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.

COVID-19 vaccines have proven to be safe, ...effective and life-saving. Like all vaccines, they do not fully protect everyone who is vaccinated, and we do not yet know how well they can prevent people from transmitting the virus to others. So as well as getting vaccinated, we must also continue with other measures to fight the pandemic.

The new WHO recommendations for rabies immunization supersede the 2010 WHO position
on pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) for rabies. These updated
recommendations are based on new evidence and directed by public health needs that are cost-,
dose- and time-sparing..., while assuring safety and clinical effectiveness. In addition, new guidance on
prudent use of rabies immunoglobulins (RIG) is provided.
The following sections summarize the main points of the updated WHO position as endorsed by the
Strategic Advisory Group of Experts on immunization (SAGE) at its meeting in October 20171. The full
version of the WHO position on rabies vaccines and immunoglobulins will be published in the Weekly
Epidemiological Record2 in April 2018.
Rabies prevention involves two main strategies: (i) dog vaccination to interrupt virus transmission to
humans; and (ii) human vaccination as a series of vaccine administrations before or after an exposure.
Currently, rabies vaccines made from inactivated cell cultures are extremely well tolerated and have no
contraindications.

The COVID-19 vaccine tracker and landscape compiles detailed information of each COVID-19 vaccine candidate in development by closely monitoring their progress through the pipeline.
The COVID-19 vaccine tracker:
Provides summary tables of COVID-19 vaccine candidates in both clinical and pre-...clinical development;
Provides analysis and visualization for several COVID-19 vaccine candidate categories;
Tracks the progress of each vaccine from pre-clinical, Phase 1, Phase 2 through to Phase 3 efficacy studies and including Phase 4 registered as interventional studies;
Provides links to published reports on safety, immunogenicity and efficacy data of the vaccine candidates;
Includes information on key attributes of each vaccine candidate and
Allows users to search for COVID-19 vaccines through various criteria such as vaccine platform, schedule of vaccination, route of administration, developer, trial phase and clinical endpoints.
The database is updated regularly - twice a week (Tuesday and Friday, 17:00 CET).

This chronology of facts has challenged public health systems worldwide and regulatory bodies are no exception. Regulatory authorities with mechanisms in place to authorize the use of investigational products had to development guidelines and procedures, create task forces and alliances to maximize ...the efficiency of assessment, review and authorizations of medical products. Vaccines are undoubtedly the most complex medical products to develop, from concept to a stage where sufficient evidence of quality, safety and efficacy are collected to provide an assurance that their use will provide more benefits than risks when used in the context of a public health emergency.

Interim Guidance, 12 July 2021; This tool was developed to assess present and surge capacities for the treatment of COVID-19 in health facilities. It allows health facilities to assess the availability and status of stockout of critical COVID-19 medicines, equipment and supplies on site and to ident...ify areas that need further attention to enable the facility to respond effectively to the pandemic. The tool encompasses key components that are essential to managing COVID-19 in a hospital setting, including:
health workforce (numbers, absences, COVID-19 infections, staff vaccinated for COVID-19 health workforce management, training and support);
medicines and medical supplies for management of COVID-19;
IPC capacities (protocols, safety measures, guidelines) and the availability of personal protective equipment (PPE) for staff;
diagnostic testing, imaging and patient monitoring devices and supplies
medical equipment for management of COVID-19, including O2 administration;
COVID-19 vaccine readiness ;
beds and space capacity.

August 2020, The Africa Joint Continental Strategy for COVID-19 is underpinned by the need to limit transmission, prevent deaths and reduce associated harms. Participation by African nations in clinical trials is an essential step to ensure that sufficient data is generated on the safety and efficac...y of the most promising vaccine candidates among the region’s populations.
While current COVID-19 clinical trial activity on the continent is limited, Africa has substantial experience and capabilities to conduct clinical trials for preventative vaccines across a range of diseases, and many organizations on the continent are working tirelessly to help prepare additional trials on potential COVID-19 vaccines. As the number of candidate vaccines in the development pipeline continues to increase, it will be important for organizations responsible for managing clinical trials in the region to partner with vaccine developers to identify potential and appropriate trial locations, provide support to remove any critical obstacles impeding commencement and progress of trials, and to provide oversight ensuring that trials are conducted safely and ethically.
