptoms and consequences of diseases for which effective tools are scarce; important reductions were achieved in the number of new cases of sleeping sickness, of visceral leishmaniasis in South-East Asia and also of Buruli ulcer.
The report also considers vector control strategies and discusses the importance of the draft WHO Global Vector Control Response 2017–2030. It argues that veterinary public health requires a multifaceted approach across the human–animal interface as well as a multisectoral programme of work to protect and improve the physical, mental and social well-being of humans, including veterinary, water, sanitation and hygiene.
Integration of activities and interventions into broader health systems is crucial, and despite challenges, has the potential to accelerate progress towards universal health coverage while advancing the 2030 Agenda.
In short, this report drives the message home that “no one must be left behind”.

This publication articulates the WHO Botswana Country Office’s focus and investment needs for the biennium 2022–2023, building on achievements, networks, and partnerships fostered in 2020-2021.
As the leading health authority within the United Nations system in Botswana, the WHO Country Offi...ce has been at the forefront of supporting the government to improve health since 1996. The WHO Country Office supports the Ministry of Health in realizing the health goals the Government of Botswana defines. Acknowledging that as an upper middle-income country, Botswana provides the bulk of its resources for implementing health programmes, the WHO directly brings technical expertise to the table by collaborating with relevant partners. Where the country office has limitations in terms of human resources with the requisite expertise to answer the country’s needs, the regional level and headquarters of the WHO will be mobilized to provide the necessary support.

Uganda confirmed the first cases of mpox on 24 July 2024 following the confirmation of two case-patients from Kasese District, Bwera Hospital by the Uganda Virus Research Institute (UVRI) through a routine sentinel surveillance system. Cumulatively, 80 confirmed cases of mpox have been registered.
Preliminary data from Member States indicate that the number of cholera cases reported in 2023 as of 15 December has surpassed that of 2022, with over 667 000 cases and 4000 deaths. These figures must be interpreted with caution given the varying surveillance systems and capacity across countries, w...hich means that 2023 data are not directly comparable to reports from previous years.
