BactiVac, the Bacterial Vaccines Network, was established in 2017. The Networks mission is to advance vaccine development against global bacterial infections in humans and animals through a One Health approach, to reduce disease, death, and antimicrobial resistance, and thereby enhance economic development. BactiVac brings together members based in academia, industry, policymakers and funders from high-income countries (HICs) and low- and middle-income countries (LMICs). BactiVac supports bacterial vaccine development through Catalyst Project Awards, and Catalyst Training Awards. This funding targets bottlenecks and capacity-building in bacterial vaccinology, particularly among LMIC early career researchers.
