100 years of TB vaccine and yet the killer is still among us

In 1921, the first effective tuberculosis (TB) vaccine was used on human subjects to help protect against this lethal disease. Yet, 100 years later in 2021, more than 1.6 million people died from TB across the world, according to the World Health Organization (WHO), making it the top killer infection once again. There is now an urgent need for new vaccine options to help stop this historical killer.
