Ervebo (Ebola Zaire Vaccine, Live/rVSVΔG-ZEBOV-GP): The First Licensed Vaccine for the Prevention of Ebola Virus Disease

Abstract

Objective: To review the clinical data regarding the safety and efficacy of the Ervebo (Ebola Zaire vaccine, live/rVSVΔG-ZEBOV-GP) vaccine for the prevention of the Ebola virus disease. Data Sources: A literature search through PubMed, MEDLINE, and Cochrane Library was conducted for clinical trials published between January 2014 and June 2020 in the English language using the keywords Ervebo, rVSVΔG-ZEBOV, rVSVΔG-ZEBOV-GP, Ebola Zaire, and vaccine. Study Selection and Data Extraction: Articles were selected if they were related to the Food and Drug Administration (FDA) approval of Ervebo (Ebola Zaire vaccine, live/rVSVΔG-ZEBOV-GP) or provided novel data regarding this entity. Twelve articles noted in the FDA approval were chosen, along with 2 additional articles identified as providing novel information. Data Synthesis: The findings of the review show that Ervebo (Ebola Zaire vaccine, live/rVSVΔG-ZEBOV-GP) is a safe, immunogenic, and likely effective vaccine for the prevention of Ebola virus disease. Relevance to Patient Care and Clinical Practice: Ebola virus disease is highly infectious and often fatal. There have been multiple large outbreaks in the past 5 years, with no licensed treatments or vaccines. An effective vaccine could largely curtail current outbreaks and prevent further ones. Conclusion: The recent FDA approval of Ervebo (Ebola Zaire vaccine, live/rVSVΔG-ZEBOV-GP) offers the first approved vaccine for the prevention of Ebola virus disease. It has been shown to be safe, immunogenic, and likely effective for use in real-world applications for those at risk of contracting the disease.
