Ending TB will require sustained investment in research and innovation.




While new diagnostic tools represent a critical step forward, ending TB will require sustained investment in research and innovation. Global funding for TB research remains far below the estimated annual need of around US$ 5 billion, leaving major gaps in the development of new diagnostics, medicines and vaccines needed to end the epidemic.

The WHO is working with partners to accelerate progress through initiatives such as the TB Vaccine Accelerator Council, launched to fast-track the development and equitable access to new TB vaccines by aligning governments, researchers, funders and industry around shared priorities and coordinated investment.

As countries mark World TB Day 2026, WHO urges governments and partners to prioritize TB as a central pillar of health security and universal health coverage.
