Yesterday, GeoVax Labs, Corporation. announced the publication of their manuscript titled “A Single-Dose of Modified Vaccinia Ankara Expressing Ebola Virus Like Particles Protects Nonhuman Primates from Lethal Ebola Virus Challenge” in the peer-reviewed open access journal Scientific Reports naturally Research, which shows that just one intramuscular (IM) dose of GeoVax’s Ebola vaccine (GEO-EM01) provided 100% protection in rhesus macaques challenged having a lethal dose of Ebola virus (EBOV).
Created through the National Institute of Allergy and Infectious Illnesses (NIAID), within very-high magnification, this digitally-colorized checking electron micrograph (SEM) depicts just one filamentous Ebola virus particle which had budded in the the surface of a VERO cell from the African eco-friendly monkey kidney epithelial cell line.
GEO-EM01 is dependant on their novel Modified Vaccinia Ankara (MVA) Virus-Like Particle (VLP) platform, which generates noninfectious VLPs within the individual being vaccinated. VLPs mimic an all natural infection, triggering your body to make a robust and sturdy immune response with antibodies and T cells.
This is actually the first are convinced that a replication-deficient MVA vector can confer full protection against a lethal EBOV challenge following a single-dose vaccination in macaques.
Within this study, GEO-EM01 was administered as whether single IM inoculation (prime) or as two IM inoculations in a four-week interval (prime-boost) to categories of four rhesus macaques each. A control group received the MVA vector without Ebola virus protein inserts. Four days after inoculation, creatures in most three groups were uncovered to some lethal dose of Ebola virus. Three from the four unvaccinated creatures died within 12 days, while all the vaccinated creatures survived. Researchers at Rocky Mountain Laboratories, area of the National Institute of Allergy and Infectious Illnesses (NIAID), collaborated within the study.

GEO-EM01 is a element of a tetravalent hemorrhagic fever virus vaccine being produced by GeoVax. Another vaccine components are suitable for protection against Sudan virus (SUDV), Marburg virus (MARV), and Lassa virus (LASV). These vaccines are envisioned as either individual monovalent vaccines in epidemic situations or combined like a tetravalent vaccine for that protection from the countless individuals who reside in at-risk areas, travelers, military personnel, healthcare workers, yet others.
Farshad Guirakhoo, PhD, GeoVax’s Chief Scientific Officer, commented, “GEO-EM01 uses GeoVax’s proven MVA-VLP vaccine platform that’s been proven safe and also to induce durable antibody and T-cell responses in multiple human numerous studies for GeoVax’s prophylactic Aids vaccine. Utilizing the same platform, we’ve proven our Zika vaccine (GEO-ZM02) and our Lassa Fever vaccine (GEO-LM01) to supply single-dose 100% protection in rodents against intracranial challenge. This research is exclusive since the immune response caused following a single dose from the vaccine not just provided full protection against a lethal challenge, but additionally eliminated nature type Ebola challenge virus in the animal’s bloodstream. No live virus might be retrieved anytime point from the vaccinated creatures when compared to controls, which in fact had greater than 100,000 live Ebola infections per ml of bloodstream.”
