Leslie Lobel is an American-born Israeli virologist and physician at Ben-Gurion University in Israel, where he is a leading researcher attempting to develop a vaccine and cure for infectious diseases, primarily Ebola.[1] He is Chair of their Department of Virology and Developmental Genetics, and Vice Chair of the Department of Microbiology, Immunology and Genetics.[2]

Partnering with both the U.S. military and the Uganda Virus Research Institute, his focus since moving to Israel in 2002, has been on isolating human monoclonal antibodies as a drug which can be manufactured to give people immunity against a number of infectious diseases. With his co-investigator, Dr. Victoria Yavelsky, he hopes to create a "passive" vaccine which would offer protection immediately after being given.[3]

Early years and education[edit]

Born in Queens, New York, Lobel received his B.A., Summa Cum Laude, in chemistry, from Columbia College of Columbia University, followed by a Ph.D. in virology. He received an M.D. from Columbia University College of Physicians and Surgeons in 1988.[2] He also did post-graduate work at M.I.T. in Boston. He states that he went into virology since the field was small. Later, his interest shifted to oncology and the study of human immune response to cancer.

Research career[edit]

Lobel has been working to isolate monoclonal antibodies for West Nile Fever, Hepatitis C, as well as Ebola, of which he is one of the world's few experts[4] and its only academic researcher outside the U.S.[5] “Ebola is the most lethal virus," he states. "It can kill 90% of those afflicted. And there is no therapy to counter it. There is a vaccine thus far tested in animals, but it takes a relatively long time to build immunity.”[6] As monoclonal antibodies are proteins that attack specific targets, including viruses, bacteria or other foreign bodies, “the antibodies will neutralize the virus, and avoid the dangerous side effects of the existing vaccine,” he says. He anticipates that they will also be useful for treating diseases like smallpox in the event of an outbreak, and would give protection immediately instead of weeks or the month required by typical vaccines.[6]

For this research, he travels to Uganda about four times a year, with the aid of U.S. and other foreign grants, where he studies a variety of infectious viruses. The research relies primarily on obtaining and analyzing blood samples from survivors of Ebola and other diseases. Currently, there are over a 100 Ugandan survivors of Ebola that he contacts during his visits, checking their blood antibody and immunity levels over time, trying to discover how their immune system helped them survive. Such personal surveys would be less possible, he says, had not Israel invested time and effort in partnering with African medical organizations over many decades and gained their trust.[7] He notes that in Africa, neither the medical system nor foreigners are trusted: "They don’t trust white people coming from outside Africa to treat them."[8]

For the 2014 Ebola outbreak in West Africa, Lobel blames the fact that there has been a severe reduction of research into infectious diseases since the 1970s, leading to less surveillance or ability to properly control outbreaks after they start. He sees globalization and global warming as contributing factors, as they have upset the ecological niches of bats, which he feels are the most likely viral reservoirs.[3] The current outbreak, in his opinion, represents a "perfect storm" for a disease such as Ebola, having erupted in poor countries with meager medical care and where governments have little control over their populations.[9]

Lobel adds that besides Ebola, there are other "bad" viruses out there, which the developed world prefers to ignore so long as they aren't affected. This has resulted in little research into other infectious diseases, with the Ebola outbreak becoming a "wake-up call": "Infectious diseases have not gone away," he claims. "They continue to evolve. Viruses never sleep. It’s just that we have slept."[8]
