Scientists unveil new Ebola virus vaccine design
Zhu is the inventor of the vaccine.
When injected, the rVSV-ZEBOV vaccine infects cells and produces copies of the glycoprotein, eliciting an immune response to protect against future exposure to Ebola virus. Tests in Africa amid the aforementioned outbreak suggested it worked well and it was approved by the Food and Drug Administration in late 2019. However, those tests lacked placebo groups and other standard features of typical large-scale phase-III trials. Thus, questions remain on true efficacy.
