A New Lyme Disease Vaccine Is Showing Promise

An anonymous reader quotes a report from IFLScience: Promising results have come out of the only active clinical trial for a vaccine against Lyme disease. Valneva, a French biotech company, recently announced its first Phase 2 clinical trial has shown that its vaccine against Lyme disease is both safe and effective. The vaccine works by triggering the body's immune system to produce antibodies for the six common serotypes of the disease that are found in North America and Europe. It does this by introducing an isolated protein of the pathogen to the body, allowing the immune system to recognize and respond to the surface proteins found on the bacteria responsible for Lyme disease, Borrelia burgdorferi. Over 570 healthy adults in the US and Europe were given one of two dose levels of the vaccine in three injections, while others were given a placebo as a control. Both groups that received the active dose were found to have produced a significant amount of antibodies against each of the six most prevalent Outer Surface Protein A serotypes of B. burgdorferi. [...] This new potential vaccine, known as VLA15, is currently the only active Lyme disease vaccine in clinical development. Back in 1998, the US Food and Drug Administration (FDA) approved a Lyme disease vaccine known as LYMErix. It was withdrawn from the market just three years later following doubts over its effectiveness and other contentions. Much of the controversy, however, was often said to have been kicked up by the anti-vaccination movement, which was growing in momentum at the time.
