Timing and Duration of Key Development Milestones towards a Vaccine in First 365 Days of Recent Major Global Outbreaks.

Double lines at 365 days represent ongoing activities. Slanted lines indicate overlap in development milestones; the genomes of Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2; COVID-19) were sequenced and diagnostic tests developed before the World Health Organization (WHO) issued their alert. See Table S1 in the supplemental information online for dates of featured events.
