New TB vaccines could save millions of lives

Gavi, a global vaccine alliance, announced that new tuberculosis (TB) vaccines, expected to be available from 2029, could save over seven million lives from 2030 to 2050.
Tuberculosis continues to be the world’s leading infectious disease, causing an estimated 1.23 million deaths in 2024. Currently, the only available vaccine, BCG, protects infants and young children but its effectiveness decreases over time.
Gavi believes these new vaccines, designed for adolescents and adults, could become a major tool in fighting the disease, but only if enough doses reach the countries where TB is most prevalent. A recent analysis by the organisation also found the vaccines could generate up to $135 billion in economic benefits for low- and middle-income countries by 2050. However, Gavi cautioned that securing adequate funding and ensuring manufacturers can produce enough vaccines remain significant obstacles.
The organisation is working with partners to prepare for vaccine distribution and encourage the development of a diverse range of TB vaccine candidates. Gavi intends to advocate for the vaccines’ inclusion in routine immunisation programs to maximise their impact.
