Africa: New TB Vaccines Could Save 7.3 Million Lives, but Africa Must Prepare Now

What the report says

More than a century after the BCG vaccine became the only licensed vaccine against tuberculosis, Gavi says a new generation of TB vaccines could begin reaching countries in 2029. In an AllAfrica interview published from Gavi’s perspective, the alliance said the next wave of vaccines could save an estimated 7.3 million lives between 2030 and 2050, but only if governments and health partners start preparing now.

The report says TB remains one of the world’s deadliest infectious diseases and that Africa continues to record the highest burden of cases and deaths. It notes that existing tools have helped, but major gaps persist in diagnosis, treatment access and prevention, especially in poorer communities and places with fragile health systems. Gavi’s vaccine programmes director, Emily Kobayashi, said the current BCG vaccine still protects young children from severe TB, but offers limited protection against pulmonary TB in adolescents and adults, who drive most transmission.

The article stresses that vaccine success will depend not just on trial results, but also on supply, financing and delivery planning. Gavi’s roadmap suggests global demand could average 86 million vaccination courses a year, with high-burden countries needing the earliest and largest supplies. The organisation says manufacturers need clearer signals about future demand to invest in production capacity before approval.

More broadly, the piece frames TB vaccination as both a health and economic issue for Africa and other low- and middle-income countries. It adds, as general background, that earlier coordination has helped speed other vaccine rollouts, and that a successful TB vaccine could also reduce drug-resistant TB by preventing new infections in the first place.
