WHO has been working closely with national governments to provide economic data on the burden of disease, the cost effectiveness of vaccines, and the projected implementation costs of immunization programmes in their countries to help decision makers better allocate their resources to reach universal health coverage.

A series of tools and resource documents have been developed to assess the economic and social benefits of introducing vaccines.

School children living in areas close to the Rohingya camps are being administered a dose of DT vaccine as part of the diphtheria outbreak response.

WHO prequalified the first conjugate vaccine for typhoid, Bharat Biotech’s Typbar-TCV®. Typhoid conjugate vaccines (TCVs) are innovative products that have longer-lasting immunity than older vaccines, require fewer doses, and can be given to young children through routine childhood immunization programs.

The fact that the vaccine has been prequalified by WHO means that it meets acceptable standards of quality, safety and efficacy. This makes the vaccine eligible for procurement by UN agencies, such as UNICEF, and Gavi, the Vaccine Alliance.
