GlaxoSmithKline's Ebola Vaccine Passes First Human Trial

The first human trials of a vaccine against Ebola have been successful, but it will be months, at best, before it can be used to stem the outbreak in West Africa.

The origins of the vaccine go back more than a decade. A chimpanzee cold virus was modified to carry Ebola genetic material conferring protection against the Zaire strain of Ebola. This was shown to be effective in monkeys, although the benefits wore off with time.

Progress was delayed not by technical obstacles but economics. Previous outbreaks were controlled by tracing and quarantining the sick. With the people most endangered also being the least able to pay, funding was limited. Via Business Insider.

GlaxoSmithKline Takes A Step Closer To Ebola Vaccine

GlaxoSmithKline (GSK) $GSK, the Britain-based pharmaceuticals company is inching closer to finding a vaccine for the deadly virus Ebola. The company's test Ebola vaccine, which has already been tested in nearly 200 people has shown no side effects on healthy human beings so far, which is a positive sign at the early stages of the study.

According to reports on Monday, the safety data so far are very satisfactory, which means there is no threat with regard to the safety of the vaccinated subjects.


Since the trials began about two months ago, the program has used approximately 200 healthy human volunteers from the U.S, Britain, Mali and Switzerland.

The experimental shot uses a single Ebola virus gene from a chimpanzee virus to generate an immune response. Because it doesn’t contain any infectious virus material, it can’t infect those being vaccinated.

Latest statistics from the World Health Organization (WHO) indicate that the latest Ebola outbreak has now infected more than 13,000 people with virtually all of them being from West Africa, especially in Guinea, Sierra Leone, and Liberia. out of these, 5,000 have been reported to have succumbed to the virus.

Reports also suggest that biotech companies are accelerating the drug trials for Ebola vaccine, while WHO remains hopeful that one or more of the vaccines may be ready for some limited use in West Africa, in early 2015.
