An urgent call for increased global investment and political support for TB vaccine R&D. With the United Nations High-Level Meeting on TB taking place on 22 September 2023, this call will play an important part in amplifying the voices of the global TB community in demanding new TB vaccines. This letter is also in direct support of the recently launched call to action ‘Deadly Divide: Priorities to Close the Deadly Divide’ from the Stop TB Partnership community and non-governmental organization delegations.
