[Articles] Fast-acting single-dose vesicular stomatitis virus-Sudan virus vaccine: a challenge study in macaques

We showed that a single dose of VSV-SUDV protected NHPs from lethal SUDV infection within 1 week. The fast-acting nature highlights VSV-SUDV as an ideal countermeasure for ring vaccination during outbreaks of Sudan virus disease pending further preclinical and clinical assessment. In contrast, VSV-EBOV provided no relevant protection against SUDV infection in NHPs, highlighting the need for species-specific filovirus vaccines.
