It was impossible to know whether the vaccine had shut down a developing infection, or whether she had never been infected in the first place. The idea was that the harmless virus would teach the immune system to recognize harmful potential invaders.But he and students in his lab had been trying for about six years to successfully manipulate VSV to add in the genes of other viruses. But through an unlikely series of twists and turns, some fortuitous and not-so-fortuitous, the vaccine has finally been developed by Merck, approved by regulatory agencies in the It is a feat that built on the work of scientists in multiple countries on three continents who toiled in obscurity for years. I live in the West Indies and I continued to follow the updates on Ebola. (Nine years later, When a scientist named Hans-Dieter Klenk moved to the city in the 1980s to lead the Institute of Virology at the Philipps-University Marburg, there was no research being conducted there on Marburg or Ebola. But as of April 2014, that still hadn’t happened. “That’s just a feeling.’’In June, however, the trial’s data and safety monitoring board concluded there were not likely to be enough additional cases to change the outcome of the study. Later the group made a VSV virus with the G protein of the Marburg virus.Klenk said that, even then, there was some discussion about whether the hybrid VSV virus could be made into Ebola or Marburg vaccines. The lab had even produced human-grade vaccine in the hopes of testing it in people. It’s not uncommon for a live virus vaccine, like rVSV-ZEBOV, to trigger a fever; it’s actually a sign that the immune system has activated. But the group didn’t have high-containment labs in which to do animal studies, so it couldn’t test the theory.Back across the Atlantic, though, Canada was building a new national microbiology laboratory — one that included biosafety level 4 facilities, the type needed to study Ebola. Several methods of DNA vaccine delivery have been used including direct administration into tissue via syringe, gene gun delivery of DNA, or electroporation of muscle tissue following injection of DNA. Abdourahmane Diallo, a public health physician who works for Guinea’s health ministry, was one of those who answered the WHO’s appeal for help. “We worked night and day … trying to get VSV to work and finally got it to work.”On Nov. 11, 2019, Ervebo was approved by the European Commission, the first time it had been licensed by any regulatory agency. What was an appropriate dose? Additionally, they are easily manufactured, cost effective and are stable for storage and shipping at ambient temperatures .

One very good student left his lab, he recalled, because she concluded the work was never going to pan out.Then, in 1994, Rose heard that researchers in Germany had succeeded where he had struggled — with a rabies virus. He recalled that his colleagues were excited at the prospect of taking part in the study. The first vaccine to be approved in the United States was rVSV-ZEBOV in December 2019. “We never heard back,” he said, noting the fact that Phase 1 human trials were already underway may have helped.Still, Kobinger urgently shipped off some doses to Montana so Feldmann could test the vaccine in primates to ensure the change had not affected the vaccine’s efficacy.

Others started working on Phase 1 trials that would be conducted in Switzerland, Germany, Gabon, and Kenya.The WHO and others — including players in the U.S. government — began casting about to find a more experienced pharmaceutical company to partner with, or to acquire the vaccine from NewLink.The list of potential white knights wasn’t long. “It’s just bringing together a number of discrete actions and discrete facts, which each alone would not have made it. And when he left Germany in 1999, he asked Klenk if he could take the VSV construct with him, so he could continue his work.

When IDT had produced vaccine, it shipped back vials to Alimonti who ran the tests to ensure the material was pathogen-free.“Judie did that. Feldmann and others believed the latter was more likely.But, importantly, there were no negative consequences to using the vaccine, a fact that would later give comfort to people who were struggling with whether to deploy rVSV-ZEBOV in a much larger emergency.The monetary asset was a $2 million grant awarded to the Winnipeg lab. As Ebola spread from Guinea to Liberia and Sierra Leone, the group, known by the acronym of its French name, MSF, had been emphatically warning the WHO and others that conditions on the ground were rapidly deteriorating. But somewhere along the line, a key feature in the vaccine had been changed.The human-grade vaccine made by the German contractor contained the glycoprotein from a different Ebola Zaire strain.No one had told Kobinger the change had been made; he discovered that Alimonti, who had done all the work to prepare the materials for IDT Biologika, had used the different glycoprotein on instructions from one of her supervisors.

The grant, though a drop in the bucket when it comes to scientific research, was hard-won. But realistically, it was a nonstarter. So good written and hugely interesting.Really well done story about a very important and encouraging bit of science history. GSK was racing to test its own experimental Ebola vaccine.

He and the team he led had a well-deserved reputation for their work on Ebola and other viral hemorrhagic fevers; Kobinger himself had led development of a promising Ebola therapy.The Winnipeg lab also had been working for years on an Ebola vaccine, one that looked tremendously effective in animal models.
