Developing Covid-19 vaccines in less than a year came from repurposing multiple, decade-old vaccine research platforms, but too many lives were lost, and a new goal of developing vaccines in 100 days is needed to counter the next global pathogen. This is according to Dr Nicole Lurie, a Strategic Advisor to the UK-based Coalition for Epidemic Preparedness Innovations (CEPI), and an advisor to the World Bank and the World Health Organization, (WHO). She was addressing a virtual global forum on tuberculosis (TB) vaccines on Thursday, 22 April, in a session on how to use lessons from Covid-19 to accelerate responses to the TB burden and antimicrobial resistance worldwide.
