 We've had a vaccine for over a century, but 10 million people get tuberculosis every year, and one in ten die from it. If TB is preventable, why is it still our most deadly infectious disease? Well, a clear lack of policy focus, as well as funding, has slowed down the development of new treatments. We have only one licensed vaccine in the world, and its effectiveness can be limited, especially for teens and adults. Even where antibiotics are easily available, it can take months and months to finish a course. Though for most people with TB, they can't even access these treatments. 80% of cases and deaths affect low- to middle-income countries. With more drug-resistant strains of the disease emerging, we need new research, investment in ideas. Luckily, there's been major breakthroughs in new vaccines recently, and in 2023, the WHO announced plans to set up a new vaccine council. But only with more global collaboration and funding will we move closer to a future without TB.
