They had a lyme vaccine at one time---
Developed in the ‘90s by pharmaceutical company SmithKline Beecham (now GlaxoSmithKline), LYMErix was the only licensed Lyme disease vaccine on the market. The vaccine was based on one of the surface proteins expressed by the disease-causing bacterium, which was used to evoke an immune response in the individual. Clinical trials involving more than 10,000 individuals found that LYMErix reduced new infections in adults by close to 80% and conferred protection to 100% of children. Additionally, no serious side-effects were observed.
Despite these positive results, the vaccine was withdrawn from the U.S. market in 2002 due to a combination of factors. Although it was considered a cost-effective approach for Lyme disease, its high cost resulted in slow uptake in clinical settings and reluctance of insurance companies to cough up for it. This, combined with the emergence of a hypothesis that the vaccine sparked immune responses that resulted in arthritis, caused the vaccine’s popularity to plummet.
