This vaccine is designed to protect people against North American and European strains of the Lyme disease bacterium. Two large pharmaceutical companies have devoted considerable effort to developing a vaccine for Lyme disease, but there are no vaccines for humans available in the United States today. Double-blind, randomized, placebo-controlled clinical trials—the most rigorous type of clinical trial used today—were completed for each of two Borrelia burgdorferi vaccines manufactured by GlaxoSmithKline (GSK, formerly SmithKline Beecham [SKB]) and Pasteur Merieux Connaught. The novel Lyme borreliosis vaccine VLA15 shows broad protection against Borrelia species expressing six different OspA serotypes. We have previously shown that the Outer surface protein A (OspA) based Lyme borreliosis vaccine VLA15 induces protective immunity in mice. Herein, we report the induction of protective immunity by VLA15 with mouse models using ticks infected with B. burgdorferi (OspA serotype 1), B. afzelii (OspA se …. Lyme disease, or Lyme borreliosis, the most prevalent arthropod-borne disease in the Western world, is caused by spirochetes belonging to the Borrelia burgdorferi sensu lato group and is predominantly transmitted through Ixodes ticks.

The most common sign of infection is an expanding red rash, known as erythema migrans, that appears at the site of the tick bite about a week after it occurred. There is a precedent for the development of bait vaccines to be used as a strategy to reduce the risk of Lyme borreliosis .

A new Lyme disease vaccine – bravery to be rewarded 17-06-2019 This month VacZine Analytics, a UK-based strategic research publisher exclusively focused on vaccines and infectious diseases, releases a brand-new commercial assessment of Lyme Borreliosis (Lyme Disease)vaccines. One of the new approaches is a vaccine, which works by stimulating the immune system to make antibodies that can attack Borrelia burgdorferi and other types of Borrelia, the bacteria that cause Lyme disease, or borreliosis, is caused by the bacterium Borrelia burgdorferi and is transmitted to humans through the bite of an infected blacklegged deer tick. It is the most common tickborne infectious disease in the United States. For now, the only prevention lies in avoiding tick contact but one company, Valneva, is working fervently to develop what they believe will be the world’s first vaccine against Lyme’s disease.

Safety and immunogenicity of a novel multivalent OspA vaccine against Lyme borreliosis in healthy adults: a double-blind, randomised, dose-escalation phase 1 These oral “bait” vaccines are aimed at preventing mice from becoming infected, thereby interrupting the transmission cycle. Some groups are field testing their products with support from the Centers for Disease Control and Prevention (CDC). NIAID-funded investigators have developed an experimental bait—and vaccine—delivery system. Currently there is no human vaccine against Lyme borreliosis, and most research focuses on recombinant protein vaccines, as such a vaccine has been proven to be successful in the past. The expression of recombinant antigens in meningococcal Outer Membrane Vesicles (OMVs), with the OMV functioning bo … 2020-03-23 Lyme disease, or Lyme borreliosis, the most prevalent arthropod-borne disease in the Western world, is caused by spirochetes belonging to the Borrelia burgdorferi sensu lato group and is predominantly transmitted through Ixodes ticks.

In the Booster Phase subjects from the higher dose group who completed their primary immunization schedule according to protocol will be randomized 2:1 to receive an additional higher dose VLA15 vaccination or Placebo at Month 18. VLA15 is a hexavalent, protein subunit-based vaccine candidate targeting the Outer Surface Protein A (OspA) of Borrelia. Pre-clinical data have proven the potential to provide protection against a majority of Borrelia species that are pathogenic for humans. There is currently no Lyme borreliosis vaccine available for humans available for purchase, but a new research has shown how such a vaccine could be made. 2017-09-01 2011-11-01 French vaccines expert Valneva SE announced that the FDA has granted Fast Track designation for its Lyme borreliosis vaccine candidate VLA15. According to the Centers for Disease Control and Prevention (CDC), Lyme disease is the fastest growing vector-borne infectious disease in the United States.
