In June 1982, he published his findings in Science, and the spirochete was named Borrelia burgdorferi in his honor.After the identification of B. burgdorferi as the causative agent of Lyme disease, antibiotics were selected for testing, guided by in vitro antibiotic sensitivities, including tetracycline antibiotics, amoxicillin, cefuroxime axetil, intravenous and intramuscular penicillin and intravenous ceftriaxone. The mechanism of tick transmission was also the subject of much discussion. B. burgdorferi spirochetes were identified in tick saliva in 1987, confirming the hypothesis that transmission occurred via tick salivary glands. Society and culture
Urbanization and other anthropogenic factors can be implicated in the spread of Lyme disease to humans. In many areas, expansion of suburban neighborhoods has led to gradual deforestation of surrounding wooded areas and increased border contact between humans and tick-dense areas. Human expansion has also resulted in a reduction of predators that hunt deer as well as mice, chipmunks and other small rodents—the primary reservoirs for Lyme disease. As a consequence of increased human contact with host and vector, the likelihood of transmission of the disease has greatly increased. Researchers are investigating possible links between global warming and the spread of vector-borne diseases, including Lyme disease. Controversy
The term "chronic Lyme disease" is controversial and not recognized in the medical literature, and most medical authorities advise against long-term antibiotic treatment for Lyme disease.
Subsequently, hundreds of vaccine recipients reported they had developed autoimmune and other side effects. Supported by some advocacy groups, a number of class-action lawsuits were filed against GlaxoSmithKline, alleging the vaccine had caused these health problems. These claims were investigated by the FDA and the Centers for Disease Control, which found no connection between the vaccine and the autoimmune complaints.Despite the lack of evidence that the complaints were caused by the vaccine, sales plummeted and LYMErix was withdrawn from the U.S. market by GlaxoSmithKline in February 2002, in the setting of negative media coverage and fears of vaccine side effects. The fate of LYMErix was described in the medical literature as a "cautionary tale"; an editorial in Nature cited the withdrawal of LYMErix as an instance in which "unfounded public fears place pressures on vaccine developers that go beyond reasonable safety considerations." The original developer of the OspA vaccine at the Max Planck Institute told Nature: "This just shows how irrational the world can be ... There was no scientific justification for the first OspA vaccine LYMErix being pulled." VLA15
The hexavalent (OspA) protein subunit-based vaccine candidate VLA15 was developed by Valneva. It was granted fast track designation by the U.S. Food and Drug Administration in July 2017. In April 2020 Pfizer paid $130 million for the rights to the vaccine, and the companies are developing it together, performing multiple phase 2 trials.A phase 3 trial of VLA15 was scheduled for late 2022, recruiting volunteers at test sites located across the northeastern United States and in Europe.
